Yes, if you match the BMS to your motor's amp draw. The 30A version suits loads up to about 768W, and the 50A version suits trolling motors up to about 1,280W. Check max amp draw on the nameplate, not thrust alone. For runtime, divide 768Wh by your load in watts. Expect about 6 to 8 hours at light loads and about 3 to 5 hours at typical trolling speeds, as estimates.
Choose by runtime and motor size. The 30Ah pack gives you 768Wh, and the 60Ah pack gives you 1,536Wh, so it roughly doubles runtime. The 60Ah pack also offers 60A and 100A BMS options for larger motors. Tell us your motor model and typical trip length if you are unsure.
Yes, if your system is already 24V. One 24V pack replaces two 12V batteries wired in series. You get more usable energy, because lead-acid should not go below about 50 percent, while LiFePO4 can use most of its rated capacity. You must switch to a 29.2V LiFePO4 charger and use the Bluetooth app for an accurate percentage, not an old lead-acid gauge.
Use the included 29.2V LiFePO4 charger. The 30Ah pack includes a 29.2V 5A charger and takes about 6 to 7 hours. Do not use a lead-acid or AGM charger. Its desulfation and equalization stages can trigger a BMS lockout. Red means charging or a fault, and green means fully charged or on standby.
Download the JBD or XiaoxiangBMS app on iOS or Android, then open it near the pack. You can see live cell voltages, remaining percent, real-time current, and temperature. You can also turn discharge off remotely when the boat is docked.
It resists splashes, rain, and deck washdown, but it is not meant to be submerged. The end caps are sealed, and the cells are protected by epoxy boards and a PVC wrap. Keep it in a ventilated marine box or an elevated hatch, not in bilge water.
Measure your box first and allow 10 mm extra for cable bends and terminals. The 30Ah pack is 280 x 170 x 75 mm and about 6.0 kg. The 60Ah pack is about 300 x 180 x 160 mm and about 12 kg. Size tolerance is 3 to 5 mm.
The default is an XT60 or XT90 female lead. You can also choose QS8, Anderson, XT90F/M, XT60F/M, or wire only. Leave an order note at checkout and we will solder it before dispatch at no extra charge. For a custom size, tell us your capacity, BMS current, compartment size, and connector type.
You can connect up to two packs in parallel to make 24V 60Ah, but bring both packs to within 0.1V of each other first. Do not connect them in series to make 48V. The internal BMS is not rated for that.
Discharge from minus 20C to 60C, but only charge from 0C to 45C. Do not charge a frozen pack. Warm it above 0C first. For winter storage, keep it at about 50 percent charge in a dry place from 0C to 35C, and top it up before the new season if it is low.
It is rated for 2,000 plus cycles and comes with a 2-year manufacturer warranty. Real cycle life depends on discharge depth, heat, and using the correct charger, so treat the cycle number as a rating under normal use.
Build takes about 7 to 10 working days, then delivery takes about 15 to 20 working days after tracking is provided. US and Canada ship by FedEx or UPS, and the EU ships by DPD or DHL, with duties included. All times are estimates, not guaranteed dates.
Yes, 36V is enough for commuting, light cargo, and most city riding up to 1500W. It keeps the pack smaller, lighter, and cheaper than 48V. If you need higher top speed, heavier torque, or a real 2000W motor, go to 48V, because true 2000W motors are 48V systems, not 36V.
Choose by range, not by voltage. The 30Ah pack gives you 1080Wh, the 40Ah pack gives you 1440Wh, and the 60Ah pack gives you 2160Wh, so range roughly doubles from 30Ah to 60Ah for the same riding style. The 30Ah pack suits daily commuting, the 40Ah pack suits longer commutes and cargo, and the 60Ah pack suits long-haul cargo and all-day riding.
Match the BMS to your motor and controller current, not to the motor wattage alone. For 30Ah, choose 30A up to 1000W, 40A up to 1200W, and 50A up to 1500W. For 40Ah, the options are 30A and 50A. Your BMS continuous rating must be equal to or higher than your controller's current draw.
It depends on your assist level, weight, terrain, and wind, so treat any number as an estimate. You can estimate it yourself: Wh divided by your average power in watts gives you hours, and hours times your average speed gives you distance. A larger Ah pack gives you more hours for the same riding style, not a higher top speed.
Use a 42V charger, not a 36V charger, because a full 36V pack charges to 42.0V. The 30Ah pack includes a 42V 5A charger and takes about 6 to 7 hours. The 40Ah pack also uses a 42V 5A charger and takes about 8 to 9 hours. Do not use a 48V charger on a 36V pack.
Download the JBD or XiaoxiangBMS app on iOS or Android, then open it near the pack. You can see live cell voltages, remaining percent, real-time current, temperature, and cycle count. You can also turn discharge or charge off remotely as an anti-theft measure.
It resists road spray, puddle splashing, and light rain, but it is not meant to be submerged. The PVC pack uses epoxy boards and PVC heat shrink with liquid sealant at both wire exits. For heavy rain or muddy riding, keep it inside a water-resistant frame bag or enclosure. Metal case packs add a hard shell and a fireproof bag, but the plugs and charge ports stay the vulnerable points.
Measure your triangle or compartment first and allow 3 to 5 mm extra clearance for insulation and cables. The 30Ah PVC pack measures 230 x 135 x 75 mm and weighs about 4.5 kg. The 30Ah metal case pack measures 300 x 190 x 90 mm. If your space is different, tell us the dimensions before ordering and we will tell you which size fits.
Choose your connector at checkout, including QS8, Anderson, XT60, XT90, or wire only, or leave an order note with your connector type and wire length. Every pack is built to order and bench tested before it ships. Tell us your voltage, capacity, BMS current, and compartment size if you need a custom size.
You can ride down to minus 20C, but sub-freezing temperatures can cut range by 15 to 25 percent as an estimate. Never charge below 0C. Bring the pack inside and let it reach room temperature before plugging in the 42V charger. For storage, keep it at about 50 percent charge in a cool, dry place, and do not leave it empty or fully charged for months.
It comes with a 2-year manufacturer warranty. The Samsung 50G packs are rated for 2 years or 600 cycles at 70 percent capacity or above, whichever comes first. To make a claim, email support@booant.com with your order number and a complete BMS diagnostic report. Do not return the old battery on your own.
Every pack is built fresh to order, not pulled from old stock. Build takes about 7 to 10 working days, then delivery takes about 15 to 20 working days after tracking is provided. US and Canada ship by FedEx or UPS, and the EU ships by DPD, with duties included. All times are estimates, not guaranteed dates.
A 48V system is the absolute baseline for anyone looking for real electric performance. Unlike weaker 36V setups that bog down the second you hit a mild incline, a proper 48V setup delivers punchy torque, solid acceleration, and enough speed to safely keep up with urban traffic. It gives you the perfect balance of raw power, excellent energy efficiency, and a highly manageable battery footprint that fits beautifully on most standard bicycle frames.
It’s all about where the battery is going to live and what kind of riding you do:
BOOANT 48V 20Ah Triangle Battery: Specifically engineered to bolt right into the center triangle of your bike frame. It comes with a custom-matched tough frame bag, keeping your bike's center of gravity low and perfectly balanced for aggressive handling.
48V 30Ah Lightweight Battery Pack: Look, here’s the honest deal on this one—our 48V 30Ah configuration does NOT use a heavy metal case. It is wrapped in a premium, high-temperature PVC film. We designed it this way intentionally to keep the pack incredibly lightweight, compact, and flexible enough to easily stuff inside a standard rack bag or rear pannier without throwing off your bike's balance.
48V 50Ah Metal Case Battery: This one is built like a bulletproof tank. Because a massive 50Ah capacity carries serious weight and is typically used for long-haul cargo bikes, delivery rigs, or high-power mopeds, it features a rugged metal case enclosure to act as armor against brutal road vibrations, debris, and physical drops.
Think of Amp-hours (Ah) as your fuel tank capacity. The voltage (48V) dictates your top speed, but the Ah determines how far you can ride before pushing the bike home:
48V 20Ah: Ideal for standard daily commutes, quick trail loops, or riders who want to keep the total bike weight as nimble as possible.
48V 30Ah: The ultimate crowd-pleaser and our best-seller. Perfect for heavy commuters, food delivery riders, or weekend explorers who want zero range anxiety during long sessions.
48V 50Ah: A pure long-range endurance weapon. Built for heavy-duty cargo hauling or riders who want to go 80+ miles on a single charge without pedaling.
Because cheap, generic, no-name cells are a total nightmare. They drop half their capacity within six months, and they experience massive "voltage sag"—meaning your bike will suddenly feel sluggish the second you hit a hill or twist the throttle.
At BOOANT, we build these premium packs using authentic, grade-A Samsung INR21700-50G cells. These brand-name 21700 cells are legendary for holding their capacity over hundreds of charge cycles, running incredibly cool under heavy electrical loads, and ensuring you get stable, predictable power from the moment you turn the key until the pack is empty.
Yes, you can track everything live right on your phone! Every single BOOANT 48V battery pack comes integrated with a heavy-duty JBD Smart Bluetooth BMS (Battery Management System).
The BMS acts as the brain and safety guard for the cells—it balances the cell rows during charging, prevents overcharging, stops the battery from draining too low, and kills the circuit instantly if it detects a short. Since it’s a "Smart" Bluetooth version, you can download a dedicated app to check your exact cell string voltages, live operating temperature, and true remaining capacity percentage in real time.
We don't choke your system's power with thin, sketchy wiring. While a lot of budget brands skimp out and use 12AWG wires, we configure our setups with thick, premium 10AWG heavy-duty silicone copper cables. This ensures your motor controller can draw all the raw current it needs safely without the wires heating up or melting.
For charging, a 48V lithium battery requires a maximum charging voltage of 54.6V. Instead of packing in a painfully slow 2A or 4A brick that leaves you waiting half the day, our full kits come standard with a fast 54.6V 5A smart charger. It safely cuts your charging downtime in half while monitoring thermal thresholds. When the charger light turns green, leave it plugged in for an extra 30–60 minutes—this gives the JBD BMS the time it needs to perfectly "top-balance" the Samsung cells for maximum future range.
They are tightly sealed against heavy road splashes and rain, but no high-power lithium battery is a submarine.
Riding through a rainy commute is completely fine. However, if you are running the PVC-wrapped versions, we always recommend keeping them inside a water-resistant bag or enclosure. If you are using the metal case version, the shell sheds water beautifully, but the main discharge plugs and charging ports are always the vulnerable spots. Never submerge the battery pack or blast it directly with a high-pressure car washer unless you want to trip the BMS safety locks.
Upgrading to a 52V battery is the single best mod you can do for a 48V e-bike system. It gives you a noticeable boost in top-speed and significantly crisper throttle response.
But the real magic is how it handles "voltage sag." When a 48V battery gets down to half capacity, your bike starts feeling sluggish, especially on hills. Because a 52V pack starts at a higher total voltage, it sustains that "fully charged" punchy feeling for way longer during your ride. Best of all, most high-quality 48V motor controllers can handle the 58.8V max charge of a 52V pack without any issues, making it a seamless plug-and-play performance upgrade.
It all comes down to where the battery is going to live on your frame and how much abuse it's going to take:
52V Triangle Batteries (20Ah & 30Ah): Specifically shaped to fit right inside the main triangle of your bike frame. They come with a custom frame bag, keeping the weight perfectly centered and low for optimal handling. It’s the ultimate setup for custom DIY e-bike conversions.
52V Metal Case Batteries (30Ah & 50Ah): Built like an absolute tank. These feature a rugged metal case housing designed for heavy-duty cargo bikes, long-range commuters, or high-speed setups where the pack is exposed to the elements or potential drops. If you need pure structural armor, go with the metal case.
Standard Rectangular PVC Pack (30Ah): Super slim, lightweight, and versatile. Perfect if you are hiding the battery inside a custom rear rack, a pannier bag, or a specialized frame compartment where space is tight.
Think of Amp-hours (Ah) as your fuel tank capacity. Since all these packs run at 52V, more Ah translates directly to more miles on the trail or road:
52V 20Ah Triangle: Ideal for quick daily commutes or trail rides where keeping the bike agile and lightweight is your priority.
52V 30Ah (Triangle, PVC, or Metal): The absolute sweet spot for the vast majority of riders. It easily obliterates range anxiety for long weekend cruises or delivery shifts without adding massive bulk.
52V 50Ah Metal Case: A pure long-range weapon. Packed with massive energy reserves, this is built for heavy-duty cargo haulers, high-current hub motors, or riders who want to travel 80+ miles on a single charge without ever touching the pedals.
Because we refuse to use cheap, generic, no-name cells that lose half their life in six months and get dangerously hot under load. We build these premium packs using authentic, grade-A Samsung INR21700-50G cells.
Samsung 21700 cells are legendary in the e-bike community for two reasons: incredible energy density (more power in a smaller space) and phenomenal longevity. They run incredibly cool even when you are pinning the throttle up a steep hill, and they hold their capacity for hundreds of charge cycles, saving you from buying a replacement battery anytime soon.
Yes, you can track everything live. Every single one of our 52V packs features a built-in heavy-duty JBD Smart Bluetooth BMS (Battery Management System).
The BMS acts as the bodyguard for those premium Samsung cells—it prevents overcharging, stops the battery from draining too low, and shuts things down instantly if it detects a short circuit. Because it's a "Smart" Bluetooth version, you don't have to guess what's going on. Just open the dedicated app on your phone while you're taking a break, and you can see your exact cell voltages, live temperature, and precise battery percentage in real time.
We don't choke your power with thin, budget wiring. We wire our 52V packs with premium 10AWG heavy-duty copper cables. A lot of companies use 12AWG, but 10AWG ensures your controller can pull all the current it needs safely without the wires getting warm.
For charging, a 52V battery requires a dedicated 58.8V smart charger. Never use a 54.6V charger (meant for 48V packs), or it will leave your battery mostly flat. Our chargers use a smart multi-stage process that cuts power automatically once the cells hit 58.8V. When the charger light turns green, leave it plugged in for an extra 30–60 minutes—this gives the JBD BMS enough time to perfectly "top-balance" the cell rows for maximum range.
They are tightly sealed against heavy road splashes and rain, but no high-power e-bike battery is a submarine.
If you're rocking the PVC-wrapped triangle batteries, the included frame bag adds a great layer of protection, but in a massive downpour, you want to make sure the bag stays dry. If you have the metal case versions, they shed water beautifully, but the main discharge plugs and charge ports are always the vulnerable spots. Riding through rain is completely fine, but never submerge the battery or blast it directly with a high-pressure washer unless you want to trip the BMS safety features.
A 60V system is the ultimate sweet spot for riders who want high speed and massive hill-climbing torque without the extreme weight, size, and massive price tag of a 72V monster setup.
It is the go-to upgrade for standard 48V e-bikes or scooters looking for a significant top-speed boost, and it's the factory standard for many high-power electric mopeds and motorcycles. Going 60V allows your motor to run way more efficiently, generating less heat while giving you that snappy throttle response you actually want when pulling away from traffic.
Think of Amp-hours (Ah) as the size of your fuel tank. The voltage gives you the speed, but the Ah gives you the miles. Here is the quick breakdown to help you choose:
60V 20Ah (Compact Power): Perfect for shorter, fast daily commutes or lighter rides where saving space and reducing battery weight is your main goal.
60V 30Ah (The All-Rounder): The absolute sweet spot for most riders. It offers a massive range extension for food delivery riders, heavy commuters, or weekend trail explorers without feeling like a brick on your bike.
60V 40Ah (High-Performance Monster): Designed for heavy-duty setups, massive cargo loads, or high-power motor controllers that pull massive amps constantly. If you hate range anxiety, this is your weapon.
It all comes down to where you are mounting the pack and how rough your riding style is:
60V 30Ah Lightweight PVC Wrap Pack: We wrapped this pack in a high-temperature, tightly sealed PVC film to keep it as slim and light as humanly possible. This is ideal if you are sliding the battery into a central frame bag, an under-seat compartment, or a custom enclosure where every ounce of weight savings matters.
60V 30Ah Metal Case Motorcycle Battery: This is built like armor. We engineered a rugged metal housing to shield the cells from violent vibrations, road debris, and heavy physical impacts. If you are riding a Sur-Ron style e-moto, a heavy moped, or tearing up rough off-road trails at 35+ mph, you want the structural safety of the metal case enclosure.
Because we don't cheat you with cheap, generic cells that sag the moment you hit a hill. We only use authentic, grade-A brand-name cells, but we choose them based on the battery's job:
Samsung INR21700-50G: Excellent energy density and phenomenal longevity. These are used in our 20Ah and 30Ah setups to give you the maximum amount of capacity and range in the smallest possible physical footprint.
Samsung INR21700-50S: These are ultra-high discharge, premium cells used specifically in our 60V 40Ah High-Performance pack. The 50S cell can output massive continuous currents without sweating or overheating. If you are running a high-amp aftermarket controller and want zero "voltage sag" when pinning the throttle open, the 50S-powered 40Ah pack is an absolute beast.
Yes, as long as your motor controller is rated for a 60V system. Our batteries are fully compatible with standard factory setups as well as popular high-power aftermarket controllers (like Sabvoton, Kelly, or Votol).
Every single one of our 60V packs comes integrated with a heavy-duty Smart Bluetooth BMS. The BMS keeps the cells perfectly balanced and protected. Plus, it lets you monitor your live amp draw, cell voltages, and temperatures right through an app on your phone. If you have a specific high-current controller setup, just let us know your max controller amps before ordering, and we can make sure the BMS is configured to handle your exact peak power demands.
A 60V lithium battery pack has a nominal voltage of 60V, but it requires an 67.2V smart charger to reach a full 100% charge. Never try to use a 54.6V or 84V charger on a 60V pack—the BMS will instantly trip its safety lock-down to prevent severe damage.
We configure our high-capacity kits with premium, fast smart chargers that utilize a multi-stage CC/CV charging process to safely cut your downtime in half. When the charger light turns green, the bulk charging is done, but we always recommend leaving it plugged in for an extra 30–60 minutes. This gives the Smart BMS enough time to perfectly "top-balance" the individual cell strings, ensuring you get maximum range and a much longer overall battery lifespan.
We absolutely hate thin, bottlenecked wires that get warm under load. That’s why we configure our high-power 60V setups with thick, premium 10AWG heavy-duty silicone copper cables to handle high-current demands smoothly and safely.
For the main power discharge ports, we equip them with high-current, gold-plated connectors like XT90-Anti Spark or Anderson connectors depending on your bike's requirements. The anti-spark technology is critical for 60V systems because it completely eliminates that scary, loud "pop" sound when you first plug the high-voltage battery into your motor controller.
If you want serious speed, massive torque, and the ability to fly up steep hills without your motor bogging down, 72V is the holy grail.
Moving up to a 72V system gives you insane high-power performance. Because higher voltage means your system can pull more total wattage while actually drawing fewer amps to do the same amount of work, it keeps your motor running more efficiently and significantly cuts down on system heat. It turns a standard commuter e-bike into a high-speed electric beast.
We use top-tier, authentic grade-A Samsung INR21700-50G and ultra-high discharge Samsung INR21700-50S cells.
This matters immensely for a 72V build. Cheap, generic cells will experience massive "voltage sag" the second you twist the throttle, causing your bike to cut out or lose power under heavy loads. Samsung 21700 cells are built to sustain heavy continuous discharge currents without breaking a sweat, ensuring you get full, raw power from 100% all the way down to empty, while drastically extending the lifespan of the entire pack.
Our standard daily-driver build features a heavy-duty JBD Smart Bluetooth BMS which is perfect for most high-performance setups and lets you track your cell health right on your phone app.
However, if you are building an absolute monster with a high-current controller (like a Sabvoton or Kelly controller), we can fully customize your pack with a JK Smart BMS or an ANT BMS. The JK BMS is particularly popular for massive 72V rigs because it features active balancing, which actively moves energy between cells to keep the high-voltage pack perfectly in sync under brutal riding conditions. Just tell us your controller specs, and we’ll install the right brain for the job.
Let’s cut through the marketing fluff: range entirely depends on how heavy your right hand is.
A 30Ah capacity at 72V gives you a massive energy reserve (over 2100 watt-hours). If you are cruising moderately at around 20-25 mph with some pedaling, you can easily pull 60 to 80+ miles out of a single charge. But let's be honest—you're buying a 72V battery to go fast. If you're pinning the throttle open and ripping at 45+ mph on pure throttle, wind resistance will eat up power fast, dropping your real-world range closer to 35-45 miles.
We don't let thin wires choke your power or heat up your bike. Standard 12AWG wires just can't cut it here. We build our 72V packs with premium, thick 10AWG heavy-duty silicone copper cables that can easily handle high continuous current draws without getting warm.
For the main power connectors, we usually equip them with high-current QS8, QS10, or XT90-Anti Spark connectors depending on your specific controller requirements. The anti-spark feature is vital for 72V systems to prevent that loud, scary "pop" when you first plug the battery into your controller.
A 72V lithium pack requires a dedicated 84V smart charger (never use a 54.6V or 58.8V charger, as they won't charge it at all).
Our smart chargers feature a multi-stage charging process that cuts off completely once the cells hit 84V. Because it's moving serious power, the charger's internal cooling fan will run fast and make a whirring noise—that's normal and safe. While both the smart charger and the BMS have automatic overcharge protection, we always recommend unplugging the battery once it's full. Never leave a high-voltage battery charging unattended for days or while you are away from home.
We actually build and offer both versions, because it totally depends on your specific bike setup and how you ride. Here is how to choose the right one for your project:
The Lightweight PVC Wrap Version: This is the go-to choice if you are building a custom stealth e-bike and plan to put the battery inside a central triangle frame bag. The high-temperature PVC wrap keeps the battery pack incredibly lightweight, slim, and flexible enough to fit perfectly into tight spaces without adding unnecessary bulk.
The Rugged Metal Case Enclosure: This is engineered for heavy-duty setups, high-speed electric motorcycles (E-motos), or custom bomber-style frames. When you are tearing up rough trails or ripping at 45+ mph, your bike takes a beating from heavy vibrations and road debris. The solid metal case acts like armor—it offers maximum impact resistance, seals out the elements, and gives you ultimate structural safety where the power is serious.
If you need a nimble, bag-mounted setup, go with PVC. If you need pure, bulletproof protection on a high-power rig, grab the metal case.
A standard budget charger is dumb—it just forces current into the battery continuously until it runs hot or you manually pull the plug. A Smart Charger acts like a technician for your pack.
Our high-quality chargers use a multi-stage charging process (CC/CV—Constant Current then Constant Voltage). It pumps in full power safely while the battery is empty, but as it gets close to full, the charger automatically throttles back the speed. Once the cells hit their exact maximum voltage, it shuts off completely to prevent overcharging. Plus, it has built-in short circuit and reverse polarity protection, so you don’t spark anything if you plug it in wrong.
Because life is too short to spend 12 hours waiting for a battery to charge. A standard 2A charger is fine for a tiny scooter, but if you have a massive high-capacity pack (like our 48V or 52V 30Ah triangle lithium batteries), a 2A brick will take ages.
We bundle our kits with a premium 54.6V 5A smart charger for 48V setups (and matching higher voltage smart chargers for 52V or 72V builds). A 5A charger safely cuts your downtime in half, letting you get back out on the trail or road much faster without generating dangerous amounts of heat.
This is super important: Never match the nominal voltage of the battery directly to the number on the charger sticker. You need to look at the maximum charge voltage.
For a 48V lithium battery pack, you need a 54.6V smart charger.
For a 52V lithium battery pack, you need a 58.8V smart charger.
For a 72V lithium battery pack, you need an 84V smart charger.
Using a 48V charger on a 52V battery will leave it completely flat, and using a 72V charger on a 48V battery will instantly fry your JBD Smart BMS or ruin the cells. Always double-check the voltage output label before plugging it in.
Yes, it is 100% normal. Moving 5 Amps of current generates a lot of kinetic heat. Our smart chargers are engineered with a heavy-duty aluminum alloy casing that acts as a heat sink, along with a high-speed internal cooling fan to push that heat out.
Because the fan runs fast to keep things safe, it will make some whirring noise. Just make sure you place the charger on a hard, flat surface (like a concrete floor or a desk) in a well-ventilated area while it's working. Never leave it on a bed, carpet, or wrapped in a cloth, or it will overheat and trip its own thermal shutdown switch.
Don't worry, your setup is working perfectly. The smart charger turns green when the overall current drops below a certain threshold (usually around 0.2A to 0.5A), signaling that the bulk charging phase is done.
However, your JBD Smart Bluetooth BMS is still hard at work in the background doing "top-balance." It slowly bleeds off energy from the highest cell rows to let the lower rows catch up to a perfect 100% line. When the light turns green, we always recommend leaving the charger plugged in for an extra 30 to 60 minutes. This gives the BMS enough time to perfectly balance the pack, which extends your overall battery lifespan.
Mechanically, the smart charger and your BMS will shut off the power automatically when the pack is full, so it won't explode if you leave it overnight.
However, as a safety best practice for any high-power lithium device, we strongly advise against leaving it plugged in indefinitely or charging while you sleep. Once the light has been green for an hour and your app shows a healthy balance, unplug it from both the wall and the battery. It's just a smarter, safer routine to get into.
Absolutely. We ship our custom battery and charger kits globally, so we match the AC input plug to your shipping destination automatically.
Whether you need a standard US/Canada 3-prong plug (110V), a European Schuko plug (220V), or a UK plug, we will configure the correct wall adapter and ensure the charger internal transformer handles your local grid voltage perfectly. You won’t need any sketchy travel adapters—just plug it straight into your wall outlet.
Don't overthink it—always look at your motor controller first. If your controller says 48V, a 48V battery is your safe, go-to choice.
But if you want a little more punch? Many riders running a 48V setup upgrade to a 52V battery. It gives you a nice boost in top-speed and stops that annoying "voltage sag" when you're grinding up steep hills. Just make sure your controller can take a 58.8V max charge. Now, if you're building a high-power beast or a heavy cargo rig running a 72V system, you have to match it with a 72V battery. Mixing those up will either fry your electronics or leave you stranded.
Because cheap, generic cells are a nightmare waiting to happen. They lose capacity in six months and sag the moment you hit the throttle. We build our premium packs using legitimate, grade-A Samsung INR21700-50G and Samsung INR21700-50S cells (and heavy-duty 32700 LiFePO4 cells for specific long-life builds).
Think of brand-name Samsung 21700 cells as an insurance policy. They hold their capacity for years, run way cooler under heavy loads, and won't leave you pushing your bike home.
Yes, and you absolutely want the "Smart" version. The BMS (Battery Management System) is basically the bouncer for your battery. It keeps the cells balanced, prevents overcharging, and shuts things down if it detects a short circuit.
But since ours is a JBD Smart Bluetooth BMS, you don't have to guess what's happening inside the pack. You just open an app on your phone while you're riding, and you can see your exact cell voltage, live temperature, and precise battery percentage. No more guessing.
Because we hate waiting, and we hate melted wires. A lot of budget batteries use thin 12AWG wires that get sketchy and warm when you push them hard. We went with thick 10AWG heavy-duty copper cables so your motor can pull all the current it needs safely.
Also, nobody wants to wait 12 hours for a battery to charge. Instead of a slow 2A or 4A brick, our kits come with a fast 54.6V 5A smart charger. It cuts your downtime in half without cooking your cells.
We handle the whole cross-border headache for you. Since lithium batteries are classified as dangerous goods, we don't just dump them in the regular mail.
We ship them from China via specialized air or ocean freight forwarders who handle the customs clearance. Once it clears customs in the US, Canada, or Europe, a local carrier like FedEx, UPS, or DPD takes over and drops it right at your door. You won't have to deal with paperwork or hidden fees.
Let’s be real—no e-bike battery is a submarine. Our PVC-wrapped triangle batteries are tightly sealed against splashes and light rain, but you still need to protect them. If you’re riding through a heavy downpour, you absolutely want a good, water-resistant frame bag to shield the pack.
For our metal case batteries, the shell handles water much better, but the plugs and discharge ports are always the vulnerable spots. Ride through the rain? Sure. Pressure wash your battery or submerge it? Absolutely not, unless you want to fry the JBD BMS.
There’s no magic number because it depends on how hard you twist that throttle. But with a massive 30Ah capacity, you have a ton of juice.
If you’re riding a regular 52V setup and doing moderate pedaling, you can easily look at 50 to 70+ miles. If you're ripping a heavy 72V high-power build at 40 mph without pedaling at all, expect that range to drop significantly—closer to 30–40 miles because wind resistance at high speeds just eats up energy. More speed always equals less miles, but 30Ah gives you the biggest safety net you can get.
Yes, but you have to do it right. You can run them in parallel to double your amp-hours (Ah), but never mix voltages (don't connect a 48V to a 52V). Also, before you plug them together, both batteries must be charged to the exact same voltage level. If one is full and the other is empty, the full one will dump massive current into the empty one instantly, which can damage the wires or trip the Smart BMS.
To be 100% safe, we always recommend using a dual battery balancer switch module instead of a cheap Y-splitter cable.
Don't panic, your battery isn't broken—it’s just basic chemistry. Lithium ions inside those Samsung 21700 cells get sluggish when the temperature drops below freezing. You might notice about a 15% to 20% drop in range during dead winter.
Here is the golden rule for winter: Never charge your battery if the pack itself is frozen (below 32°F / 0°C). Bring the battery inside, let it warm up to room temperature for a couple of hours, and then plug in the 5A charger. Charging a frozen lithium pack can permanently ruin the cells.
Whatever you do, do not leave it plugged into the charger, and do not store it completely dead. Both will kill its lifespan.
The sweet spot for lithium storage is around 50% to 60% capacity (roughly 3.7V to 3.8V per cell). Leave it in a cool, dry place inside your house—not in a freezing garage or a boiling hot attic. Since our packs have a Bluetooth BMS, you can easily check the app once a month just to make sure the charge hasn't dropped too low. If it falls below 40%, give it a quick top-off with the charger for an hour and put it back to sleep.
Think of the BMS (Battery Management System) as the brain and the bodyguard of your lithium pack. Without it, your high-capacity battery is basically a ticking time bomb. A good BMS constantly watches over every single cell row, making sure they don’t overcharge, drain too low, get too hot, or short circuit.
We don't use generic, nameless BMS boards. We want you to ride with peace of mind, which is why we equip our premium packs with smart, heavy-duty management systems that keep your battery running safely for years, not months.
A standard old-school BMS runs blindly in the background—you never know what it's doing until something breaks. A Smart BMS has a built-in Bluetooth module.
Our go-to standard is the JBD Smart Bluetooth BMS because it is incredibly reliable and widely trusted in the e-bike and DIY community. When you're out riding, you can just open a dedicated app on your phone. It shows you the exact voltage of every individual cell string, the live temperature of the pack, how many amps your motor is pulling, and the exact remaining capacity. No more guessing games.
Absolutely! While JBD is our reliable daily driver, we know that many hard-core builders running massive 72V systems or heavy-duty cargo cargo setups have specific preferences.
If you want a JK Smart BMS for its massive active balancing current, or an ANT BMS because it fits your specific high-current display setup, just let us know before you place your order. We can fully customize the build and wire up the exact BMS your project demands.
This is huge if you want your pack to last. Most standard JBD boards use passive balancing, which bleeds off excess energy from the highest-charged cells as heat to let the lower cells catch up. It’s slow, but it works perfectly for standard 48V or 52V commuter packs.
However, if you choose to upgrade to a JK BMS, it features true active balancing. Instead of wasting energy as heat, it actually takes high currents from the strongest cells and pumps it directly into the weaker ones. This keeps high-voltage, high-capacity packs perfectly in sync, giving you maximum capacity and a longer overall battery lifespan.
You can, but you need to be careful. The JBD or JK app lets you tweak things like low-voltage cutoffs or over-current protection limits.
We pre-configure every single battery pack with safe, optimized parameters tailored specifically to the Samsung 21700 or LiFePO4 cells inside before it ships out. If you're a seasoned technician who knows exactly what you're doing, feel free to monitor and adjust. But if you're not sure, leave the settings alone—setting the cutoff thresholds incorrectly can easily trip the BMS or damage the cells.
It immediately goes into lock-down mode to save your battery (and your bike). If the BMS detects a sudden massive short circuit, over-current draw, or if the cells get too hot while you're grinding up a massive hill, it will instantly shut off the discharge port.
If your battery suddenly cuts out, don't panic. Check the Bluetooth app—it will show you an error code (like "Over-Temperature Protection" or "Short Circuit"). Once the pack cools down or the short is resolved, the BMS will automatically reset, or you can manually reset it through the app to get back on the road.
We accept PayPal and major credit and debit cards, including Visa, Mastercard, American Express, and JCB. Payment is taken securely at checkout.
Yes, in some cases, but please contact us first and do not ship anything back on your own. Lithium batteries need special handling for transport. Contact us within 14 days of delivery, and the product must be unused, uninstalled, and unmodified, in its original packaging when possible.
