Heavy-Duty JBD BMS | The Invisible Bodyguard
Cheap generic batteries use bottom-dollar circuit boards that pull the plug only *after* your cells are already fried. We don't cut corners. BOOANT batteries run on an authentic, heavy-duty JBD smart board that actively micro-manages the internal hardware so you can ride hard without stressing.
Handles Constant High-Amp Abuse
Built with heavy-duty MOSFETs and thick 10AWG low-resistance silicone wiring. Whether you choose the 40A, 60A, or 80A version, this board dumps raw, continuous power directly to your controller without overheating, melting down, or tripping the breaker on brutal uphill climbs.
Keeps All 14S Cell Aligned
With a massive 140-cell matrix, some cell groups naturally start to drift apart over time. Our board fixes this automatically. During the final phase of every charge cycle, it actively bleeds off high cells and pulls the lagging ones up, preventing premature voltage sag when you rip the throttle.
Stops Over-Discharge Dead
Leaving a battery sitting dead will destroy the cells. The JBD board is hard-coded to step in and shut down the discharge gate the exact millisecond the pack hits its safe minimum floor of 39.2V (2.8V per Cell). It locks out power completely to guarantee you get the long cycle life you paid for.
Hot & Cold Weather Ready
Equipped with dual thermal probes inside the core. If aggressive summer riding pushes internal heat to 65°C (149°F), the board kills the current before things get sketchy. In the winter, it automatically blocks incoming charger current if temps drop below freezing (0°C/32°F) to stop permanent cell damage dead.
Smart Balancing & Live App Control
Managing a massive 140-cell matrix requires absolute transparency. The integrated JBD Smart BMS balances your cells at the hardware level and beams raw, honest diagnostic data straight to your phone.
Armor Breakdown | Explore the Metal Shell
Plastic battery housings fracture easily and thin PVC wraps offer zero puncture protection when your ride takes a hard spill. Our heavy-gauge steel shell provides absolute physical armor, absorbing heavy mechanical impacts without deforming or risking internal cell damage.
Aggressive off-road trails and bumpy city streets subject heavy 13 kg batteries to constant high-frequency vibration. This rigid industrial enclosure prevents the internal 140-cell grid from shifting, ensuring your nickel strips and spot welds never snap under stress.
Pushing a continuous 80A current generates intense internal heat. The solid metallic surface of this enclosure acts as a natural heat exchanger, drawing thermal build-up away from the core cell strings and dissipating it into the air to prolong cell life.
This is not a generic commuter e-bike battery. This tough-built, weather-resistant structural casing is specifically engineered to handle the brutal daily demands of heavy cargo delivery fleets, multi-wheel electric trikes, and extreme DIY custom e-mobility projects.
Integrated Smart LCD Status Display
Get a complete snapshot of your battery metrics at a single glance. Built right into the top of the heavy-duty metal enclosure, this integrated smart LCD display screen gives you real-time on-chassis diagnostics. It lets you monitor critical system parameters on the fly, offering ultimate convenience whether you are charging in the garage or pausing mid-route.
Get an accurate digital percentage readout of your remaining capacity down to the exact digit. No more guessing with vague 4-bar LED indicators.
Monitor your active pack voltage and internal temperature probes in real time to ensure your cell matrix is running in its safe zone.
Easily keep track of your 10A fast charging progress from 0% to 100% without needing to power on your bike or custom EV setup.
Skip the hassle of pulling out your smartphone, opening an app, and waiting for the Bluetooth connection to sync while riding. Just glance down at the armored display screen for immediate operational reassurance before you hit the trail or kick off a heavy cargo run.

Before You Order | Pre-Purchase FAQ
Which JBD BMS option matches my setup?
You should choose based on the max continuous amp draw of your controller, not just the motor wattage:
- 40A BMS Version: Best for standard hub or mid-drive setups up to 1500W.
- 60A BMS Version: Designed for high-torque systems up to 2500W (Perfect for heavy cargo trikes and commercial builds).
- 80A BMS Version: Engineered for extreme DIY EV projects running up to 3000W setups that demand raw, continuous power.
If you aren't sure about your controller’s specs, drop us a message at our support desk with your motor model before ordering.
Can I get a custom discharge connector for my controller?
Yes, 100%. We make it completely plug-and-play so you don't have to do any dangerous soldering yourself. Our factory will pre-terminate our thick 10AWG silicone cables with whatever connector your setup uses—whether it's an XT90-S Anti-Spark, genuine Anderson plugs, XT60, or heavy copper ring terminals. Just select your option or leave a note on the cart page.
How does the smartphone app monitoring work?
The pack has a built-in JBD Bluetooth module. Just download the official Xiaoxiang App (available for free on iOS and Android). Once connected, you can view the live voltage of each individual cell string, see exactly how many amps you are drawing while riding, monitor internal temperature probes, and track your true remaining percentage.
Is the fast charger included? How long does it take?
Yes, a premium BOOANT 58.8V 10A Smart Fast Charger is bundled in the box. Because it pumps out a true 10A current, it can fully charge this massive 2600Wh vault from empty to full in about 5 to 6 hours (standard 2A chargers would take over 24 hours).
*Note for standby: The charger's LED indicator will show a green light when it is plugged into the wall but disconnected from the battery. This is normal standby status, not a fault. It turns red when actively charging.
How should I store this battery during the winter?
Lithium cells hate being stored completely dead or 100% full. For seasonal storage, charge or discharge the pack to around 50-60% capacity. Use the digital ON/OFF switch inside the app to completely isolate the discharge circuit—this prevents background parasitic drain so you don't have to pull out heavy power cables. Store it in a cool, dry place and check the voltage every 2-3 months.
How do you handle the 2-year warranty if something goes wrong?
We own our production facility and assemble these packs directly, so we don't pass you off to middle-men. Your pack is covered by a 2-Year Comprehensive Factory Warranty covering cell defects, balancing failures, or BMS errors. If an issue pops up, our engineering support team will troubleshoot with you directly to get you back on the road.
