BMS Discharge Current & Motor Matching

Don't guess your setup. Match your e-bike controller's amp draw and motor wattage with our pre-configured JBD Smart BMS setups. Selecting the right map ensures peak efficiency and prevents safety cut-offs under heavy loads.

Standard Setup
30A Continuous
For 250W - 900W Motors
Perfect for legal street e-bikes & commuters
Maximum runtime and lowest thermal buildup
Est. Range: 55 - 75+ miles (PAS mode)
Best Choice
High Range Sweet Spot
40A Continuous
For 800W - 1200W Motors
Tailored for cargo bikes & heavy utility loads
Ideal pairing for 1080Wh cell pack efficiency
Est. Range: 45 - 65 miles (Heavy load mixed)
Max Performance
50A Continuous
For 1000W - 1500W Motors
Built for custom e-trikes & high-torque DIY
Maximizes peak amp output without BMS tripping
Est. Range: 35 - 50 miles (Throttle-heavy riding)
Rider's Tech Note: Always make sure your e-bike controller's maximum current draw does not exceed the continuous rating of your chosen BMS. Running a 50A controller on a 30A BMS will trigger safety shut-offs under steep hill climbs.

Included 42V 5A Smart Fast Charger

Every pack ships with a dedicated 42V 5A high-current aluminum charger. Engineered with CC/CV dual-stage intelligent charging to safely replenish your 30Ah pack in roughly 6 hours without thermal stress.

Estimated 0–100% Charge Time (30Ah Pack)
Included 5A Fast Charger: ~6 Hours
Standard 2A Charger: ~15 Hours (60% Slower)
CC/CV Smart Cut-Off

Automatically transitions from constant current to trickle charge, shutting off precisely at 42.0V to eliminate overcharge risk.

Silent Active Fan Cooling

Heavy-duty aluminum alloy housing with a low-noise internal cooling fan keeps operating temperatures stable during high-amp sessions.

Status LED & Protections

Dual-color LED (Red = Charging, Green = Full/Standby) with built-in short-circuit, reverse polarity, and over-voltage fail-safes.

FAQ

Will this 36V 30Ah battery fit my electric bike, scooter, or custom DIY project?
It measures 300 × 190 × 90 mm and weighs about 7.0 kg (15.43 lbs). Before ordering, grab a tape measure and double-check your frame compartment, deck space, or mounting rack. Make sure your motor controller is rated for 36V setups so everything matches up smoothly.
How does the built-in Bluetooth BMS and mobile app work?
It features a smart JBD BMS with built-in Bluetooth. Just open the companion app on your phone to check individual cell voltage balance, view real-time current draw, track temperature, or remotely toggle the charge and discharge lines without pulling apart your build.
What is the metal casing made of, and is it actually waterproof?
The outer shell is built from rugged, one-piece stamped sheet metal with an anti-rust powder-coated finish. Inside, we pack high-density shock-absorbing foam and heavy waterproof potting adhesive around the cells. It easily handles rainy rides and rough trail vibrations, though you shouldn't submerge it entirely in water.
How long does it take to charge this 30Ah battery from empty to full?
We include a dedicated 42V 5A smart fast charger right in the box. Because it pumps out 5 amps, it cuts your total charging time down to roughly 6 hours—saving you hours compared to standard 2A chargers that take over 14 hours.
What kind of warranty support do you provide if something goes wrong?
Every battery comes with a 2-year limited manufacturer warranty. If you run into technical snags, balancing questions, or charging issues, our support team is backed by real engineers ready to help you sort it out fast.

Built-To-Order & Shipping Process

1

Fresh Built-To-Order

Every battery pack is custom built directly upon your order rather than pulled from sitting warehouse shelf stock. This guarantees maximum fresh chemical cycle life, zero capacity degradation, and optimal cell health from day one.

2

Authentic Cells & Full Test

We source original grade-A Samsung cells straight from official distributors per order. Once assembled, every pack undergoes a full charge and discharge test cycle to verify capacity, BMS balance, and thermal safety before final packing.

Door-To-Door Freight

Packs pass Hong Kong customs battery safety inspection and ship direct to your door via FedEx/UPS (US/CA) or DPD/DHL (EU). Delivery typically takes 15–20 business days. All import duties, taxes, and door-step delivery are fully covered.
