Core Specs: 72V Nominal Voltage | 20Ah Rated Capacity (1440Wh) | 80 Original Samsung INR21700-50G Cells (20S4P) System Rating: Smart JBD Bluetooth BMS with 30A, 40A, or 60A continuous discharge options (up to 180A peak burst) Compatibility: Suitable for 1000W, 1500W, 2000W, 2500W, and 3000W brushless DC hub motors and mid-drive motors Charging: Includes 84V 5A fast smart charger in aluminum housing; full recharge in 4 to 5 hours Key Hardware & Performance Features Authentic Samsung 21700 50G Grade-A Lithium-Ion Cells Engineered with 80 genuine Samsung 50G 21700 cells arranged in a 20-series 4-parallel matrix. These high-density lithium chemistry cells provide consistent high-amperage discharge, minimal voltage sag under heavy throttle acceleration, and long cycle life exceeding 800 charge cycles before significant capacity decay. Smart JBD Bluetooth BMS with Real-Time Smartphone Telemetry Integrated JBD Bluetooth battery management system pairs directly with iOS and Android devices via the Xiaoxiang / Smart BMS companion app. Riders can monitor individual cell delta voltages, pack thermals, cycle count, state of charge (SoC), and remotely toggle the discharge MOSFET switch for battery diagnostics and electrical theft prevention. Epoxy Plate Internal Short-Circuit Isolation & Weatherproof Casing Individual battery cell clusters are insulated and rigidized with flame-retardant epoxy composite barrier boards to prevent abrasion, mechanical puncture, and cell short circuits. The outer shell features tough blue PVC heat-shrink wrap fortified with top waterproof sealant against outdoor trail spray, mud, and light rain. Factory Plug-and-Play Connectors with Zero Sketchy Adapters Eliminate loose connections and melted wiring harness adapters with factory-soldered high-current discharge plugs. Choose from genuine XT90 anti-spark connectors, high-current QS8 terminals, or Anderson Powerpole connectors soldered with heat-resistant copper silicone wiring.

A: This 72V battery is compatible with 72V hub motors, mid-drive conversion systems, and custom electric motorcycle setups rated between 1000W and 3000W. Popular setups include QS Motor hub motors (QS205, QS273), NB Power kits, CYC X1 Pro Gen 3/4 mid-drives, and tuned Bafang M620 Ultra drivetrains matched with appropriate 72V brushless motor controllers. Q: How long does a full recharge cycle take? A: A complete zero-to-full recharge takes approximately 4 to 5 hours using the included 84V 5A smart fast charger. The 5A charging current safely distributes across the 4P parallel bank (1.25A per Samsung 21700 50G cell), ensuring rapid turnaround time without thermal stress or cycle degradation. Q: What estimated range will this pack provide per charge? A: With a 1440Wh total capacity, riders typically achieve between 20 and 45 miles (32 to 72 km) under pure throttle mode depending on the selected BMS discharge profile and speed. When pedaling on moderate pedal assist (PAS), range extends to 40 to 75 miles (64 to 120 km) based on a 175 lb (80 kg) rider on paved terrain. Q: How do I know if this battery fits inside my bike frame triangle? A: Measure your interior frame triangle against the pack dimensions: 280 mm (11.02 in) upper hypotenuse slope, 220 mm (8.66 in) bottom base, 175 mm (6.89 in) upright vertical height, and 90 mm (3.54 in) width. Prepare a cardboard template with these measurements to test clearance against down tubes, top tubes, and rear suspension shock reservoirs.
