72V 20Ah High-Speed E-Motorcycle Battery is a traction battery pack for electric two- and three-wheelers. A high-rate 72V pack for e-motorcycles capable of 70-90 km/h, where continuous current demand and acceleration response drive the cell and BMS selection. It provides 1.54 kWh of nominal energy at 76.8V (72V class) and weighs approximately 12.5 kg, with mounting points, terminal layout and discharge curve matched to the customer's controller and chassis.
Cell & BMS Technology
The pack is built from grade-A prismatic LiFePO4 cells in a 24S1P configuration. The smart BMS manages cell balancing, over-charge and over-discharge protection, over-current and short-circuit protection, and temperature protection, and communicates over CAN / RS485 / UART. Parameters such as continuous current limit, low-voltage cut-off and SOC curve are configured at the factory to suit the vehicle controller.
Safety & Cycle Life
LiFePO4 cells deliver more than 6,000 cycles at 80% depth of discharge and a service life several times that of lead-acid or typical NMC packs, with no thermal-runaway propagation behaviour. The enclosure is sealed to IP67 and the pack operates between -20C and +60C, covering hot, humid and monsoon conditions in South and Southeast Asia, the Middle East and Africa.
Charging
Standard charge voltage is 87.6V with a maximum continuous charge current of 20A, giving a full charge in approximately 1.5 hours from empty. The BMS accepts CC-CV charging from the supplied charger or an on-board charger and supports opportunity charging during breaks in service.
Mechanical & Enclosure
The pack uses a aluminium alloy case with anti-vibration mounts case with integrated mounting brackets, an anti-theft key lock option and a removable carry handle for vehicles with detachable battery compartments. Dimensions are 270 x 170 x 180 mm.
Typical Use Cases
Applied to high-speed electric motorcycles, sport commuters and long-distance delivery bikes where controller current limits are set above 60A and sustained highway-speed running is required.
Customisation
Voltage, capacity, case shape, connector and terminal type, communication protocol, key lock and branding can be customised for OEM and distributor programmes. Battery management firmware parameters are set per vehicle model, and engineering drawings are supplied for approval before tooling or volume production.
Each pack is 100% capacity-tested and balance-tested before shipment. Compliance target standards: UN38.3, IEC 62619, CE and RoHS. Warranty: 2 years / 3 years optional.
