72V 45Ah Heavy-Duty Battery Swap Pack is a swappable LiFePO4 traction pack engineered for battery-exchange operations. The 72V 45Ah pack is the heavy-duty tier of the swap range, built for loaded cargo tricycles and high-power e-motorcycles that draw sustained current on gradients. It delivers 3.46 kWh of nominal energy at 76.8V (72V class) in a pack weighing approximately 30 kg, dimensioned to fit standard swap-dock bays so a rider can exchange a depleted unit for a charged one in seconds.
Cell & BMS Technology
The pack uses grade-A prismatic LiFePO4 cells in a 24S1P configuration. A smart BMS provides cell-level voltage monitoring, multi-point temperature sensing, active balancing, over-charge and over-discharge protection, short-circuit protection and current limiting. Communication runs over CAN / RS485 / UART, Bluetooth optional, allowing the swap cabinet and vehicle controller to read SOC, SOH, cycle count and fault history for billing, diagnostics and fleet management.
Safety & Cycle Life
LiFePO4 chemistry removes the thermal-runaway risk profile associated with nickel-based chemistries and delivers more than 6,000 cycles at 80% depth of discharge, which supports several years of service in high-utilisation fleets. The BMS keeps operation inside a -20C to +60C window, and the enclosure is sealed to IP67 against rain, dust and wash-down.
Charging
Standard charge voltage is 87.6V with a maximum continuous charge current of 45A, giving a full charge in approximately 2.5 hours from empty. The BMS accepts CC-CV charging from swap-station chargers and supports parallel rack charging. Alternative fast-charge profiles can be supplied on request.
Mechanical & Enclosure
The pack is housed in a reinforced aluminium case with shock-absorbing mounts case with an integrated carry handle and a latch and guide-rail interface. Overall dimensions are 340 x 210 x 220 mm. A reinforced, vibration-tested variant is available for two- and three-wheelers operating on unpaved roads.
Typical Use Cases
Specified for cargo tricycles, passenger e-rickshaws and heavy delivery motorcycles in markets where a single pack must carry a full day of loaded operation with high current demand.
Customisation
Voltage, capacity, case dimensions, connector type, communication protocol and branding (labels, silk-screen and case colour) can all be customised for OEM and fleet programmes. Customisation on standard shells requires no new tooling; new tooling is quoted separately.
Every unit is 100% capacity-tested and balance-tested before shipment. Compliance target standards: UN38.3, IEC 62619, CE and RoHS. Warranty: 3 years (5 years optional).
