Description
Power Pack LiFePO₄ 20S 64V 45Ah 20S3P 3C With BMS LFP Battery Pack
The Power Pack LiFePO₄ 20S 64V 45Ah 3C Battery Pack is a rechargeable lithium iron phosphate battery designed for compatible electric mobility systems, industrial equipment, and custom power applications. With a nominal voltage of 64V and a capacity of 45Ah, it delivers approximately 2,880Wh (2.88kWh) of energy.
Built using LiFePO₄ cells in a 20S3P configuration, this battery pack includes a Battery Management System (BMS) to help protect the cells during charging and discharging. Its specified 3C discharge rating corresponds to a theoretical discharge current of up to 135A, provided the cells and supporting components are rated for that load.
This battery is suitable for applications requiring high capacity, rechargeable power, and integrated battery protection.

3C Discharge Configuration
At a 3C discharge rate, the theoretical discharge current is:
45Ah × 3C = 135A
Actual continuous discharge capability depends on the cells, BMS current rating, wiring, connectors, cooling, and operating conditions. Ensure all components support the intended current before operating the battery at 135A.
BMS Protection
The included Battery Management System helps monitor and protect the battery pack. Depending on the selected BMS model, protection functions may include:
Cell overvoltage protection
Cell undervoltage protection
Overcurrent protection
Short-circuit protection
Temperature monitoring and protection, if supported
