Description
BAK 20S 72V 45000mAh (45Ah) 20S9P 3C Lithium-Ion Rechargeable Battery Pack
The BAK 20S 72V 45000mAh (45Ah) 20S9P 3C Lithium-Ion Rechargeable Battery Pack is a high-capacity energy solution designed for electric mobility, industrial equipment, robotics, and custom battery applications. With a 72V nominal voltage and 45Ah capacity, this battery pack provides approximately 3.24 kWh of nominal energy, making it suitable for applications that require extended operating range and reliable power delivery.
Built in a 20S9P configuration, the pack combines 20 series-connected cell groups with 9 cells connected in parallel in each group. This configuration increases the overall battery capacity while maintaining the required high-voltage output for 72V-class electric systems.
Based on the specified 3C discharge rating, a 45Ah battery pack has a theoretical discharge capability of approximately 135A. Actual continuous current capability depends on the specific BAK cell model, BMS rating, thermal management, wiring, and overall pack design.
