Description
Power Pack LiFePO₄ 23S 72V 135Ah 23S9P 3C With BMS LFP Battery Pack
The Power Pack LiFePO₄ 23S 72V 135Ah 3C Battery Pack with BMS is designed for compatible electric mobility, industrial equipment, and customized high-voltage power applications. Built using Lithium Iron Phosphate (LiFePO₄ or LFP) chemistry, this rechargeable battery pack offers high energy capacity and stable performance when operated according to the cell manufacturer’s specifications.
The 23S9P configuration contains 23 series groups, with nine cells connected in parallel per group, for a total of 207 cells. Assuming 15Ah cells, the pack provides a capacity of 135Ah and approximately 9,936Wh (9.936kWh) of nominal energy.
The included Battery Management System (BMS) helps monitor and protect the battery. Actual discharge capability depends on the cells, BMS rating, wiring, connectors, and thermal conditions.

Battery Configuration
This battery pack uses a 23S9P configuration:
23S: 23 cell groups connected in series.
9P: Nine 15Ah cells connected in parallel per group, assuming 15Ah cells.
Total cells: 23 × 9 = 207 cells.
Nominal voltage: 23 × 3.2V = 73.6V.
Capacity: 9 × 15Ah = 135Ah.
Nominal energy: 73.6V × 135Ah = 9,936Wh.
3C Discharge Configuration
At the specified 3C discharge rate:
\[ 135Ah \times 3C = 405A \]The theoretical discharge current is 405A. Actual continuous discharge capability must be confirmed against the selected cells’ discharge rating, BMS current limit, wiring, connectors, and thermal conditions. Do not operate the pack at 405A unless every component is rated for that current.
BMS Protection
The battery pack includes a Battery Management System (BMS). Depending on the selected model, available protection functions may include:
Overcharge protection
Over-discharge protection
Overcurrent protection
Short-circuit protection
Cell-voltage monitoring and balancing
Temperature protection, if supported
Important: Confirm the BMS current rating and supported protection features before operating the battery under high loads.
Connector & Wire
High-current output connector selected according to the application.
Cable gauge matched to the expected current and cable length.
Charging connection configured to suit the charger and BMS.
Custom connector and wiring options available upon confirmation.
