Description
Power Pack LiFePO₄ 3S 9.6V 45000mAh 3S3P 3C With BMS LFP Battery Pack
The Power Pack LiFePO₄ 3S 9.6V 45000mAh 3S3P 3C With BMS is a rechargeable Lithium Iron Phosphate (LiFePO₄/LFP) battery pack designed for applications requiring high capacity, stable voltage, reliable power delivery, and long service life.
This battery pack uses 9 LiFePO₄ cells arranged in a 3S3P configuration. To achieve the specified 45Ah capacity, the pack uses approximately 15Ah cells. It provides 9.6V nominal voltage, 45Ah (45,000mAh) capacity, and 432Wh nominal energy.
The integrated 3S LiFePO₄ BMS provides essential battery protection. With a 3C cell rating, the theoretical discharge capability is approximately 135A. Actual continuous discharge depends on the selected cells, BMS, wiring, connectors, and thermal management.

3S3P Battery Configuration
The battery pack contains 9 LiFePO₄ cells connected in a 3S3P configuration:
- 3 cells in series (3S) → 9.6V nominal
- 3 cells in parallel (3P) → 45Ah capacity
- Total cells: 3 × 3 = 9 cells
- Cell capacity: Approximately 15Ah
- Nominal energy: 9.6V × 45Ah = 432Wh
3C LiFePO₄ Configuration
For a 45Ah battery:
1C = 45A
3C = 45Ah × 3 = 135A theoretical
The 135A figure is a theoretical cell-based calculation. Actual continuous output depends on the cell discharge capability, BMS current rating, wiring, connectors and thermal conditions.
BMS Protection
The integrated 3S LiFePO₄ BMS helps protect the battery against:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell voltage imbalance
- Abnormal operating conditions
The BMS current rating should be selected according to the actual load and application requirements.
