Description
Power Pack LiFePO₄ 2S 6.4V 45000mAh 2S3P 3C With BMS 10A Discharge LFP Battery Pack
The Power Pack LiFePO₄ 2S 6.4V 45000mAh 2S3P 3C LFP Battery Pack is a rechargeable lithium iron phosphate battery designed for applications requiring stable voltage, high capacity, safety, and reliable long-term performance.
This battery uses a 2S3P configuration with 6 LiFePO₄ cells. To achieve the specified 45Ah capacity, the pack uses approximately 15Ah cells, with three cells connected in parallel in each series group.
The integrated 10A LiFePO₄ BMS provides essential protection against overcharge, over-discharge, over-current, and short-circuit conditions.
Key Features
- LiFePO₄ (Lithium Iron Phosphate) chemistry
- 6.4V nominal voltage
- 45Ah / 45,000mAh capacity
- 2S3P configuration
- 6 cells total
- 3C-rated cells
- Theoretical 3C current: 135A
- 10A BMS included
- High thermal and chemical stability
- Long cycle life
- Rechargeable battery design
- Suitable for custom power applications
2S3P Battery Configuration
The battery is assembled using 2 series groups and 3 cells in parallel:
- 2S = 2 × 3.2V = 6.4V nominal
- 3P = 3 × 15Ah = 45Ah
- Total cells = 2 × 3 = 6 cells
- Energy = 6.4V × 45Ah = 288Wh
3C LFP Configuration
The cells are specified for 3C discharge.
- Pack capacity: 45Ah
- 1C theoretical current: 45A
- 3C theoretical current: 135A
Important: 135A is the theoretical 3C cell-level calculation. It does not mean the completed battery can continuously deliver 135A. Actual discharge capability depends on the 10A BMS, cells, busbars, wiring, connectors, and thermal management.
BMS Protection
The integrated 10A LiFePO₄ BMS helps protect the battery against:
- Overcharge
- Over-discharge
