Description
Power Pack LiFePO₄ 2S 6.4V 75000mAh 2S5P 3C With BMS LFP Battery Pack
The Power Pack LiFePO₄ 2S 6.4V 75000mAh 2S5P 3C LFP Battery Pack is a high-capacity rechargeable lithium iron phosphate battery designed for applications requiring stable voltage, high energy storage, safety, and long service life.
This battery uses a 2S5P configuration with 10 LiFePO₄ cells. To achieve the specified 75Ah capacity, each cell is approximately 15Ah. The pack provides 6.4V nominal voltage and 480Wh energy capacity.
A compatible 2S LiFePO₄ BMS is included to help protect the battery against overcharge, over-discharge, over-current, and short-circuit conditions.
Key Features
- LiFePO₄ (Lithium Iron Phosphate) chemistry
- 6.4V nominal voltage
- 75Ah / 75,000mAh capacity
- 2S5P configuration
- 10 cells total
- 3C-rated cell configuration
- Theoretical 3C current: 225A
- BMS included
- High thermal and chemical stability
- Long cycle life
- Rechargeable battery design
- Suitable for custom power applications
2S5P Battery Configuration
The battery is assembled using 2 cells/groups in series and 5 cells in parallel:
- 2S = 2 × 3.2V = 6.4V nominal
- 5P = 5 × 15Ah = 75Ah
- Total cells = 2 × 5 = 10 cells
- Energy = 6.4V × 75Ah = 480Wh
3C LFP Configuration
The battery uses cells specified for 3C discharge.
- Pack capacity: 75Ah
- 1C theoretical current: 75A
- 3C theoretical current: 225A
Important: 225A is the theoretical cell-level 3C calculation. It is not a guaranteed continuous output of the finished pack. Actual discharge capability depends on the cells, BMS rating, busbars, wiring, connectors, and thermal management.
BMS Protection
The integrated 2S LiFePO₄ BMS helps protect the battery against:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell imbalance, depending on BMS design
The BMS must be correctly matched and wired for a 2S LiFePO₄ battery.
