Description
Power Pack LiFePO₄ 12S 36V 75000mAh 3C Discharge LFP Battery Pack
The Power Pack LiFePO₄ 12S 36V 75000mAh 3C Discharge LFP Battery Pack is a high-capacity rechargeable lithium iron phosphate battery designed for applications requiring reliable energy storage, high discharge capability, and long service life.
This battery uses LiFePO₄ (LFP) chemistry with a 12S configuration, providing a 38.4V nominal voltage and approximately 43.2V maximum charging voltage. With a specified 75Ah capacity, the pack delivers approximately 2880Wh (2.88kWh) of nominal energy.
The 3C discharge specification gives a theoretical maximum discharge current of up to 225A, subject to the actual cells, BMS, wiring, connectors, and thermal design.

12S Battery Configuration
A 12S LFP battery consists of 12 series-connected cell groups.
- Series configuration: 12S
- Nominal cell voltage: 3.2V
- Nominal pack voltage: 12 × 3.2V = 38.4V
- Maximum charge voltage: 12 × 3.6V = 43.2V
- Required pack capacity: 75Ah
The exact parallel configuration (P) depends on the Ah rating of the individual cells.
For example:
- 6Ah cells → approximately 12P gives 72Ah
- 6.25Ah cells → 12P gives 75Ah
- 7.5Ah cells → 10P gives 75Ah
- 15Ah cells → 5P gives 75Ah
- 25Ah cells → 3P gives 75Ah
- 75Ah cells → 1P gives 75Ah
Therefore, P cannot be fixed from 75Ah alone without knowing the individual cell capacity.
3C Discharge
The theoretical 3C current for a 75Ah pack is:
75Ah × 3C = 225A
This does not automatically mean the complete battery can continuously deliver 225A. Actual continuous discharge depends on:
- Cell discharge rating
- BMS current rating
- Busbars/nickel connections
- Cable size
- Connector rating
- Battery temperature
- Thermal management
BMS Protection
A suitable 12S LiFePO₄ BMS can provide:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Cell balancing
- Temperature protection
- Low-temperature charging protection where supported
The BMS should be selected according to the application’s required continuous and peak current.
