- Maximum charge voltage: 43.2V
- Pack capacity: 135Ah
The exact parallel configuration depends on the selected cell capacity.
| Cell Capacity | Configuration | Pack Capacity |
|---|---|---|
| 5Ah | 12S27P | 135Ah |
| 7.5Ah | 12S18P | 135Ah |
| 15Ah | 12S9P | 135Ah |
| 27Ah | 12S5P | 135Ah |
| 45Ah | 12S3P | 135Ah |
| 67.5Ah | 12S2P | 135Ah |
| 135Ah | 12S1P | 135Ah |
3C Discharge Configuration
For a 135Ah battery:
135Ah × 3C = 405A
The 405A figure is the theoretical 3C discharge current. It should not automatically be treated as the continuous output capability of the complete battery pack.
Actual current capability depends on:
- LFP cell discharge rating
- BMS current rating
- Busbar design
- 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
For a high-capacity battery, the BMS should be selected according to the required continuous and peak current.
