12S Battery Configuration
The battery uses a 12S configuration, meaning 12 cell groups are connected in series.
- Series: 12S
- Nominal cell voltage: 3.2V
- Nominal pack voltage: 38.4V
- Maximum charge voltage: 43.2V
- Required pack capacity: 90Ah
The exact parallel (P) configuration depends on the capacity of the individual LFP cells.
Examples:
| Cell Capacity | Approx. Configuration | Pack Capacity |
|---|---|---|
| 5Ah | 12S18P | 90Ah |
| 6Ah | 12S15P | 90Ah |
| 7.5Ah | 12S12P | 90Ah |
| 10Ah | 12S9P | 90Ah |
| 15Ah | 12S6P | 90Ah |
| 30Ah | 12S3P | 90Ah |
| 90Ah | 12S1P | 90Ah |
Therefore, the exact cell count should be finalized based on the selected cell capacity.
3C Discharge Configuration
For a 90Ah battery:
90Ah × 3C = 270A
The 270A figure is a theoretical 3C current. It should not automatically be treated as the continuous output capability of the complete battery.
Actual current capability depends on:
- LFP cell discharge rating
- BMS current rating
- Busbar/nickel-strip design
- Cable gauge
- Connector rating
- Pack 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-current 90Ah pack, the BMS should be selected according to the required continuous and peak load.
