16S5P Battery Configuration
The battery is built in a 16S5P configuration:
- 16 cells/groups connected in series
- 5 cells connected in parallel per group
- Individual cell capacity: 3.75Ah
- Total cells: 16 × 5 = 80 cells
- Nominal cell voltage: 3.2V
- Pack nominal voltage: 16 × 3.2V = 51.2V
- Pack capacity: 3.75Ah × 5 = 18.75Ah
Important: The above calculation shows that a 16S5P pack using 3.75Ah cells would actually be 18.75Ah, not 75Ah.
For a 16S5P 75Ah pack, each cell would need to be:
75Ah ÷ 5P = 15Ah per cell
Therefore, the correct configuration for the product title is:
Correct 16S5P Configuration for 75Ah
- Cell capacity: 15Ah
- Parallel: 5P
- Series: 16S
- Total cells: 80
- Pack capacity: 15Ah × 5 = 75Ah
- Nominal voltage: 51.2V
- Energy: 51.2V × 75Ah = 3840Wh / 3.84kWh
3C Discharge Capability
For a 75Ah pack with 3C-rated cells:
75Ah × 3C = 225A theoretical current
Actual continuous discharge depends on the cell specification, BMS rating, busbars, wiring, connectors and thermal management.
BMS Protection
A suitable 16S LiFePO₄ BMS can provide:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell balancing
- Cell voltage monitoring
- Temperature protection when supported
For a 75Ah high-capacity battery, the BMS should be selected according to the required continuous and peak load.
Connector & Wire
The output terminals and cables can be customised according to the application.
Possible options include:
- High-current DC terminals
- XT90
- Anderson-style connectors
- M8/M10 battery terminals
- Custom power connectors
For high-current applications, the cable and terminal rating must match the actual load.
