13S10P Battery Configuration
The battery pack consists of 13 series groups, with 10 cells connected in parallel in each group.
13S × 10P = 130 cells
Using 3.7V 5000mAh cells:
- Total cells: 13 × 10 = 130 cells
- Nominal voltage: 13 × 3.6V = 46.8V
- Maximum charging voltage: 13 × 4.2V = 54.6V
- Parallel capacity: 10 × 5Ah = 50Ah
- Nominal energy: 46.8V × 50Ah = 2,340Wh
- Total energy: Approximately 2.34kWh
3C Lithium-Ion Configuration
The cells are specified as 3C-rated. The complete pack’s actual continuous and peak current capability should be determined according to the selected BMS and complete electrical and thermal design.
Key factors include:
- BMS continuous and peak current rating
- Cell discharge specifications
- Nickel/copper interconnection design
- Wire gauge
- Connector rating
- Thermal management
- Operating temperature
