3S10P Battery Configuration
The battery pack consists of 30 × 18650 NMC cells arranged in a 3S10P configuration.
- 3S: 3 groups connected in series
- 10P: 10 cells connected in parallel per group
- Total Cells: 3 × 10 = 30 cells
- Cell Capacity: 2000mAh
- Pack Capacity: 10 × 2000mAh = 20000mAh (20Ah)
- Nominal Voltage: 3 × 3.7V = 11.1V
- Maximum Charge Voltage: 3 × 4.2V = 12.6V
- Energy Capacity: 11.1V × 20Ah = 222Wh
1C Lithium-Ion Configuration
The pack has a capacity of 20Ah and the cells are rated at 1C.
Theoretical 1C Current = 20Ah × 1C = 20A
The 20A BMS rating should not automatically be treated as the guaranteed continuous discharge capability of the battery. Actual current capability depends on cell specifications, BMS design, wiring, connectors, interconnections and thermal management.
