2S10P Battery Configuration
The battery pack contains 20 × 18650 NMC cells arranged in a 2S10P configuration.
- 2S: 2 cell groups connected in series
- 10P: 10 cells connected in parallel in each group
- Nominal voltage: 3.7V × 2 = 7.4V
- Capacity: 2000mAh × 10 = 20000mAh
- Total cells: 2 × 10 = 20 cells
- Maximum charge voltage: 8.4V
- Energy capacity: 7.4V × 20Ah = 148Wh
1C Lithium-Ion Configuration
The theoretical 1C current is:
20Ah × 1C = 20A
The 20A theoretical 1C current should not automatically be treated as a guaranteed continuous 20A output. Actual allowable current depends on the cells, BMS, wiring, connectors, thermal conditions, and complete battery-pack design.
BMS Protection
The integrated 2S 20A BMS helps protect the battery pack against common fault conditions, including:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell imbalance
