1S4P Battery Configuration
This battery pack contains 4 × 18650 NMC cells arranged in a 1S4P configuration.
- 1S: One cell group
- 4P: Four cells connected in parallel
- Total cells: 4 cells
- Nominal voltage: 3.7V
- Capacity: 2000mAh × 4 = 8000mAh / 8Ah
- Maximum charge voltage: 4.2V
- Energy capacity: 3.7V × 8Ah = 29.6Wh
1C Lithium-Ion Configuration
The theoretical 1C current is:
8Ah × 1C = 8A
The 8A theoretical 1C current is separate from the 5A BMS rating. The BMS rating represents the BMS current/protection specification and does not by itself guarantee a continuous 10A battery output.
Actual operating current depends on the cells, BMS, wiring, connectors, temperature, and complete battery-pack design.
BMS Protection
The integrated 1S 5A BMS helps protect the battery pack against common operating conditions, including:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell imbalance
Connector & Wire
