Description
Power pack 11.1V 2000mAh 3S1P 1C BMS 6A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 11.1V 2000mAh (2Ah) 3S1P 1C Lithium-Ion Rechargeable NMC Battery Pack is a compact rechargeable battery solution designed for electronic and portable power applications.
The pack uses 3 × 18650 NMC Lithium-Ion cells connected in a 3S1P configuration, providing 11.1V nominal voltage and 2000mAh (2Ah) capacity. A 6A BMS is included to provide essential battery protection during charging and discharging.
With a 1C cell configuration, the theoretical cell-based discharge current is 2A. The installed 6A BMS does not mean the cells should continuously deliver 6A; the actual safe operating current depends on the cells and complete pack design.

3S1P Battery Configuration
The battery pack contains 3 × 18650 cells arranged as:
- 3 cells in series (3S) → 11.1V nominal
- 1 cell in parallel (1P) → 2Ah capacity
- Total cells: 3 × 1 = 3 cells
- Nominal energy: 11.1V × 2Ah = 22.2Wh
- Maximum charging voltage: 4.2V × 3 = 12.6V
1C Lithium-Ion Configuration
The theoretical 1C discharge current is:
2Ah × 1C = 2A
The 6A BMS rating is the protection/current rating of the BMS, not a guarantee that the battery can safely deliver 6A continuously. Actual continuous current should be determined by the 18650 cell specification, BMS, wiring, connectors and thermal conditions.
6A BMS Protection
The integrated 3S 6A BMS is designed to help protect the battery against:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell-related abnormal conditions
- Unsafe charging/discharging conditions
The BMS should be used within its specified operating limits.
