Description
Power Pack 11.1V 16000mAh 3S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 11.1V 16000mAh 3S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery designed for portable electronics, robotics, industrial equipment, backup systems, and other applications requiring a dependable 11.1V power source.
This battery pack uses 18650 NMC lithium-ion cells in a 3S8P configuration, providing 11.1V nominal voltage and 16000mAh (16Ah) capacity. The integrated 3S 20A BMS helps protect the battery from overcharge, over-discharge, over-current, and short-circuit conditions.
3S8P Configuration
This battery uses a 3S8P configuration with a total of 24 cells.
- 3S = 3 cell groups connected in series
- 8P = 8 cells connected in parallel in each group
- Total cells = 3 × 8 = 24 cells
- Cell capacity = 2000mAh
- Parallel group capacity = 2000mAh × 8 = 16000mAh
- Nominal voltage = 3.7V × 3 = 11.1V
- Maximum charge voltage = 4.2V × 3 = 12.6V
- Energy capacity = 11.1V × 16Ah = 177.6Wh
The 3S arrangement provides the required voltage, while the 8P arrangement increases the battery capacity.
3S 20A BMS Protection
The battery pack includes a 3S 20A BMS for battery protection and monitoring.
Typical protection functions include:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Charging protection
- Discharging protection
The actual continuous current capability depends on the cells, BMS, wiring, connectors and overall pack design.
