Description
Power Pack 11.1V 8000mAh 3S4P 1C BMS 10A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 11.1V 8000mAh 3S4P 1C BMS 10A Lithium-Ion Rechargeable NMC Battery Pack is a compact and reliable rechargeable battery solution designed for robotics, RC vehicles, portable electronics, industrial equipment, backup power, LED systems, CCTV equipment, and custom electronic applications.
This battery pack uses NMC lithium-ion 18650 cells arranged in a 3S4P configuration, providing 11.1V nominal voltage and 8000mAh (8Ah) capacity. The pack is equipped with a 3S 10A BMS to provide protection during charging and discharging.
With approximately 88.8Wh of energy capacity, this battery pack is suitable for equipment requiring a higher-capacity 11.1V rechargeable power source.
3S4P Battery Configuration
The battery pack uses 12 individual 18650 cells arranged in a 3S4P configuration.
- 3 cells/groups connected in series
- 4 cells connected in parallel in each group
- Total cells: 3 × 4 = 12 cells
- Cell capacity: 2000mAh
- Pack capacity: 4 × 2000mAh = 8000mAh
- Nominal voltage: 3 × 3.7V = 11.1V
- Maximum charging voltage: 3 × 4.2V = 12.6V
- Nominal energy: 11.1V × 8Ah = 88.8Wh
The 3S4P configuration provides higher capacity than a 3S3P 6000mAh battery while maintaining the same 11.1V nominal voltage.
10A BMS Protection
The battery pack is equipped with a 3S 10A BMS designed to help protect the battery during normal charging and discharging.
Depending on the BMS design, protection functions may include:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Battery protection during charging and discharging
The 10A BMS rating should not be interpreted as the same as the cell’s 1C rating. The actual safe operating current depends on the cells, BMS, wiring, connectors and application.
1C Discharge Rating
The battery uses cells specified at approximately 1C discharge.
For an 8Ah battery:
8Ah × 1C = 8A theoretical current
The BMS is rated at 10A, but the battery should be operated within the limits of the complete pack design and cell manufacturer’s specifications.
12.6V Charging
This is a 3S NMC lithium-ion battery pack, therefore the maximum charging voltage is 12.6V.
Nominal Voltage: 11.1V
Maximum Charge Voltage: 12.6V
Use a suitable 12.6V CC/CV lithium-ion charger.
The charger current should be selected according to the battery cells, BMS and required charging time.
Compact Battery Design
The 3S4P configuration provides 8Ah capacity in a relatively compact battery pack. The pack can be supplied with different connectors, wire lengths and physical dimensions according to the application.
The standard configuration includes a 5mm DC jack / 2-pin JST 54mm connector arrangement and approximately 5cm wire length, with customized wiring available.
