Description
Power Pack 3.7V 14000mAh 1S7P 1C Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 3.7V 14000mAh 1S7P 1C BMS 5A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery solution designed for applications requiring a 3.7V nominal voltage and 14Ah capacity.
This battery pack uses seven 18650 NMC lithium-ion cells connected in a 1S7P configuration. The parallel configuration increases the overall capacity while maintaining the nominal pack voltage at 3.7V. An integrated 1S 5A BMS provides essential battery protection during charging and discharging.
It is suitable for portable electronics, LED lighting, IoT devices, monitoring equipment, backup power, robotics, instrumentation, and custom electronic applications.

1S7P Battery Configuration
The 1S7P configuration consists of seven 18650 cells connected in parallel:
- 1 series group (1S)
- 7 cells connected in parallel (7P)
- Each cell: 3.7V, 2000mAh
- Total voltage: 3.7V nominal
- Total capacity: 14,000mAh / 14Ah
- Maximum charging voltage: 4.2V
- Energy capacity: approximately 51.8Wh
1C Lithium-Ion Configuration
With each 18650 cell rated at 2000mAh and 1C:
2000mAh × 7 cells = 14,000mAh
Therefore:
Theoretical 1C pack current = 14Ah × 1C = 14A
The 5A BMS rating refers to the BMS current/protection specification. It does not automatically mean the complete battery pack can continuously deliver 5A. Actual continuous current capability depends on the cells, BMS, wiring, connectors, interconnections, and thermal management.
