Description
Power Pack 3.7V 18000mAh 1S9P 1C Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 3.7V 18000mAh 1S9P 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 18Ah capacity.
This battery pack is assembled using nine 18650 NMC lithium-ion cells connected in a 1S9P configuration. The parallel configuration increases the total capacity while maintaining the nominal voltage at 3.7V. An integrated 1S 5A BMS provides essential protection for the battery during charging and discharging.
It is suitable for portable electronics, LED systems, IoT devices, monitoring equipment, backup power systems, robotics, instrumentation, and custom electronic applications.

1S9P Battery Configuration
The 1S9P configuration consists of nine 18650 cells connected in parallel:
- 1 series group (1S)
- 9 cells connected in parallel (9P)
- Each cell: 3.7V, 2000mAh
- Total voltage: 3.7V nominal
- Total capacity: 18,000mAh / 18Ah
- Maximum charging voltage: 4.2V
- Energy capacity: approximately 66.6Wh
1C Lithium-Ion Configuration
Each 18650 cell has a capacity of 2000mAh.
2000mAh × 9 cells = 18,000mAh
Therefore:
Theoretical 1C pack current = 18Ah × 1C = 18A
The 5A BMS rating is the BMS current/protection specification. It should not automatically be treated as the guaranteed continuous discharge capability of the complete battery pack. Actual current capability depends on the cells, BMS, wiring, connectors, interconnections, and thermal management.
