Description
Power Pack 3.7V 12000mAh 1S6P 1C Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 3.7V 12000mAh 1S6P 1C BMS 5A Lithium-Ion Rechargeable NMC Battery Pack is a compact, high-capacity rechargeable battery pack designed for applications requiring a 3.7V nominal power source with 12Ah capacity.
Built using six 18650 NMC lithium-ion cells connected in 1S6P configuration, this battery pack provides increased capacity while maintaining a single-cell voltage level. The integrated 1S 5A BMS (Battery Management System) provides essential protection against overcharge, over-discharge, short circuit, and overcurrent conditions.
This 3.7V 12Ah lithium-ion battery pack is suitable for portable electronics, LED systems, IoT devices, backup power, electronics projects, medical equipment, monitoring systems, and other low-voltage applications.

1S6P Battery Configuration
The 1S6P configuration consists of:
- 1 series group (1S)
- 6 cells connected in parallel (6P)
- Each cell: 3.7V, 2000mAh
- Total voltage: 3.7V nominal
- Total capacity: 12,000mAh / 12Ah
- Maximum charging voltage: 4.2V
- Total energy: approximately 44.4Wh
1C Lithium-Ion Configuration
With a 1C-rated 2000mAh cell:
2000mAh × 6 parallel cells = 12000mAh
Therefore:
Theoretical 1C pack current = 12Ah × 1C = 12A
The 5A BMS rating is the BMS current/protection specification and should not be interpreted as a guaranteed continuous 5A discharge capability of the complete battery pack. Actual allowable current depends on the cells, BMS, wiring, connectors, nickel interconnections, and thermal conditions.
BMS Protection
The integrated 1S 5A BMS is intended to provide protection for the battery pack against common electrical fault conditions, including:
- Overcharge protection
- Over-discharge protection
- Overcurrent protection
- Short-circuit protection
- Battery protection during normal operation
The BMS helps improve battery safety and supports reliable operation when the pack is used with a compatible load and charger.
