Description
Power Pack 7.4V 12000mAh 2S6P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 7.4V 12000mAh 2S6P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable lithium-ion battery designed for portable electronics, robotics, industrial equipment, backup power systems, CCTV, IoT devices, and custom applications.
This battery pack is assembled using 18650 NMC lithium-ion cells in a 2S6P configuration. It provides a nominal voltage of 7.4V and a capacity of 12000mAh (12Ah), delivering approximately 88.8Wh of energy.
The battery pack is equipped with a 2S 20A BMS (Battery Management System) to provide essential protection against overcharge, over-discharge, over-current, and short-circuit conditions.
Battery Configuration
The battery uses a 2S6P configuration:
- 2S = 2 cell groups connected in series
- 6P = 6 cells connected in parallel in each group
- Total cells: 2 × 6 = 12 × 18650 cells
- Cell capacity: 2000mAh
- Pack capacity: 6 × 2000mAh = 12000mAh (12Ah)
- Nominal voltage: 2 × 3.7V = 7.4V
- Maximum charging voltage: 2 × 4.2V = 8.4V
BMS Protection
The integrated 2S 20A BMS helps protect the battery pack during operation and charging.
Protection Functions
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage protection
- Battery safety monitoring
The 20A BMS rating does not automatically mean that the complete battery can continuously deliver 20A. Actual discharge capability depends on the cells, BMS design, wiring, connectors, thermal conditions, and application.
Charging
This battery pack requires a dedicated 8.4V lithium-ion/NMC charger.
Nominal Voltage: 7.4V
Maximum Charge Voltage: 8.4V
Always use a charger specifically designed for a 2S NMC/Li-ion battery pack.
