Description
Power Pack 7.4V 8000mAh 2S4P 1C BMS 10A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 7.4V 8000mAh 2S4P 1C BMS 10A Lithium-Ion Rechargeable NMC Battery Pack is a reliable rechargeable power solution designed for portable electronics, robotics, backup systems, lighting equipment, instruments, and custom applications.
This battery pack uses 18650 NMC Lithium-Ion cells arranged in a 2S4P configuration, providing 7.4V nominal voltage and 8000mAh capacity. An integrated 2S 10A BMS provides protection during charging and discharging.
Custom wire lengths and connector options can be provided according to application requirements.
Key Features
- 7.4V nominal voltage
- 8000mAh / 8Ah capacity
- 2S4P cell configuration
- NMC Lithium-Ion chemistry
- 18650 rechargeable cells
- 2S 10A BMS
- 1C cell discharge configuration
- 5mm DC Jack / 2-Pin JST 54mm
- Compact rechargeable power solution

2S4P Battery Configuration
The battery pack contains 8 × 18650 NMC cells arranged in a 2S4P configuration.
- 2S: 2 cell groups connected in series
- 4P: 4 cells connected in parallel in each group
- Nominal voltage: 3.7V × 2 = 7.4V
- Capacity: 2000mAh × 4 = 8000mAh
- Total cells: 2 × 4 = 8 cells
- Maximum charge voltage: 8.4V
- Energy capacity: 7.4V × 8Ah = 59.2Wh
1C Lithium-Ion Configuration
The theoretical 1C current is:
8Ah × 1C = 8A
The 8A theoretical 1C current is different from the 10A BMS rating. The BMS rating indicates the BMS current specification and does not automatically mean the battery should continuously deliver 10A. Actual operating current depends on the cells, BMS, wiring, connectors, thermal conditions, and application.
BMS Protection
The integrated 2S 10A BMS helps protect the battery pack against common operating faults such as:
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell imbalance
Connector & Wire
