Description
Power Pack 7.4V 16000mAh 2S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 7.4V 16000mAh 2S8P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery pack designed for applications that require reliable 7.4V power with extended operating time. It is suitable for portable electronics, robotics, CCTV systems, IoT equipment, industrial devices, backup systems, and custom electronic applications.
The battery pack is assembled using 18650 NMC lithium-ion cells in a 2S8P configuration. It provides a 7.4V nominal voltage, 16000mAh (16Ah) capacity, and approximately 118.4Wh energy capacity.
A 2S 20A BMS is included to help protect the battery from overcharge, over-discharge, over-current, and short-circuit conditions.
Battery Configuration
This battery uses a 2S8P configuration:
- 2S = 2 cell groups connected in series
- 8P = 8 cells connected in parallel in each group
- Total cells: 2 × 8 = 16 × 18650 cells
- Cell capacity: 2000mAh
- Pack capacity: 8 × 2000mAh = 16000mAh (16Ah)
- Nominal voltage: 2 × 3.7V = 7.4V
- Maximum charge voltage: 2 × 4.2V = 8.4V
BMS Protection
The integrated 2S 20A BMS provides protection during charging and discharging.
Protection Functions
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage protection
- Battery safety monitoring
Important: A 20A BMS rating does not automatically mean the complete battery pack is rated for 20A continuous discharge. Actual output capability depends on the selected cells, BMS design, wiring, connectors, temperature, and application.
Charging
Use a dedicated 8.4V NMC/Li-ion charger for charging this battery pack.
