Description
Power Pack 14.8V 14000mAh 4S7P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 14.8V 14000mAh 4S7P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery designed for portable electronics, robotics, industrial equipment, backup power systems, and custom applications requiring a dependable 14.8V power source.
This battery pack uses 18650 NMC lithium-ion cells arranged in a 4S7P configuration, providing 14.8V nominal voltage and 14000mAh (14Ah) capacity. The integrated 4S 20A BMS helps provide protection during charging and discharging.
4S7P Configuration
The battery uses a 4S7P configuration with a total of 28 cells:
- 4S = 4 cell groups connected in series
- 7P = 7 cells connected in parallel in each group
- Total cells = 4 × 7 = 28 cells
- Cell capacity = 2000mAh
- Parallel group capacity = 2000mAh × 7 = 14000mAh
- Nominal pack voltage = 3.7V × 4 = 14.8V
- Maximum charge voltage = 4.2V × 4 = 16.8V
- Energy capacity = 14.8V × 14Ah = 207.2Wh
The 4S configuration provides the 14.8V nominal voltage, while the 7P configuration increases the capacity to 14Ah.
4S 20A BMS Protection
The battery pack is equipped with a 4S 20A BMS to help protect the battery during charging and discharging.
Typical protection functions include:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Charging protection
- Discharging protection
The actual continuous current capability depends on the selected cells, BMS, wiring, connectors and complete pack construction.
