Description
Power Pack 7.4V 14000mAh 2S7P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 7.4V 14000mAh 2S7P 1C BMS 20A Lithium-Ion Rechargeable NMC Battery Pack is a high-capacity rechargeable battery solution designed for portable electronics, robotics, CCTV systems, IoT devices, industrial equipment, backup power applications, and other custom electronic products.
This battery pack is built using 18650 NMC lithium-ion cells in a 2S7P configuration, providing 7.4V nominal voltage and 14000mAh (14Ah) capacity. With approximately 103.6Wh of energy, it provides extended operating time for applications requiring a compact and rechargeable lithium battery.
The pack includes a 2S 20A BMS (Battery Management System) for protection against overcharge, over-discharge, over-current, and short-circuit conditions.
Battery Configuration
The battery pack uses a 2S7P configuration:
- 2S = 2 groups connected in series
- 7P = 7 cells connected in parallel in each group
- Total cells: 2 × 7 = 14 × 18650 cells
- Cell capacity: 2000mAh
- Total capacity: 7 × 2000mAh = 14000mAh (14Ah)
- Nominal voltage: 2 × 3.7V = 7.4V
- Maximum charge voltage: 2 × 4.2V = 8.4V
BMS Protection
The integrated 2S 20A BMS helps protect the battery during charging and discharging.
Protection Functions
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage protection
- Battery safety monitoring
Note: The 20A BMS rating is the BMS protection/current rating and does not by itself guarantee 20A continuous output from the complete battery pack.
Charging
Use a dedicated 8.4V Li-ion/NMC charger for this battery pack.
- Nominal Voltage: 7.4V
- Maximum Charge Voltage: 8.4V
- Recommended Charger: 8.4V NMC/Li-ion charger
Always use a charger compatible with a 2S lithium-ion battery pack.
