Description
Power Pack 7.4V 2000mAh 2S1P 1C BMS 2A Lithium-Ion Rechargeable NMC Battery Pack
The Power Pack 7.4V 2000mAh 2S1P 1C BMS 2A Lithium-Ion Rechargeable NMC Battery Pack is a compact and rechargeable lithium-ion battery designed for portable electronic devices, equipment, DIY projects, backup systems, and other applications requiring a reliable 7.4V power source.
The battery pack uses 18650 NMC lithium-ion cells arranged in a 2S1P configuration, providing a nominal voltage of 7.4V and a capacity of 2000mAh (2Ah). A 2S 2A BMS provides protection against overcharge, over-discharge, over-current, and short circuit.
2S1P Configuration
This battery uses a 2S1P configuration:
- 2S = 2 cells connected in series
- 1P = 1 cell in each parallel group
- Cell voltage = 3.7V nominal
- Pack voltage = 3.7V × 2 = 7.4V
- Full-charge voltage = 4.2V × 2 = 8.4V
- Capacity = 2000mAh
The series connection increases the voltage while the capacity remains 2000mAh.
2S 2A BMS Protection
The integrated 2S 2A BMS helps protect the battery pack during operation and charging.
Protection functions may include:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Battery safety protection
The BMS current rating should be matched with the actual application’s continuous and peak current requirements.
Charging
For safe charging, use a charger designed specifically for a 2S NMC lithium-ion battery pack.
- Nominal battery voltage: 7.4V
- Maximum charging voltage: 8.4V
