LiFePO4 and Lithium-ion Battery NCM/LFP Inductive Active Balancing Module 2S 1.2A
The LiFePO4 and Lithium-ion Battery 2S Inductive Active Balancing Module is designed for series-connected LiFePO4 and NCM lithium-ion battery packs. It uses inductive energy transfer technology to move energy between adjacent cells, helping reduce voltage differences and maintain more consistent cell voltages during charging and discharging. Unlike passive balancing circuits, it transfers energy between cells rather than simply dissipating excess energy as heat.
The module automatically monitors the voltage difference between adjacent cells and activates balancing when the difference reaches its operating threshold. It is suitable for energy storage systems, solar power projects, portable power equipment, and custom battery pack assemblies. It does not require an external power supply because it uses energy from the connected battery pack. A compatible lithium battery protection BMS is required for safe operation.
Features:
- Supports LiFePO4 and NCM lithium battery chemistries.
- Inductive energy-transfer balancing technology.
- Automatic adjacent-cell voltage monitoring.
- Transfers energy between cells to reduce voltage differences.
- Operates automatically according to cell voltage differences.
- Does not require an external power supply.
- Protective coating on the circuit board.
