4S 6A Active Equalizer Balancer, a high-efficiency module designed to redistribute energy between individual cells in a 4-cell lithium battery pack. Unlike passive balancers that bleed off excess energy as heat, this module uses capacitive energy transfer to move charge from high-voltage cells to lower-voltage ones.
Core Specifications
Battery Compatibility: Works with Li-ion (3.7V nominal) and LiFePO4 (3.2V nominal) battery packs.
Balance Current: Supports a maximum balancing current of 6A. The actual current depends on the voltage difference between cells (e.g., ~6A at a 1V difference, ~1.2A at 0.2V).
Working Voltage: Typically operates between 2.5V and 4.4V per cell.
Protection: Features automatic low-voltage shutdown if a cell drops below 2.5V to prevent over-discharging.
