## Description

Quickly equalizes cells in Li-ion, LiFePO4 and other 3S chemistries, through active balancing with energy transfer between cells, without heat dissipation. Provides up to 1.2A of balancing current for differences greater than 0.2V, operates at 2-4.5V per cell and connects easily via XH-2.54 4P connector.
The module for active balance between Lithium cells that allows the equalization of the cells in the 3S type battery packs (3 in series) with a total voltage of 12.6VDC.
The difference between this module and other modules that balance passively (discharge cells through heat), the module with active balance does not produce heat but transfers energy directly between cells. This allows equalization with a current of up to 1.2A without generating heat. It is compatible with any batteries that have a voltage per cell between 2 and 4.5VDC, from Lithium-Ion cells to LiFePo4 and others.
