## Description

Allows rapid cell equalization in 5S lithium packs up to 21V, through active balancing with direct energy transfer between cells, without heating as in passive solutions. Provides balancing current up to 1.2A to reduce voltage differences, works with 2-4.5V cells including Li-Ion and LiFePO4, easy connection via XH-2.54 6P connector.
The module for active balance between Lithium cells that allows the equalization of the cells in the 5S type battery packs (5 in series) with a total voltage of 21.0VDC.
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.
