The battery equalizing is necessary for the not perfect matching between the elements that composes a battery pack. During the successive battery charging and discharging there is always a cell that has a capacity slightly different from the others and after multiple cycles is deeply discharged; this cell has a big probability to break.

In order to avoid this problem all the cells should be discharged individually with a particular circuit capable to individuate the end-of-discharge moment for each cell.

This hard "reset" for the cells clears the integral charge/discharge difference accumulated in several work cycles. The equalizer is connected at each cell in the pack and discharge with 6 different mosfets, up to 6 different cells.

The user can define the cut-off threshold for each cells, and the discharge current. The realistic values are 0.5V for the cut-off in a deep discharge and a current of 0.5A or similar.


1. Cut off voltage from 0 to 999mV per cell
2. Current from 0.1 to 1A per cell
3. Displaying of the individual cell voltage during the discharge
4. Up to 10 consecutive discharge cycles for better equalizing and charge removal

Like all the others instruments also the equalizer is powered with 12VDC supply.
