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.
