BMS INSIDE power tool batteries has balancing leads PERMANENTLY connected to cells, you cannot disconnect those leads
those balancing leads connect to chip on BMS,
when you connect string whatever 11S, 12S cells you also connect those leads and chip to your EPLUS boards, how hard it is to understand it.
my conversion shows ONLY 11S cells in series , nothing more plus 2 pairs of wires from 2 different cells.
only way to use of power tool batteries is to disconnect any wires from cells.
it does not really matter what communicate with what.
so you say during discharge there is no any monitoring of cells inside power tool pack,????
open the pack and FOR SURE there are wires connected to each cell individually
dont forget that you must connected wires from 2 cells to upper Eplus BMS board
isolate those cells completely !!!
