172 -Begin the connection with the negative of the battery: the "V-" of the first BMS Logic 18 is connected to "B-", then the first cell (C1) of the battery is connected, then the second (C2), etc. The “V-“ of the next BMS Logic 18 is connected to the C18 of the previous BMS Logic 18. If not all inputs of the cells are used, then the remaining inputs are connected to the cell with the most potential.
