Exactly, The battery pack has 17 pairs of wires going to board. 13 of them to monitor the cells voltages and 4 for the temperature. I cannot be sure but I assume if the voltage of one of the 13 cells is below a set point value the electronics will disable the charge. if even one of the cells is...

Tom, So each block of 8 cells is 2s4p which doubles the voltage and quadruples the mAh rating, correct? YES The 4 cell block is 2s2p which doubles the voltage/mAh. Is that right? NO, the 4 cell block is just 1P, one parallel of 4 cells. Paolo

madin88, I guess is not possible to buy the single board individually??

goodgnus there are 13 series of parallels of 4 cells. the 8 cells you see are 2 series of 4 parallels. If you pay close attention to the picture you'll see that 4 of them have the + in common and the other 4 have the - in common, in other words, they are in series.
