Instead, I found only certain contacts connected only.
If i guess this correctly, you will have 1 wire connected to the plus and one to the negative, the other wires will be connected to what is effectively the battery bar between each of the others cells. So, when the discharger wants to check the voltage of each cell it does it in series, swapping the polarity of the wires to suit the cell it wants to monitor.
Have a look at the diagram, to check the status of cell A, use wires 1 and 2, to check cell B use wires 2 and 3, to check cell C use wires 3 and 4, etc..
So, i think thats why they don't need 12 wires, 2 to each cell, the computer chip programming sorts out the polarities and works it all out???
