Hello,
ok, the cells are ICR18650W2 and they are connected as follows:
4 blocks in series and each block has three cells in parallel for a total of 12 cells. At each step there is a cable connected to the PCB I guess for monitoring the voltage so, there is a red cable at the main plus, orange cable at the next negative-plus, white cable at the next negative-plus, blue cable at the next and finally the black cable at negative followed by the thermal fuse. All the cables go to the PCB.
Then from the PCB there are 8 pins for outside. I have test the voltage but it´s nearly empty so now my doubt is find out the way to connect charge voltage at the pack:
A) Should I connect DC voltage between main plus and main negative at cells or should I do it at outside pins? I don´t know the function of each pin...
B) Which voltage should I supply at those cables? The battery says DC 14.6V 6000mAH and the charger from the laptop 20Vdc 6A... so I guess I should supply 20Vdc 6A
C) The battery charger plug for the laptop has 4 pins, do you think those 20V are going directly to the battery pack?
