so i got these 2 lipos they connect to the PCB and to the charger as follows but i want to combine the two to make them one circuit. and im more then lost. is this correct or am i gonna blow my self up? mabey you can fill in the blanks on the empty image? thanks.
My charger only has two pins, and is wired like this.
I don't know what your third pin does, but there is a difference between the "Common" on the PCB and "Ground." They are most definitely not the same, if that helps at all.
