Ok I can see two cells being wired in parallel in each pack making a total of 3.7 volts, but as the previous packs illustrate per pics, they show 7.4 volts. Why? Seems no one has or can answer that one.
So the next question if you don't mind, since they are parallel in each pack (2 cells per pack) , what controls how much each cell charges, IN a pack of two cells? Since they are parallel as stated, I assume each pack only has one balance lead lead, right? Or does each pack have a pair of balance lead wires, one for each cell?
I never said their was a single small 4S pack like one of these, I said two packs that state they are 7.4 each, make 4S when in series. Not sure where that quote came from.
