This is all too new for me. Could you also recommend a good semi cheap charger for a 6 cell pack of these???? Do you need a different charger for the higher voltage li po batteries?? What do ya do when there is no leads coming from the batteries??
The "C" rating is the mAh of the battery divided by 1000 multiplied by that # (20C, 30C, etc.) and is the amperage that battery can output, whether it be max or continuous.
Each "S" is a cell,with each cell being 3.7 volts, so 1S is 3.7 volts, 2S is 7.4 volts, etc.
The charge rate is the same thing as output "C"'s, except for how fast, or at what amperage you can charge it.
The small set of wires is for a balancer, I believe, which makes sure all the cells receive the same charge, and that one is not being over- or under-charged.
