Default RE: LIPO

Hey, no problem chummer.

Maybe this will help even more.

Attached is a quick & dirty Paint image of a 3S2P LiPo. You can see the three sets of 2P configuration. + to + and - to -. These are the black connections.

Then, each parallel set is put in series: + to - and - to +. These are the red connections.

Sounds like it would short, but it won't unless you also connect the outside two. (blue)

Blue is where the output of the pack is. The connections points are the little black dots.

The balance taps would come out from each red connection, and the balancer would just compare the voltage of each set of parallel cells. If they are not even, the balancer will discharge the high one a bit at a time, continuously, until they're even.

NiCd and NiMH cells kind of self balance as they charge, just by being connected together in series. For some reason, lithium doesn't do this.
