Duster - great stuff, thanks!

I've been searching a bit and apparently my balancer is similar to HYPERION EOS LBA6. I was looking at the diagram on what harness to use for a 2S and it doesn't quite add up (or perhaps I simply don't get it). I have attached an image of the 2S wiring diagram (see below). It shows a 2S which only has a total of 3 wires? (where as my Thunder Power has 2 + 4). Any idea how the wiring diagram for my thunder power battery would look like?

Another thing. The balancer's output connection has like 8 legs. Are they simply auto deteced some how? (is it fixed? do they charge? etc. Slightly confusing ).

Anyway - appreciate your time! Thanks!
