How to charge/balance two TrakPower's

[BrianG]

Hmm, I was thinking you had two 2s TP packs (the ones in the cases). If you have that balancer and two 2s packs, you can use one balancer on both packs just like the diagrams on my lipo web page. Or, you can do the diagram they show in that pic, but that requires another balancer unit. If charging two 5s packs, you'd almost HAVE to charge them in parallel or you'd need a 10s capable charger if done in series.

Either way, you should still charge packs like this if they both have always been used together, seen the same number of cycles, have the same charge level, and seen the same usage.
