I just bought a cellpro 10s off here. All good and I know my way round it as I already own a 4s.
My question is, as I understand it, I can charge 2 x 3s packs together providing they are pretty close state of charge etc. What balance board, boards or leads do I need to do this. All my batteries have standard jst-xh balance connectors on. I do have one board with the charger already but it says it's for charging one battery at a time only on it. It's this one
Thanks for any help.
