For the most part people call for tech support on the things they do no understand. I can usually walk then through things in about 5 minutes. There are so many ways to hook these units up it would be nearly impossible to cover them all in a manual with schematics. As far as charging with the card and battery packs that need balancing, its really not possible. The only thing I can
suggest is to take your balance plug to a charge jack on the side of the plane (like an Ernst charge jack if its a JR style) and then charge through the card for the main charging a use the balance plug on the side of the plane to connect your charger balance. Most of the time the balance plug is not a JR style. If it is a JR style, there are two ways to wire them so that confuses things. Also, connection to the board is a two conductor Deans so there is no way to connect the center tap.

A schematic gives you that warm fuzzy that you have connected things the way the manufacture intended. Another thing is charging through the board dose not talk about how this is handled since our A123 / LiPo battery also have a balance tap to consider. Please help the newbie!
