How about another A123 question..

I have a set of 2s A123 packs that have just 3 wires coming out, the power leads and a single lead..  How can I hook these up to my Hitec X2, as it requires (For charging LIPo, LiFe and Li-ion packs) power leads, as well as a Balance plug.. is where a way for me to make an adapter that would essentially give me what I need without having to take the shrink wrap off of the packs, and completely rewiring it?

Thanks, Craig.
