@ PM: your best bet would be to get a
balance board and adapter for your charger.
I made a "universal" adapter for my hyperion based 8pin charger. I can plug certain taps right into it, or it fits the myriad balance adapter boards out there. Basically I used a hyperion 8pin male plug (into charger) connected to some 0.1" headers.
I got the two 4 pin headers from an old computer part actually. I unsoldered them, and then re attached to a spare blank circuit board I got from Ratshack way back when for making led light harnesses. Very handy.
