I have two old SMD/Mugen style boxes(2x motors..) I have always used two nimh stickpacks, but was wondering how to use a lipo with them. Could I just use XT60 to Tamiya plug adapters? What size lipo - 3S or 4S? Or 2S per plug since a normal stick pack is like 7.2V?

I don't want to have to solder or rewire or otherwise do a bunch of fiddling. But if I could just buy an adapter and use lipos I already have (lots of 4S and 3S...) I'd consider it, instead of buying more stick packs.

Thanks.
