If you look at this picture you can see it has the 2mm balance plug joined to one of the 4mm plugs on the black bridge wire. You shouldn't have to change anything when you use a trackpower harness or the hyperion adapter azjc linked to. Nothing complicated about balancing one of theses packs, as long as you've conected them in series it doesn't even matter which end of the bridge wire you put the 2mm balance plug on, because it will still measure the same cell. Personally I'd choose these over the maxamps, unless you really need the extra mah.
