Ditto to Thomas, I don't ballance charge unless I am in the workshop, on the field I just top them up every third flight or so, some people top up whilst re-filling the tank on every flight as another alternative, but as Thomas said above they do not seem to be too bothered by being ballanced or not.

Anyone who has not ballanced charged a pack of A123's at any time, can they test the capacity and voltage of these packs and let us know? It would be very interesting.
