IMHO, I think that they will make every other battery a practice pack once they are legal everywhere.
sorry to gloat but they are already legal in the UK and have been for a while.
my suggestion is that if u get any ( matched or unmatched is to not charge over 6 amps as its not worth it.
secondly drop the pinion on the motor a tooth or too ( ie go smaller) as with the extra voltage you get more rpm.......
