However for higher levels of competition Cars can be "teched" its not hard to imaging if you had a 4400mah battery and put 4800mah into it after a 8 minute run. Maybe there had been some tampering. and I'm sure you could also argue that a 7000mah battery shoved in a 4400mah case would provide a better voltage through a run. But again, can be cycled after a run to determine the battery capacity.
