Agree Chris, for OR this really can't be the case. OTOH in 1:12 this is still a nightmare! The Nats this year I dumped with matched EP 4600 cells and a 5,5 with low ratio and zero timing - and that was on the first charge!
Going to a 1:12 WC or EC is in my opinion a waste of time unless you are sponsored... this is OTOH great about OR!
But again, 5 cells will not be good for the majority of the racers. It will drive costs up.
@Lowie: You forgot the "Battery Nurse" suitcase which isn't cheap either...
