I understand your feelings on ROAR, just remember that if a sanctioning body will not back something then most likely it will die. Your average user does not need shells, the only people to really want something like this is racers that want to build packs. You may give Danny at SMC a pm and see if he has any clues on how to get shells. Your gonna have to buddy up to a battery distributor most likely to try and get access to them.
