There is a good reason to make separating the battery illegal. The heavy duty shrink wrap is for insulation as well as holding the batteries together. If you've dissected one of these "sub C" style of battery packs you'll find that the the cells are arranged with half of the positive terminals "up" and half of them "down" so it isn't hard to create a short circuit creating a "loop" between 2 or more batteries. Allowing that shrink wrap to be removed creates the need to have a standard as to what constitutes appropriate re-insulation thus putting additional demands on the inspectors.

I did notice in the Cascade/Olympic pits on Fri at least one minibot go by that had a clear wrap which made me think it wasn't a legal battery.
