I've already stated why around the 2mm mark is a sensible suggestion so no point me typing it out again. It used to be in the rules, and its worth Kane putting it back in the rules.

Everyone might be trying to cram in as much power and resilience as possible - but this isn't stopping that in the slightest? If the rules were to state that the base needed to be a certain stiffness and strength to help prevent lipo damage you would instantly be on the case saying thats too complicated to understand and who decides what thickness's of different materials are strong enough! Just keep it simple for everyone to understand!

If people are running with gaffa taped and exposed terminal's that you seem to imply, then they shouldnt be passes a tech check regardless of the battery type so that's not a valid point.
