Kane it seems that there is lots of protection for the top and base of lipo batteries, but only a fire resistant material for the sides ? so that will be vunerable to peircing and propably made from the thinnest metal possible to save weight, would that be acceptable.
Also the top and bottom of the lipos depends on the orientation of the robot which can change very
fast ! the robot could be damaged on its side of the lipos and then the robot thrown onto its side.
