I would like to get your thoughts on weather I should make my battery enclosure lid out of 6mm aluminium, or 10mm Polycarbonate. I already have both available so cost isnt an issue. I am going to use 2x 6s 30Ah Tattu lipos, and my only concern is weather I will need to get heat away from the enclosure. How warm are your batteries getting? My ESC will be water cooled, so no worries there.
