Soo umm that can't be good...

So, I guess we have determined how warm the packs should be for pre-heating, but how warm should they be during the run? I am just wondering how cold is TOO cold? Now that I have the esc waterproofed I want to run this thing in the snow but I guess -20 is a bit cold for the batts.

Also, I saw somewhere that hardcases really do nothing to insulate the lipos and actually hurt the insulation more than anything? I am not going to run hardcase next time just because I hate not being able to keep an eye on the batts.
