Has anyone tried an ammonia system, like old RV refrigerators and commercial cooling systems use? The system has to be in a secure spot with a weak point (a fuse of sorts) that would allow the ammonia to dissipate away from any passengers in case of a wreck or other failures. I was thinking it could be built into the battery container to keep it secure while keeping the batteries cool. And all it takes is a bit of heat to make it work. I am a newb here and this is my first post And while I am learning much about battery systems to fine tune my electric golf cart, I had to put my 2 cents in on an angle that may have been overlooked.
