And just for the sake of wondering.... for temps that cold, could some sort of heat pad, blanket or bag not be used to keep the lith's warm enough to function properly? (I'm picturing a Domino's pizza delivery electric warmer bag) Or, perhaps, would moving your batt's inside your camper living space. Obviously if you go with the SiO2, your good to go. But for those with Lith's already, are there options if they are occasionally stuck in temps that cold?
Folks are either moving them inside to the heated/ cooled area or adding warming pads underneath them. You might have to take that into account and possibly add a battery for the warming pad.
I insulated the front compartment as bet as possible, added a 1/2" thick rubber mat under the batteries to get them off the metal floor and added a heat duct to the end of the duct work that ended right above the batteries. If it gets down into the teens then I'll open the heat source to the compartment. I can see cell temps on all 20 individual cells to see if warmer temp is needed.
