My hesitation with Lithium batteries isn't based on fire. They also have a minimum temperature they should be exposed too. I'm sure it varies but the ones I've looked at had an absolute minimum temperature that was above what it often gets to on cold winter nights. If my camper is sitting outside all winter that would mean needing to unhook the batteries and bring them inside. With AGM or flooded batteries, as long as they are charged (and the solar will take care of that) there's no reason to unhook them and bring them inside during the winter.
True, but more of an issue with travel trailers where they are on the tongue. Mine are housed in passthrough storage with a furnace vent and a 200W heater that comes on if the passthrough temperature drops below 40F.
I just pulled a report for the last six months and the coldest reported battery temperature was 10C, or about 50F. Doesn’t look like the electric heater has ever been needed, and we’ve been below freezing many times.
