	Lithium batteries are less tolerant of cold temps, and can be damaged if you attempt to charge them when too cold. It's better to find a cubby inside to protect them from marginally cold temps.

	That being said, I do use a Harbor Freight tongue box to hold a 200ah LiFePO4 battery. The BMS in the batteries should protect it from cold weather charging. I do have some foam (the packing foam from the battery's original packaging) under and partly surrounding the battery. So far, it has worked well. Also, you could find batteries that have a built-in heater to warm them in such situations. That does use some of the battery power, but does help with cold weather camping. Sometimes, there just isn't room inside so one has to adapt.
