I use LI in computers and cell phones. I have seen a low temperature warning on a cell phone that I left in my car overnight.
Do tell us what works for you.
I'll never have LI in my RV unless I have heated storage in the winter. or a low temperature chemistry is available in the 200 to 400 amp-hour capacity. That is extremely unlikely.
Don: The Relion RB100-LT specifically designed to charge normally at lower ambient temperaures (-4F / -20C) - they use some of the charging power to self-heat, so that they can accept charge at a normal rate below 32F/0C. There's no chemistry involved, it's just a LiFePO4 battery that heats itself. I have 2 of them, bought last year, and they function as designed. They weren't cheap (C$1800/each) but they are worth every cent.
