I have 2 200 AH LifeBlue lifepo batteries. I ordered them with internal heating. I don't know if the batteries have activated the warming function or not. The coldest I've seen them via their Bluetooth Interface is at 47 to 54 F degrees this winter so far. Bear in mind d I haven't gone out camping yet and there's shore powered heat on in the TC. I have added 1 inch pink foam board around and under the batteries. I also have 1 inch foam board insulating from the compartment exterior door. My battery box has the back cut away for these larger batteries so they get exposure to warmer inside air. Seems to work well enough.
