Hi Folks, I'm pretty new to the solar world and wondering if anyone has any thoughts on how to keep my two 125ah agm batteries warm in the winter here in Minnesota. My tiny house is only heated when I'm there occasionally in the winter. Outside temps can reach -25 fahrenheit and I have freezing concerns. I have thought about using a battery warming pad it would just sit on. Would that work? Or a heater that wraps around the battery?
Any thoughts are much appreciated!
