Third, it is true that most of my charging is from my solar panel (120 watts). Most of our snow camping tends to be in Utah and the Sierra, so we usually get lots of sun. But assuming that I go with lithium batteries, I will want to make sure that the software in the battery prevents charging when it is below 32 degrees.
My Victron MPPT solar controller will stop charging if the battery is below a configured voltage. A $30 battery temperature sensor is required to do this.
My switch to a single 100 Ah LifePO4 has worked out great. With my 225w of solar, I have NEVER charged it up with anything but solar in 2 extended summers of ramblin'. Also, my old body can lift it. :)
