    If you do use LiFePo4 batteries, there are some made for cold service. The KiloVault CHLX series, for example, have internal heating pads, and will stop charging and use the charging current to heat the battery until it's warm enough to accept a charge. I guess you could to this yourself with a thermostat placed inside the battery pack, and sending solar power to the heating pad until it's warm enough, then send the power to the battery.

    Probably just easier to use AGM as others have pointed out.

    The Listed Charge/Discharge cycles look impressive, But have yet to be seen if the ratings are for real.

    AGM will keep itself warm with a trickle charge.
