For what it's worth (and it's pretty poor), here is a battery warmer I made for the LifePO4's for central Ohio, in an outhouse.
(2) 10x20 17v 120v plant warmer mats (no foam padding).
(1) Amazon temp controller that we also have in the coop.
3/4" foam board, 1" foam board, a full roll of foil tape.
The wood battery shelf has 1" foam under it, then the shelf 2x12, then 2 layers of pole-building bubble
Kinda made a wire mess.. :/
wrap, then warmer mats, then batteries.
2 layers of foam board all the way around.
Temp controller set for 40.
Charge & Temp Controller probes are on TOP of the batteries.
Temps here dip to -10 overnight (the worse ever was 5 days never reaching 10degrees.
