I doubt you will do any good with trickle charging at cold temps. LFP is too efficient and there is litlle self heating, so this will not work.
Probably need to use LA or roll the dice. An expensive mistake if you lose. Even heating pads need a fossile fuel source in cold country with LFP powering a home. A duct from a heated home will also work but you need to keep that home warm and power the duct fan. Not fun if you have to leave the home for an emergency.
