I don't think I could survive at that temperature unless I had continuous utility power to heat both the battery and propane cylinders. In which case LFP would be fine.
If power went out, I think I could still make the night to roll out in the morning.
I can't imagine SiO2 retains all its rated energy at that level either.

it doesnt, at -20C it only has 80% of its original capacity, 60% at -30C, and at -40C/F it only has 40%.
