Norway is not "those kind of temperatures". They get a lot of snow, and maybe -5C and that is all because Gulfstream (the reason Murmansk does not freeze, and it's much farther into Arctic). Otherwise they get it easy.

Now when you move just a bit off the sea, the continental climate kicks in, and you have weeks of -15 -- -20C.

On discharging lithium chemistries at those temperatures or "easily overcame with resistive" let me say that: you just don't know what you are talking about.
