If you live in an area with harsh winters, your battery will degrade faster than usual. Do you want to a frame which is going to outlast an obsolete vehicle?
cold weather causes the battery to self-discharge at a higher than normal rate, not degrade or become damaged. but i would be happy to upgrade my pack, all of which are designed to be swapped out easily and even quickly enough for re-charge by swap in some models, when the next quantum leap in electrolyte chemistry comes along.
Opposite is true for leaf sans cooling in hot climates…
