Cold Weather Range Reduction - This much?

[VT_EE]

I’m in Alaska and lose 40-50% in the winter. Also up hill is double to triple. My commute is almost 1000 vertical feet down then back up. In the summer I typically see <100 Wh/mi to work and 500 Wh/mi home.

also as per the 110v in the cold. I don’t se no gain plugged into 110v until I’m <0F.

Is that 0F outside temp or actual battery pack temp? I've had it stop charging with 120V when it's gotten down in the teens overnight.

Outside temp, not sure how I could tell the battery temp. But after 11 hours outside at below 0F I imagine the battery would be that temp. last winter I only plugged in to 110 at work when it was <0F and once I figured out it didn’t make a difference I quit doing it.
