I rode mine all last winter in temps down to -30 C! Like all batteries, super cold temps will affect battery life a bit, but I've been super happy with the Hangover. It has a USB C charger, and the light still runs while it's plugged in. I haven't done it but in theory I guess you could bring a small battery pack along as back up and charge it on the go as well.
