Thus, in general the battery is at room temps and will perform like normal... Now, if you leave the battery outside all day and all night, there
will be some loss of power/performance/penalties for doing that, how much depends on the temps and the size of the battery.... It is the way it is...

What he said.
I haven't noticed a difference. There may be lower range, but I haven't gone for that long of a ride. Power doesn't seem to be much different.
I charge in my garage. Not warm but not as bad as outside. Batteries generate heat when they run, so I haven't had any issues in the cold.

can anyone with e-bike winter experience speak to the issue of battery performance/life riding in extreme cold?
