Am doing some initial research into getting a cargo bike with an e-assist battery. How does the battery perform in cold (LOW) temperatures for winter commuting? Specifically wondering how the battery does in low temperatures as well as when a bike is fully loaded with groceries in cold/wet conditions. Is it more sluggish? Is there anything special one has to do to the battery to protect it in cold/wet winter conditions?

(will cross-post this in utility thread as well)

I feel that the battery might not have as much power, or the system seems to use more power in the winter (Maine winters). The Cycle Analyst shows using about ~3/4 AH more than in warmer weather for the same commute.

The only thing that I do differently with mine is I make it a point to bring my LiFePo4 battery inside when not in use.
