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?
