What do I need a battery cover for?
The regular working temperature of a battery is above 20 degrees Celsius. I the outside temperature is below an insulation of the battery helps keeping it warm . The self-heating of the battery while discharging will remain inside and lift the internal working temperature. This may increase your range.
Please note: If you park your bike in cold environment self-heating will not recognizably lift the internal temperature. To create the best effect make sure that the battery is always stored and charged in room temperature. Shortly before starting your ride put it onto your bike with cover on. So self-heating of the battery can be held inside and provide a superior internal temperature.
