Very low temperatures do not affect a battery’s life as long as a MoonBike is switched on (in the ON position). The battery box is actually heated and provides protection against the cold in temperatures down to -25°C (-13°F).
When you are not using your MoonBike, however, we recommend avoiding exposing its battery to low temperatures. When not in use, a battery should be stored at 20 to 80% of its capacity and recharged at least once every three months.
