If you use your Mobius in very hot conditions with external power, for example as a dash cam, you should consider replacing the battery with a Super Capacitor. A Super Capacitor enables the Mobius to correctly save the last recording when external power is removed. A fully charged Super capacitor has enough energy to keep the Mobius (Real Time Clock) running for several days with out external power connected. It only takes a few minutes to fully charge the Super capacitor.
