    Range extender

    Posted by Jds on Mar 14th 2023

    This went on a 2019 Orbea Gain. It seems to do the job for which it is designed. There is no way of telling the state of charge of this battery in the Mahle app even though there is supposed to be. The idiot light on the range extender just gives the gross state of charge the same as the internal battery. Maybe Mahle will get their act sorted out for the app. This charges the internal battery and the internal battery drives the motor.
