Hello, actually the charger does work: battery gets correctly charged ("EQ 049" code at the end of charge). I am using the scooter every day without problems. Instead the "fuel gauge" is frozen at "full bars" while the "estimated range" is set to "0". I will check according to your hint. Thanks. Kind regards

Hello Piotr, I own a Li+ 2012 Vx1, upgraded to Nissan Leaf batteries. The "fuel gauge" gets stuck in "full bars" while "est range" is "0". Vectrix Diagnostic GUI shows "red N/A" on the "charger firmware version" field (BMS, MC and ICM firmwares version appears ok). Actually the charger (Runke Gold 2.1) is properly working. Furthermore the combinations of brake levers/throttle/dashboard buttons (to activate other menus) are not working as well. Should I reinstall the "charger firmware"? Or should I reset the charger (by unplugging/replugging it)? Thanks. Regards.
