My hoverboard will not charge the battery - the charger LED stays green. The battery is almost new, and charges fine when the charger is directly attached to it (the yellow connector). I ran the hoverboard untill battery voltage was around 39.5V, but it still wont charge. I have battery voltage at the mainboard where the battery connects, and charger voltage (41V) at the connector on the mainboard coming from the charger inlet. Somehow the voltage is not let through the mainboard to the battery. There are no error blinks on the mainboard (only nine when turned upside down) and the howerboard works just fine when riding it. It will not power up with only charger attached (battery disconnected). WIth battery and charger disconnected I have about 15V where the battery connects to the mainboard (and at the yellow battery connector towards the mainboard). When shorting the on/off switch this voltage drops slowly and rises again when the short is removed. Guess it is some of the capacitors holding charge. I have tried recalibrating without any change.
Any ideas on what causes this error? Any suspect mainboard components? I would really appreciate some advice!
I have pictures but did not see how to insert them, I will try and insert afterwards
