The thermometer icon always on indicates that the battery temperature has reached 50 C. It doesnt sound like much but you can feel it. I just updated the firmware and when it was done updating the unit turned itself off and now wont turn back on.
I have only charged it one.
When charging the battery light flashes red. I have only charged it one. When all lights remain lit the Ninebot is fully charged. Many seasoned e-scooter veterans have been here before.
