I don’t know if I’m right here in the e-forum. Have the e-scooter Denver de001. Suddenly the power became weaker and after charging the light didn’t even light up in the display. I’ve already screwed up and measured by the plugged-off battery. Are 32.8 volts. The charger delivers 42.3, but it’s the same green so it should be full. Wanted to unload the battery and switched three halogen headlights with 3x 20 watts (60 watts) in series. But there was nothing there. the same attempt with the charger which gives me two amps. Here the test setup worked. Then I connected the charger directly to the plug from the battery but on the scooter side. The display then works again. And also the lighting. Thus I do not assume from a loose plug in the area of the steering rod. I also checked the motor. Did the wheel have to set in motion at the low power that the charger brings? And nu n my question about the pictures. What is this free plug that comes from the controller right in the picture2. (Test plug?) What does the comment on the voltage 30 +/- 1 volt mean? Has any of you ever opened this battery to see and also measure how many cells are broken? What should such a battery cost new? I’m curious about the answers thank you
