On this 52v electric scooter the key switch LED voltmeter displays 57.4v
After holding the power button on, it turns on but the LCD shows the voltage decreasing rapidly until it shuts down.
It is a Nanrobot D4 dual motor scooter and has 2 different voltmeters...the LCD meter is on the key switch and the other one is on the throttle/mode/odometer/power button.
The battery cell groups measure 4.1v each, all 14 of them. Also, if the BMS was faulty, the LCD voltage would decrease along with the voltage on the LED.
It seems like there is a big power drain within one of the speed controllers (it has 2 controllers and 2 motors)
If any of you have a better idea about this maybe you can chime in. Thanks.
