Hi there,
Some time ago i bought an electric skateboard from daibot, (aliexpress) and since they are no help at all, i hope some of you might know the issue.
I was dumb enough to drive trough the rain with the skateboard, and it actually had a lil bit of corrosion, at that point it would turn on, but had problems driving the motors. Now i was able to clean up the corrosion, and get it functioning again.
When i'm not riding it myself, or not too long at least it works fine. But it seems that when it draws too much power, it turns off.
I did some testing and measured the voltage across the battery while powering the motors, at first the voltage stays quite steady, but when the motors draw more load (holding the motors for testing purposes) everything turns off, and the battery will give a voltage of about 6 volts, before very slowly ramping back up (electronics won't turn on at that point). If i disconnect the battery the voltage rises right back up to about 24.5.
I've attached a picture of the electronics and as far as i could reach of the BMS, the battery is a 7S battery, using 18650cells.
