So I grabbed one from a neighbor who was tossing it and a hoverboard out for being “broken”

Both had some wear but were in good shape overall.
I put the hoverboard battery on the DMM and it would show a quick 9V then drop to 3-5. It’s a 36V 4.4aH battery (lith-ion).

The scooter has two 12V 5aH batteries.

both showed between 13-14V

the motor has a 24v label on it.

does this sound like a controller?

I noticed the handbrake has a second switch and wire going into the body which I assume is a cutoff to the motor (since these aren’t fit for drifting).
Before I tear it all apart and trace power does anyone have any suggestions?

Shouldn’t 26V be enough to turn the motor?


The LED on the body light up as Dow the power switch

I ran the motor fine from my DC bench supply.

I tried bypassing the CB reset to see if that would work but all it did was power the “on switch”.

I’m thinking the main controller might be bad, though I can hear the relays click when twisting the throttle.
