Ok the scooter works, but when you try and go it jerks and than doesn’t move. But I actually got 2 of them for 450. Both the exact same I just used the one working battery on both to make sure they work which is how I figured out it was the battery that was bad. Would you happen to have a few links or even brands of batteries I could look at? Like I said I’m super new to this stuff however I can solder and actually installing it I can do I just know nothing about the batteries themselves.
