My chair is so weird, I can charge it all day and night, but it still say not charged. Or I can run it almost dead, and it charge full just over night. I charged it all day, and all night, went dead after 2 miles. A few days ago I went 6 miles.
It kind of feels like the breaks come on while driving sometimes. Other times it feels like something comes loose and my chair comes to a dead stop.
I can't do too much to it because I'm trying to get a new chair.
