I just bought a brand new sealed in the box scooter that sat in a guys garage for a few years schwinn s500 scooter but found the batteries were stone cold dead and will not take a charge. So I used my old batteries from my old 500s scooter.
As soon as I get the scooter rolling down the road it just cuts out and as soon as I turn it of and on again it takes off fast and than dies again.
The charger says the batteries are charged? The reason I got this scooter is my last one was doing the same thing.
I also had a razor 300 scooter that did the same thing. I changed out the controller,fuse,brake switch and even the motor. Finally I tossed the thing in the trash. Now I am on my second Schwinn with the same problem.
Any Ideas? I am going to buy new batteries tomorrow.
