So I got an S350 off of Craigslist for $40. The batteries were shot. That's fine with me. I've been riding electric scooters for over 10 years and have more batteries that I know what to do with.
So naturally I put in two batteries and installed a third one in the basket to run it at 36V.
I did take the scooter for a spin at 24V just so I could gauge the difference the third battery would make.
Usually a 24V scooter ran at 36V will take off like a shot, have improved hill climbing ability and top out at around 20-25mph.
The S350 takes off like a slug and then slowly gains speed until it gets to about 22mph. As for hill climbing, it doesn't climb hills any better than it did at 24V.
Anyone have any clues why it's behaving this way?
