I have one of these http://www.bikes4you.ie/scooters/twiste ... -48v-6inch
(do not remember 800W or 1000W, but I know what 36V). So I left it in garage (all time was ~ +15C) in winter time, but now, in spring, it won't go normal. I charged a couple times, but it's go slow, checked with tester, full charged battery is 39V, but after 10 m drops to 35V and after 20m drops to 32V, so, I think, battery dead? Or with maybe there is any possibility to renew with good charger, because last year everything was ok (scoter is ~100km mileage).
If I need to change batteries, maybe someone could recommend what to buy, I don't want spent a lot money, but do not want change batteries each season
Thanks for help
