After having my lead acid batteries sit over the winter and a failed attempt to use NIMH batteries, I wised up and tried running my Super Turbo 800 Electric Scooter running on LIPO Batteries. 8 AH 30 C Zippy lipos. This setup is not recommended and I would guess is not endorsed by the manufacturer but seems to work really well.
The capacity is 8 AH rather than the 12AH that come with the scooter from the factory but the voltage stays high the entire ride with lipos and your high voltage is a bit higher with lipos. Range is about 6-10 miles depending on wind and other factors. The cost for the lipos I purchased from hobby king was $150 or so. You’ll want a charger that is made to balance charge 5 cell lipos which may cost you another $100 or so from hobby king. I went ahead and got a charger that charges the two batteries at once so I could technically charge them both in under two hours.
The performance from these lipos is a high speed around 22 MPH but it was windy when I had the GPS on it last last. Bottom line is that even @ almost a full 42V (10s @4.2V per cell) the thing doesn’t go over the specs from superscooters of 20-25 MPH. It’s fine for me… I think 20-25 is just about right because it’s a nice safe speed. I just wish that it had a little more power to beat the wind. The gusts where I live slows the scooter down to maybe 13 MPH some days.
I’ve been using this setup for maybe 40 days now and the batteries seem to show no sign of failing (no balloon effect). The current draw is fairly low compared to what these batteries are capable of: they pull about 4C but the batteries can allow up to 30C burst.
