Super Turbo 800 on Lithium batteries

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.

  1. Nice job.

    I just bought a Super Turbo 800 and I believe the lead acid batteries add a lot of extra weight. So I am looking to do a LIPO Battery conversion to help reduce the weight and hopefully pick up speed. One question for you, now that you have had it running for awhile would you still choose the same batteries?

  2. If you’re looking at a range of about 6 miles each day I would definitely recommend the same LIPOs because that’s a good range where they won’t get too low and the drop in voltage towards the end isn’t noticeable. With lipos when the green light goes off while you’re at full throttle that means you’ve only got about 1/3rd of the battery left. I honestly thing the battery that the manufacturer sales is a good one, It’s just a lot of battery and you pay for it all whereas the 8 AH is just about the right capacity for me each day.

  3. Excellent advice, tnahks-I have learned to be more and more sensitive to the C ratings. Usually, the higher C rating batteries have lower internal resistance, and this translates into performance in the air.The down side of this is that you should match your C rating to your usage.If you have a 3 cell 2200ma pack that has a 20C rating, and replace it with an identical pack with a 45C rating, then you will probably see an increase in perfomance.If your model only draws 20 amps average, both packs are really safe, and well within thier limits. The problem that some batterys have is that their chemistry is designed to be used close to these C ratings, and the 45C battery my not perform consistantly if you only use it at a 10C rate. This is just like a Corvette with a 427 being used for 20mph trips, the motors never gets the workout it needs, and then won’t perform when needed because it is full of carbon-Batteries are the same way, I have seen 45C packs only last 50 cylcles, (or one year) when flying a plane around that only draws 10 amps.

  4. I’ve got a feeling you drove your petanrs crazy while growing up. You are very intelligent but it’s a crazy kind of intelligence . When I was a kid I made my own cheap and effective shotgun from a couple pieces of pipe so I drove my petanrs crazy too so I’m definitely not slamming you. I just wonder what other inventions you had while growing up LOL! It would be interesting to know. Keep on keeping on but be careful.

  5. Can you give me step by step instructions on how to convert my 800 Elite to Lithium Batteries. Thanks.

  6. Here’s a quick list of what’s needed to convert to lithium batteries. Feel free to ask any questions if any part needs clarification.
