Stand-Up Scooter, what to buy? Please Help

[imorton]

Good day everyone, I want to buy a Stand-Up Scooter similar to the EVO, or the Super Turbo models.



My question is, I currently own a brand new 48v 15Ah LifePo4 battery (Sun-Thing from eBay) that I would like to use in a used/new stand-up scooter that I find. I see that I can buy these scooters in various models in 36v or 48v models and they advertise motors like 800w or 1000w. Naturally if I can find/buy a used 48v model, that would be best.

However, If I find/buy a 36v model, I guess I could change the controller to a 48v model for @ $40, but what about the stress on a 36v motor (by pumping 48v into it), is it gonna kill/overheat the motor it in short time?

The scooter will generally be used on relatively flat ground, but it will be pushing a 250 lb guy around…

PS: I see there's 36v 800w, 36v 1000w, and 48v 1000w models on the internet, what would best for me in relationship to speed, range, and reliability?

Thanks for any help, IAN.

I just remembered that my 48v 15Ah Lifepo4 pack (from Sun-Thing on eBay) can probably can only handle 2C (so 30amp peaks max) so I am limited to a 30amp controller on the scooter that I find. I wonder if it is better to get a 36v 800w model and push 48v through it.

Or should I try and find a 48v 1000w model and use my LifePo4 battery…?

Hmmm, questions, questions, decisions, decisions…

Maybe someone here with some experience can help? IAN.

I have an 800W EVO, a friend of mine got one as well, but then sold it to buy a registered 36V / 1000W version like the one you show.
Regarding your question above, I am afriaid the available space won't allow you to go for a 48V battery in a 36V e-scooter
(e-scooter frames are usually built "around" the pack and available space is very limited)
The original motors on both of these models are somehow reliable for the use u describe. (i burned mine for known reasons : long hills and wish to go for brushless)

The scooter will generally be used on relatively flat ground, but it will be pushing a 250 lb guy around…

I would suggest you to go ahead with a 48V 1000W version : you would have a good chance that your spare battery actually fit in there
Maybe you should check in my e-scooter topic below if I posted some speed/range numbers

Thanks for the reply.

I measured my battery, and it is 11" x 5" x 6"

If you could be kind, can you measure your battery box. The ones I saw would handle everything but the height. I would likely have to elevate the floorboard @1.5" by modifying the rim of the battery box.

Thanks a million.

I just picked up a good priced used scooter. The 48v 1000w EVO style or SVT 1000w XL Turbo model. I'll have to start measuring and modifying the battery box to put in the LifePo4 pack…

Any other tricks that I should know about?

IAN.

I think making your own stand up results in a much more capable end product.

Slip a 10t mac in a g4 kick bike and you have a 30mph+ capable machine with plenty of torque. I use 1/3 of the available power to hit 30mph too so a higher speed wind would go even faster.

Speed isn't everything of course. I think 30mph is fast enough on a stand up, your opinion may vary.

This bike pulls my kids to school in a trailer still on the low 1kw setting with ease.

On the 2kw+ setting it nearly smokes the front tire from a dead stop.

Too bad the rear drop out is only 65mm. I would prefer a rear drive but the front has worked out beautifully so far.

Total weight is pretty light with a 450whr em3v 9R 50v pack.
