24v dc scooter...

[Matthew Jones]

THe e 300's I worked on had 100 watt motors. They were geared at 3 to 1 to acheive higher torque. But they might have changed.

Good luck

About..

Is it more like a moped than only electric, and how much are they?

yes it is like a wide skateboard but with two inflated 10" tires with steering wheel and this particular model has a seat. You can get one for 240-300 depending where you get it.

Hey don't go anywhere.. lol

Hey now you can't come in and suggest something then bolt. I started to follow your other posts from the tesla switch I think it was and I wanted to know more about the system you are talking about. You seem to have the knowledge I am looking for and I wanted to pick your brain about this.

Herer is the link for the scooter:

I'll draw up the schematic over the weekend and put it up for ya.

You'll put in on the scooter on the bench and tear it up a bit to figure out how your gonna put it all in. Like I said you gotta get the batterries. Thats the biggest expense besides the scooter. But you'll go from and average of 2.5 hours (Stock) to about 80 +- hours with the tesla switch mod.

I am doiong some tests on a solid state tesla switch. Maybe that would be easier to put in. But thats not functional yet.

I be close by.

It looks too tiny for me, plus I'm over the wait limit

[Jbignes5]

Sweet..

I'm game and waiting with baited breath for your schematic. I was thinking about the motor. Would it need any special kind or should I just go with the in hub I am designing?
oh and stock time is about 45 mins with the current batteries and motor setup. Not much in my opinion.

Edit: just got the delivery notification for the 28th for the scooter... Yeah!

Rofl!

Dude im 200 so it is just about maxed out lol!

The Tesla switch would be the ultimate in adding hours to your riding time. If you decide not to go with it, then maybe adding 2 more batteries and a switch to charge one set while drawing from the other, may be another viable option. You can also buy higher amp hour batteries for your scooter. I have also seen a video where someone used high amp hour Dewalt drill batteries in their setup. There are many options to consider, with price being the true deciding factor. Good Luck. Stealth

[Jbignes5]

yup

Yeah I'm leaning tword the Tesla switch. Just got to wait for the scooter. Should be here by tuesday! but I do think there are more option to be explored as I want to have generators on the hubs and an limited trickle charge solar option as well for when I leave it chained up at places that I go to. I'm gonna try to maximize this thing out for the size and really show off this communities ideas to the max.
The thing is the wheels are not that big hub wise so the generator will be small as well. But everything put together should net a good balance. After awhile I'm gonna move the motor to the wheel hub and eliminate the motor and chain to streamline it. Maybe a dual hub motor in the rear with dual front generator. But like I said I'll have to wait on that one for the moment till i get the scooter in hand to look at it and plan my way to the ultimate machine.
Till then feel free to keep suggesting options for us to explore!

Well I won't swear by this but I am pretty sure its right. BUT its setup to run continues. So what going to happen initially if you are not switching right away is current will flow heavy to one side. You may need to play with it to get it to your liking.

You can also take a smaller relay, a small coil and reed switch and make them resonate by putting them in to a triangle configuration. This isn't always reliable but you might give it a try. You can also do the same thing with a transistor but it really to fast to drive the relays.

I film a movie of it this afternoon.

[Jbignes5]

ok

Hmm How does that circuit relate to this system? I'm just trying to understand this setup and yours by comparrison.

That system isn't to great for efficiency. I have wired all the layouts that are out there. The one I posted will do the best job. Trust me.

Hey

Hey Mathew are you the same that commented or contributed to the panacea document on this subject?
I will trust your thoughts and experience on this.
Also it isn't clear but the output to the motor is off of the bridge right?
The batteries that come with the scooter are 2-12v wired in series to make 24v should I rewire them to fit the diagram?

If you want to put some oomph to that scooter, then check out this website where you can purchase a motor that will put some speed/torque to it. Burden Sales Surplus Center - Electric Motors, Gearmotors, Relays, Toggle Switches Stealth

Ya thats me. And I don't know it all or anything, that system just performed better then the other one. The other one being the one had pictures of.
Its also the one I have put on 2 scooters like yours.
