Can you convert S1000 to 48v without changing controller??

I have a S1000 and want to upgrade to 48v. Do I need to change the controller/Motor or will the stock ones handle the voltage?? Thanks

I read that the clutch mechanism will likely fail if you up the power on that scooter, not the controller.

I heard of someone running the stock controller at 48v on the old forum I think. Or maybe they were just running the motor at 48v with a different controller. In any case, I think a 6v increase would be a more cautious approach, while still being prepared and expecting the controller to fry. This would be going from 36v to 42v with an added 6v battery.

http://www.batteryspace.com carries a good 6v smart charger.

I have a stealth 1000 and I added another 12 volt battery and it has worked out great. I gained about 3-4 mph out of it. It was a dog before adding the battery, which I mounted behind the seat post in a small zipper bag which doesn't stand out as much as you would think. The only drawback is having to toggle the on switch in order to get it to "take". Most of the time with rapid switching It stays green after 5-10 seconds. I've had this set up since New Years with no problems. Go for it. Adds a new demention to the scoot.

Realistically, how fast do those things go? The Rad2Go E-36 scooter I have for my 13yr old son does ~22 mph easily with tons of torque for launches and hill climbs. It's rated at 800W but I hear that the S1000 runs slower even though it is supposedly 36V and 1000W.

Nukem.

The 1000w motor is better for reliability and torque. I'm running 60v through mine, and I'm not worried. I would be on a smaller motor. I'm not using the stock controller. I use the yk42-4. I had 48v on the stock controller though. Just flip the switch really fast for 3 seconds and then leave it on. That worked for me.

I bent my wheel, broke my trans, and blew my motor. Now I cry a lot.

CAUTION: I ran mine with 4x12V 18AH SLA batteries (Powersonic 12180) for about 20 miles total, four 5 mile rides, with no problem other than the "click-click-click" and having to turn it on and off. However, this morning it was more like "click-click-pop-sizzle" when trying to power up and now the controller doesn't work anymore.

I would recommend giving/selling the stock throttle and controller to the less fortunate and buying a 48V unit (which is now what I'm forced to do.) 42V would probably be ok, if the 48V pack was down a couple of volts I didn't get the start up problem at all.

I needed a 48V charger anyhow, so I think I'll buy one of the 48V ebike kits. I've been wanting to try out a hub motor anyways.

update/correction: my controller is fine. The fuse had a loose connection in the fuse holder, got hot, melted the fuse plastic as well as the fuse holder, and was making the pop/sizzle sounds mentioned above. I'd tap on the controller and could get the scooter to operate intermittently (actually I was shaking the fuse holder and making/breaking the bad contact.)

I sanded the fuse legs and reinstalled the fuse. Everything's working now, melted fuse/fuse holder and all.

I bought a LB37 48V controller from tncscooters.com for $35, guess I have a replacement if/when the controller does fail.

I am running 4x12V 18AH batteries in the battery pan, made a custom deck with a big hole in the middle for the batteries, and a plastic tub to cover the batteries. My range is more than double than the 3x10AH of the stock pack.

I upgraded a second S1000 (2007 model, dual disc brakes) to 48V. We ran into a little snag. When the batteries are fully charged (55V or so) the controller won't come on. No clicking, just silence.

The fix was to put a 100 ohm resistor inline with the battery. This drops the voltage enough to get the controller running. Then, short around the resistor before riding. The controller stays on and runs fine after that. I used some male/female terminals to break/reconnect the main power wire, and ran the resistor out the back of one terminal into the back of the other (if you can picture that.)

This would also be a good work-around to eliminate the click-click-click, power off, power on cycle on other scooters, I think.

We are going to install the LB-37 48V controller just to see what happens :P

My scooter has over 100 miles on 48V with no problems (since the melting fuse holder incident.) I regularly load about 350 lbs on the scooter, I'm really impressed at how the frame and suspension components are holding up. I'm pushing it way beyond the 240 lb. rider limit. I do try not to jump curbs and run over small animals.

I think we really lucked out to find those plastic boxes, they fit just right over the qty. 4 12180 powersonic batteries.
