Where to get controller for XM 4000li?

Xtreme has been very good about replacing things under warranty on my 4000li. I have owned it since January. How old is your 4000li and what happened to the controller????

Hi Celtics, I've been away from V for awhile. Sorry you're having troubles. I replaced the controller for my XM-3500 with a Kelly KBL225H1 it's good from 24 to 120v and is variable regen capable, also programmable. I like it and the regen brakes are nice since the XM brakes are so-so. I've prepared a list of the latest problems to pop up with my XM.
1. The brackets that hold the rear fender broke and I had to repair it by drilling a couple holes on each side and running zip ties up over the frame tubes and pulling them tight.

2. My ignition switch shorted out and is now useless. The (semi) easy fix for this is, take the nose piece off so you can get to the switch. Then disconnect the switch at the nearest connector and push the end that doesn't go to the switch down where you can reach it. If you connect those two wires the bike is now live. You could attach a toggle switch or whatever you like. That's you're new ignition switch. (On switch really I guess)

3. Left headlight about half brightness of right headlight. (Probably a faulty connection I'll have to track down)

4. Bike begins to wobble out of control if you take your hands off the handlebars.

5. Left bike for 8 months in Florida to come back to a dead pack. All cells need to be replaced. OUCH!

I still love the electric ride but feel like I was an unwitting guinea pig.
Product not quite ready for prime time. I have two XM-3500s one 5012km and one with 4289km.
One thing I don't quite understand, the 5000 controller should actually work better for you I would think. It's just putting out more wattage. I am very much an amateur, maybe some more knowledgeable will comment. Sorry you are having a bad time, they are really fun when they are not acting up. Oh, one more thing, When you do get going, check the voltage on the farthest forward cell on the left (where the main + hooks up) I was recently riding and noticed my range was dropping off too fast. I smelled the smell of toasting LIPO4 on the way home. When I got home I checked the voltage on that cell and it was 0v. I moved the main + over to the next cell and added a cell at the other end. (taking the bad cell out of the loop but not removing it as it is a major pain to do) So I guess that should be #6, I've seen where other people had this problem, that's why I say to watch for it. Well good luck, you'll be an EV tech in no time!

You're not alone- Bill

I am a dealer for x-Treme Scooters. You have to buy a controller that fits the 4000li amps and volts.

However, the problem that you are describing could be that you have some dead cells in your bike. I would have your batteries charged and then put a load on them to see if they all are good. If not, then see if you are still under warranty. Battery warranty is for 1 year.

Where are you located?

Dear Jen from Green Extreme Scooters,

1 year battery warranty on a 4000li ??????

Everything I have ever read says that I have a 2 year warranty on the batteries for my 4000li. Am I missing something?

"Am I missing something?" On the contrary, you got an extra year!

You could get a kelly controller for less than that that would be regen ready and programable.

I would recommend the 72201, it's 200amps ($399), the next up is 300amp(better). The 150A $339 might be a little weak.
I could help talk you through installation and even rigging variable regen braking if you like. I'm not 100% sure on this, would help to know the specs on the original. I'm surprised they won't just exchange them. I heard the 4000s are regen capable. Anyone know about this?

This is the controller I used on my XM3500s. I also got a 0v~5v thumb throttle and mounted it upside down on the left mirror post so you can work it with your left index finger while keeping your other three fingers on the disc brake (left side) I just pull lightly on the right handle then work the thumb (finger) throttle with my index, it's awesome! My cycle analyst is showing up to 15% return from regen in neighborhood driving. About 7% average for longer trips with less braking. As I have stated many times I have had many problems with my scooter but still love it. They will get much better in the near future, the technology is all there, it just needs to become cheaper. I would keep insisting that extreme send you the proper controller. I have run my 3500 W/24 cells=48mph 28/cells=54mph. But it's pretty flat where I live, you might burn something up on a long hill, but so far I've been ok.
