Battery Pack Rebuilds

You're xootr ex3 is no longer going as fast as it used to when you barely bought it, it's lost it will to live. It's dead right, time to chuck it? Nope the most likely culprit is the battery pack, like all rechargeable batteries they have a certain Charge/ decharge cycle life, so depending on the amount of miles you put on your ex3, you'll have to replace the battery packs every so often.

The battery packs consist of 21 batteries in arranged in 3 rows of 7 , I'm not really sure the specifics of the batteries themselves, but a couple of years ago I found a company that was able to rebuild the battery packs to it's original state. I don't remember exactly what company I used, but all I had to do was ship them the battery pack, and they were able to determine what kind of batteries where in the pack, and re-used some of the proprietary parts in the pack for voltage regulation, and rebuilt the battery pack back to to it's original state. The batteries they rebuilt the pack with even had a higher capacity, hence longer range, than the original pack. This procedure cost me about $140, which was about the same price that xootr used to sell the pack for.

I found another company that I'm sure would be able to complete this task (I think that this might actually even be the same company I used before)

Unfortunately Like I said on my previous post, I'm on a really tight budget right now, so I can't get my battery pack rebuilt right now, but this is one of the things that my xootr needs in order to get back on the road again, so I'll let you guys' know as soon as I start the process.

Hi, I just ran across your site and got excited that there might still be some of these eX3s around. I have an old non-electric xootr that I've been using for the past 7+ years and recently got the idea to see if I could somehow convert it into an electric, or find an used one for sale. I've never seen an eX3 in person, so I don't have the foggiest idea how they designed it yet, what motor and batteries they used, etc. I'll be checking out the links you posted next, and will be checking back in to your blog to see what you've been up to. Thanks for creating the blog!

Hey Kyler,
You're the first person to post a comment on my blog! I hope to start the xootr ex3 project up again in '09, so I'll be posting my progress more frequently.

Every once in a while, I'll run across a xootr ex3 for sale on craigslist, or ebay, and they're usually a really good deal (less than $200).

All I could say about the Xootr Ex3 is that it's still the Mercedes of electric scooters, very well engineered, and built, (built in the U.S. not China), just like Xootr's non-electric scooters.

Hi There,

I have a Xootr EX3 electric and live in England. I have hardly used my scooter but when i did it was really amazing. The acceleration and top speed that came from it really belied it's size. Unfortuanetly my batteries died some years ago and it has been sitting up in my loft ever since. I came across the site you have mentioned (trnbatteries) but found that they will only ship items outside the USA if the order is above $250 and thats without shipping charges! So until i decide to buy maybe 2 batteries at $180 each or total my goods up to $250 then my scooter will have to sit where it is which is a shame really. Good luck with you Xootr anyway and i just thought i would like to say hi at the same time,

Cheers,

John F

I just bought a used EX3 and also feel it needs a fresh battery pack..i will check the site out, thanks!
I also think it needs new brakes..where can i order new pads for the front and what kind is on the back? and how can i determine if i need to change them altogether?

Hi There,

Just a little update on my Xootr Ex3 that's been sitting in my loft for many years. I ended up buying 2 x 3800mah 12 volt battery packs and wiring them in series so they ended up taking up both battery compartments underneath the scooter. I had to modify the charger plug on the scooter body to except a headphone jack point which by the way guarantees that you never put the plug in the wrong way round and blow the speed controller. I have had to buy another type of charger as well as the original one relys on the signal from the negative co efficient themister to regulate the charge to the battery. My original battery thermistor broke and i haven't a clue as to what exact replacement i needed because of lack of info. Anyway i will post another comment on how my scooter performs in the near future.

Estephanovich said...

Hey Best of luck with that John! It's a shame that TNR won't ship out of the US, but it looks like you're doing well on your own :) Keep us updated on your progress. Cheers!

Estephanovich said...

Also forgot to say John, feel free to send me any pictures etc. at email@oaktreeit.com and I'll go ahead and post it on the site!

Thanks

Greetings from TNRBatteries.com
If you have an EX3 scooter and need a battery we can now ship them overseas.(Some countries we are legally resticted from shipping to..15-ish)
There have always problems with shipping batteries because customs doesn't has "0" knowledge on batteries and there is a misconception by them that all batteries are going to self combust and take down a plane in transit, better to be safe than sorry I guess.
Call: 1-800-346-0601 / 407-321-3011
or
Email: jc@tnrbatteries.com
....to place your order.
Thank You,
TNRBatteries.com

I've had my EX3 for 4 or 5 years, but never had a decent battery. I just bought one from TNR, plugged it in & charged it up, and WOW. This is fantastic!

thompsonneil said...

Hi there, I'm Neil and have grown very fond of the xootr ex3, only problem is I don't have one! If there is anybody you may know of (or you yourself) that is selling their ex3, please count me in as your buyer. It would be perfect for my daily commuting needs as I really hate relying on disgusting, giant, petrol machines to get me to where I need to be. Ex3 would be just perfect for me!!

would love to hear from you, thanks! =)

Ninjajohn said...

Hi there everyone, Hope your all doing well. I have posted a couple of videos of me on my Xootr ex3 on you tube. Just type in Xootr ex3 and see it in action. Anyway it is going like a rocket and can see why there is still a following Oh by the way Neil, I have been trying to contact you via email but your mail box keeps seeing my messages as spam or something.

Phantom said...

The EX3 was my transportation of choice until the batteries died, and I ended up buying a Segway i2. I don't regret the Segway, but I go places where it can't go, or where I'm nervous about leaving it.

I'm going to get my Xootr Street scooter serviced today, but honestly, that doesn't equate to anything motorized. I arrive at my destination on a hot day, sweaty, which is what I'd like to avoid, and the reason I have a Segway and loved my EX3.

This blog has inspired me to get my Xootr EX3 batteries renewed.

James said...

I found your site as someone that is looking to find a seller. Is there anyone out there looking to pass on your EX3? I've looked at many scooters from past and present and this one seems a perfect fit.

i have a Xootr ex3 still in very good shape but with exhausted battery. Anyone interested, just email me at jhaynet2004@yahoo.com

Dan said...

Could the person who posted the Xootr for sale please email me @ danbruner5@gmail.com. I would be interested in purchasing the scooter.

Thanks Dan

Hi I am looking to purchase a ex3, please email me @ dion.wright @ gmail.com if you have one for sale and willing to ship to australia

Anyone with a speed controller for ex3 for sale or know where I can find replacement part ? Need 2-3. Heck, I'd buy 12 or more if I can stock up on spares. Email me at hooyahay@yahoo.com

thompsonneil said...

Hi all, I'm still on the hunt for an ex3 so let me know if you've got one to sell. Also, it would be interesting ro hear your opinions (current owners) about the ex3's sturdiness electrically - controller and so forth. Any reports of it blowing out? Anyway, cheers all!

I've had the xooter EX3 since 2000 or 2001. I haven't used it for the past 7 years. Now that I am working downtown and have to park a couple blocks from my job, I figured the xootr EX3 would be a great way to get to and from my car. The problem is that the battery pack needs to be replaced. Rather than go through TNRBatteries, I looked up local battery repair shops in or around my city (Sacramento). I found a place called Batteries Plus and handed them the old battery. They told me they can create a new battery pack for $120 and that it will take about a day to complete. I dropped it off this morning at 9:30 am and got a call at 2 pm stating it was done. I hope this works!

Jason Leaf said...

I would love to buy an ex3 if anyone still has one... j.r.leafATgmailDOTcom

Luke Kwan said...

alpha Qover,

did the batery work?

I did the same a few years back, and after spending the $120, it worked once and then my xootr never worked again!

I think they didn't create the new battery correctly and it messed something else up!

Anonymous said...

Luke,

Yes...the new battery still works. It has been almost 1 year and it still works.

I traveled to the company north of San Fran in wine country two years ago. They were the ones who manufactured those controller board. I met the engineer who was nice enough to explain to me the power design of the EX3. They have no more controller boards in their inventory. Said that they need a 10,000 minimum order to produce more. If I remember correctly , the company name was Transmag .

john doer said...

Oh, they told me the main reason why the board will burnout is - the regen use. So, specifically - do not use the regen switch or better yet , somehow block the thumb switch from moving forward somehow. I learned the hard way because I fried one of my controller boards that way too.

I'm selling my ex3. See my Craigslist add

Anonymous said...

I have a EX3 I might sell. Does anyone know what they are worth? Mine runs, but the batteries should probably be replaced.

alphaQover said...

On ebay, I've seen them sell for $525-$545. I sold mine for $540

Anonymous said...

Does anyone know what the "thing, thermistor" that is connected to the battery. It's looped with a blue wire thats solder to the negative pole of the battery array.

Thanks, Steve

zander said...

anyone have a manual or instructions on removing the rear wheel? I need ot replace mine (and i have the replacement) but I cant figure out how to remove the drive wheel...

Estephanovich said...

Zander,

Where did you get the replacement wheel? Did you figure out how to replace the wheel?

I would love to write up some documentation on how to replace the rear wheel.

I recently decided to start using my ex3 again, but there are a number of things I need to fix on it before it's road worthy again.

Michael Smith said...

I highly recommend. They have the largest selection of Bromptons I've seen anywhere - more than the two bike shops I checked out in London even. electric bikes nz

Hey all. I just got off the phone with TNR Batteries and ordered a fresh battery for my EX3... It's not on the website any longer, so you need to call them.

I corresponded with someone named Robert via their online request for help. Very prompt, should receive tomorrow. No news will be good news. Excited to fire this monster up again.

David Luftig said...

Love my ex3. Glad to know where new batteries can b bought. I would contribute to a kickstarter campaign to reverse/ re- engineer this amazing scooter. (Is it's patent expired? )
The "Maker" (Make magazine) community has talented people to make this possible. PS Bose invented a sonically controlled shock absorber. Perfect for solid wheels( dream accessory)

have a xootr EX3 that i will be selling. It is in really good condition. I have replaced the front handle bar / down tube assembly and made some really useful mods like adding a re-closable plug to the throttle wire so it can be disconnected easily if you need to work on the front handlebar. I also added a thick pad to the rear of the deck to absorb road shock on the riders back leg. This is the dual battery pack model so you can actually get 20 miles to a charge with it. I'll be listing it on eBay if anyone is interested. eBay Seller Name: applegenius

Jon Froderberg said...

You can also purchase batteries from batteryspace.com with this part number: PR-CU-R381
I purchased my new battery on 8/8/2014 for $124 plus shipping.
They did an excellent job of building and testing the battery and were very helpful in answering my questions.

john doer said...

My EX3 was sitting around for over 8yrs, I charged it overnite n it still runs ! Very slow but does work . I plan to convert to Li-ion packs finally . Will post update when done .

I've got two of these Ex3s and debating whether to put them on ebay. You just can't find quality products like this anymore. Anyone know what they are worth now?

How much are you asking?

The_Prods said...

Hi John, i'd be interested in purchasing one or both. Contact me at the_prods@yahoo.com

Ninjajohn said...

My xootr ex3 must have only covered approx 8 km of actual use before my controller board wentpop. Has anyone out there converted theirs to use another controller board which can be bought off the shelves?? It's a real shame about it uses bespoke controller boards. I wonder if transmag would sell the design schematic of the board to help repair their fragile boards they produced for the ex3....

XootrEX3 said...

Anyone interested in buying parts like the controller, throttle, charger, etc? I have an old ex3 that's been sitting in a closet for close to 10 years. I bumped it into a high curb and the front end got bent. Otherwise, the electronics are still good except for the batteries which are probably too old to hold a charge.

XootrEX3 said...

Here are some photos and a video with the throttle/regen. The battery only lasts about a minute after charging, otherwise the electronics are working normally.

Can someone post a picture of the installed battery pack and bits underneath? I was given an ex3 but seem To be missing part of the wearing harness, As there is no where for the batteries to plug into the machine. Thanks.
