- On todays video I show what I have been doing with the lithium ion cells from the uno golf cart battery.

good use of the batteries. "More power" Tim Allens voice
Love it.. got a spot welder also and playing with batterys .. its Always good to know how to build our own battery.. great video!!!
Great video. Always good to learn something new.
Great idea!
Ryan, if you want to know more about Uno, and their batteries, or the owner, reach out. That blue "hot wheels" golf cart they featured in all of their promos is mine, I loaned it to them to figure out why their batteries kept failing, and they broke the contract in the end. I have 3 failed Uno units, and probably have more experience dealing with Trent and Nick than anyone.
I have 1 taken apart on my bench as well. Great videos on the teardown. I did one too, but never got around to edits/posting. Glad to see someone making use of all the cells.
The cells have been great. I think since the bms was placed in all that foam, that was the problem for them. If they would've designed it a little better with a serviceable bms then it would've been a good battery. I talked with both trent and nick for a while but then they told me the batteries were being shut down and I haven't spoken to neither since. What are you doing with your battery cells?
@@Fentertainment I want to find a BMS that will work and try to save the packs. I bought 2 to run in tandem/paralell, and redesigned my battery tray around doing just that, so they sat farther back closer to the motor. Left me tons of storage room in the cart. Id really like to make use of them. I can do what you are doing, but with 2 packs worth, It'll take me 300 years to use all those cells. LOL . I have 2 confirmed failures, and this 3rd pack I limped along seems to be on its way out. Sitting idle, not hooked to charger or the cart, it has been over 110 degrees on the BMS side of the case for over 50 hours. Battery state of charge is slowly dropping, and its staying consistently heated and hot to the touch even though outside air temp is 60-70'ish degrees where it is stored. I suspect that one now has a full on short in the BMS that is working its way into full out failure. Does not stay charged for more than a week or so, and battery life is severely diminished. Ill take that one apart here soon as well.
My first pack blew a hole out the side of it about an hour into its first use. I was one of the earlier adopters, and a vendor. (I have a video of that posted) That's when Nick and Trent got on the phone with me and they couldn't figure out why it was happening, said they had other failures. I offered up my cart, it got shipped from WA to their facility in Idaho, and they did all the testing, etc, redesigned the BMS, did those videos you clipped in that have my cart in them that they have since taken down. (they were served a cease and desist to stop using my cart in promotional videos, since they violated the terms of our contract, they ignored that until going belly up). We used to talk regularly, all kinds of engineering info, and Id have my input being pretty savvy (ASE Master Tech). They claimed to have it all fixed, but then "forgot" to give my cart back. (were supposed to have it for 30 days, with extensions available if I agreed. After they fixed the battery, I got ghosted for a few months until they finally sent my cart back) Finally months later I got it back, with one DOA battery and 1 working. Cart was severely damaged, actually had to go get it back myself from a tow yard, as it never got delivered to me, and went "missing" with no one telling me where it was, its just a whole mess, insurance companies involved, etc, and they left me high and dry. Trent promised via text to get it all taken care of and pay the damages, and never did... We had a written contract and they claimed in writing to take care of any/all damages prior to me loaning the cart. They never did, blocked my phone number even on the main company line, etc. They threatened all the FB groups and forums into removing any posts or comments I made and did everything they could to silence me to keep the real story from getting out about what they did. (I have all the messages from those moderators and owners of those groups with some pretty wild info). I have all the emails, texts, etc. I'm an open book for anyone that wants to see just how big of scumbags those guys are. Honestly, I couldn't be happier they are out of business, and not screwing more people over. Too many people already are worse off after spending all that money for their crap product. Titan battery needs to go too. Hiding behind Titian, after leveraging it to build Uno, just to leave everyone with the useless "10 year made in USA warranty" is just shady.
I never had to help them, and got royally screwed by them for doing it. Nick has threatened via text that he is a marine and is going to come kick my ass, etc. just a few months ago, after they were already belly up. Some real pieces of work those guys are.
I would collaborate and send my footage over, etc, if interested in releasing the UNO story. Its a doozy, those guys are flat out fraudsters and liars. I've kept every record.
Great reuse of the batteries Boss!
3 of us here where I live have UNo batteries. All three had to be replaced by UNO before they went belly up. I put mine in a DS that I flipped and bought a new 105 ah Varner that I love. My friends are still running their replacement UNO’s. One of the boys still has his original in the garage because they never sent him the return postage. I don’t have the skills or nerve to open it up and take it apart but I’m going to see what he wants to do with it and get back to you. By the way I thought it was a great and interesting video and enjoyed it.
I was scared to open mine, But now seeing how it came apart I believe you could do it. Right at 400 cells in that battery, Dont let them go to waste! I cant believe they didnt make him send it back. I get giddy with stuff like that. Been trying to lithium swap everything round here. Trying to find old tools that batteries quit in so I can bring them back to life. I can always use more tools.
You could probably build a small 12v/30ah battery for golf cart accessories (or anything else thats 12v).
Wondering if my 1 cell is under charged also.Some day I’ll get to it.
Good for you Ryan for making use out of that Uno kit. It’s still so depressing I have a $2000+ future battery farm in my golf cart.
Do you mind me asking if your precedent was an Excel or IQ you installed your Teekon kit on? I’m in the process of installing mine on a PH excel harness and not having luck.
I had it on my 14 for a while which was an excel with eric charger. Its on my wifes cart now which idk the year due to missing numbers on panels when I bought it as a parts rig. But its an earlier model that had the 1510, I think thats the iq. tbh im not exactly sure.
I need one like that for my boys power wheel. you ever want to sell one I'm local.
Handy! Dumb question, why are you stripping and rewrapping?
Not a dumb question but when I break away a cell from the pack it usually rips the original wrap. So in order to protect each cell Im wrapping them. When installing the cell into the new holder the ripped cell wrap will get caught on the plastic. Plus its just cheap insurance.
Uno sucks. Bought two and they went out of business with zero warning. So much for my warranty.
I'm 3 for 3 on failed units, and they used my cart for the R&D, and still screwed me over...
