- In this video, I will show you how to repair a Swagtron Swagger 5 battery pack. All electric scooters of this size virtually have the exact same size battery pack: Xiaomi M365, Lime, Bird. The Swagger 5 is especially similar (if not the exact same) with the Xaiomi M365. This battery issue is an extremely common problem with all electric scooters. I will also show you some tips to solder 18650 cells with a nickel strip. The same process can be done on an electric bike battery.

Thank you for posting this video! My son's had the same issue and I was able to repair myself thanks to you. Couldn't find any repair shops willing to touch lithium batteries. You made my son happy... thank you!
I had my scooter about a month before the battery shorted out.. It's been under my bed for a year. After watching this video, I'm totally going to pull iit out right now. good luck and be safe everybody!
thank you for this video. very helpful. do you have a video of replacing the controller or overriding the speed limits of this model?
Great Video, sir!!
You really know your stuff.
I've been using mine for two weeks now, and your point about the board leads me to seriously consider opening up the bottom and putting cable ties as yours has it to at least slow down, if not prevent, the nickel strip separation that you had to repair with yours.
It's an otherwise excellent scooter, and I intend to use it for several years.
Would like to see a controller upgrade for the swagger. Agreed that it is small and could use an upgrade. I would appreciate a video and/or link to one that you would suggest. Great video, nice work.
I'm interested in a breakdown and upgrade for the swagger 8. Can you do that?

Nice repair sir. Should hold up well with the double layers and those relief corner bends.
I have a spot welder for making large packs, but on smaller tool,/appliance/mobility packs I still find it easier and faster to solder. A few tricks I have to minimize cell heating and contact resistance:
-scuff the contact surfaces with fiberglass scratch pen or fine sandpaper; lightly pre-tin the mating surfaces
-slightly chill the cells short time in the fridge or with a puff of freeze spray on the joint just prior to soldering (I use inverted canned air, but be very careful of frostbite!)
-hottest iron setting, clean tinned tip, leaded solder, extra flux - all to maximize wetting and minimize soldering contact time to a few seconds. A powerful iron also helps to avoid premature cooling/ pooling - (the finished joint should be smooth surface and not resemble an arc weld.)
-hold the tab down with a sharp pointed non-metallic stick (eg a kebob skewer or toothpick) to maximize direct tab to tab contact in the joint
-as soon as solder turns solid remove the stick and dip a cotton swab /q-tip in a small bowl of alcohol and immed place on the joint to suck the heat out, then use it to clean off the flux
Thanks for the vid. That scooter runs nicely!
As usual great content!! I thought for sure u were going to put two Kobalt batteries on it. Maybe when the other batteries die
I thought about it. A Kobalt 40V battery would do just fine. Problem is how to put it in the scooter because it does not fit.
vuaeco U could make a vest or back pack for u and your son. Perhaps a bullet proof vest like the cops wear. And a couple of xt 90 connectors. Whatever voltage u feel like. If your in a hurry to work, use the 90 volt connector. Safety and eco friendly.
I went through 5 swagger 5s and I FINALLY know why they keep breaking down. Thanks!
Why bro mine just did and is there any way u can help fam 🙏🏽
You guys ever figure out if this works??? I wasn’t sure you can replace a battery for this scooter.
@@georgelopez4663 you can replace the battery on any scooter. It's just about replacing the cells. you can even add a second, parallel battery. watch some tutorials. The BMS looks dumb on this scooter, i would replace it with something safer and less likely to break. There are a lot of good cells in even a bad battery that can be salvaged. you can even revive dead cells by jumping them with the same voltage they are rated for.
Nice wrapping of the battery....can u do my christmas presents?😆
Hey jr eco is not so jr anymore since the last time he tested for you, does he take as much interest in your eco passion, or couldnt careless 😁
LOL. Jr. is getting bigger than me now. He eats too much hamburgers. He is only interested in riding these toys and not so interested in fixing them. :D
I seriously went "Woooowwwww" when he retested the voltage after the repair. I'm so impressed. I've been so frustrated with SwagTron and their repair policies/procedures. I would GLADLY pay someone to repair my Swagger 5 locally. I don't suppose you live in Los Angeles??
Hi . I Have taken on a project scooter that is not working and looks like your battery pack here. Are you aware if there is a ''Z'' fuse as shown on some other YT videos . I am having a troubling message/problem there is no communication with the battery (ERROR 21). How does the BMS talk to the mother board ?? Is the Bluetooth emitted from the battery BMS board ?
Hope you might be able to help me a little here . Best regards Don
Question what if I am not getting power to my red and black wires at the plug but I'm getting full Voltage at the battery pack?
Do you know where to buy a replacement battery and charging port?
Look I have a Q30 I'm trying to take the stand deck off so I can change the motor and I got the screws off but I still can't take it off any one have ideas
Buen Dia. Tengo una pregunta. Mi swagger 5 lo cargo hasta que marca batería completa. Lo uso y al corto tiempo digamos 4 mins de uso se apaga. Será la batería o la rueda?
Hola ya lo pudiste reparar?
Helpful repair video, thanks. Although I wouldn't recommend wrapping up the entire battery pack with foam sheeting is necessary as it will act as a thermal blanket and retain heat which may shorten the lifespan of the cells especially within hot or warm climates. 3" x 1" x .5mm foam strips shall suffice in providing generously adequate shock protection.
Just folded my e5 to test for correct voltage. I’m getting 37.4 volts on the battery side but my controller side is showing same. The switch is off. Why is the controller side showing voltage? It’s alive and I’m afraid it will short out due to the male contacts.
Too long heating time while soldering. This is very dangerous for batteries.
Hi my scooter is always is at 100% and turning off random times xould u tell me how to fix
Great video thank you for your help
The whole apartment burns down because of such repairs. sad.
Everyone wants to no where to buy a replacement battery.
Nice work, just need some pretty shrink wrap. Like the back pack idea for higher voltages with kobalt battery's to test. Keep it up.
The thicker foam actually provides more protection from the shrink wrap in this case. It acts like a shock absorber.
The swagtron swagger 5 boost version is better.
Very nice video, thanks for your time
Good job but ..how the those cells vent if covered with foam?
Hi guys, hope you all well. Does anyone know how to change existing connector on battery to right one. (ordered new battery but wrong interface connector came) thanks a lot
That looks pretty cool 😃👍 love the battery pack. 😋
Where can I buy a bms new dash board and bms?
Hey there! Was wondering if you could help. My individual cells are 3.51 and not 4 does that mean they’re bad? I’ve soldered them back to the board connections but when I test the positive and negative it still shows 0v. Could it just be that the board is bad or a combination of things?
Im Sean from New Bedford , I have 2 swagger 5's and they are slow about 14mph and im only 160lbs...... How fast is yours and what can i do to make it go fast as possible my Cambodian Brother...
I'm considering upgrading the battery on my hiboy s2 pro. But I saw a video on the ninebot where the battery was upgraded with a higher amperage battery but the phone app does not recognize the new size of the battery. Does the xaiomi scooter exhibit the same battery display like the ninebot?
Also the generic batteries require data hook up up to connect to the scooter that have this cable.
As a curious note, since the ninebot sees the old battery size. What happens with the scooter when the phone app see 0% when there is actually say 20% as an example.
Good video. Just one thing, you're applying to much heat to the battery. I know there is a nickel strip between the cell and the soldering iron. Nickel is a good conductor of heat. I repaired my broken battery terminals with tinned copper braid. It has been working for 2 years. Then the BMS failed a year ago. It would not charge the battery at all, but still powered the motor. I replaced the BMS with a generic 10s one and so far so good. I also added an external 10s4p pack to more than double the range. I charge them separately. It works well because I don't connect packs of different voltage together. BTW the front tire on mine was shit from day 1. It constantly leaked. I replaced it with an airless tire like the rear and have had no other trouble
Thank you. This is the first time I have seen the batteries insulated using foam and tape instead of heat shrink. I have a Swagtron e-bike and my batteries no longer charge to the full 42 volts. I'm going to inspect them.
The rear wheel of my scooter does not move even a little bit. When I bought it it worked perfectly, we used it twice and it was two months without using it and suddenly when we wanted to use it it turns on but it doesn't move.
I find when working with Li-Ion most of our safety and quality protocols call for any tab that directly touches a cell to be Spot welded. Hot soldering iron has the possibility (limited of course) to ignite the li-ion cell. You never know when there might be internal unseen damage with a cell that will cause it to react to a hot soldering iron.
That's why Li-Ion will soon go the way of HD DVD's when up against Blu-Ray with the Blu-Ray equivalent being Lifepo4 since they're superior in every way BUT don't explode into flames just because you looked at them funny the way Li-Ion most assuredly do.
I’ve actually had a lithium ion 18650 cell explode right in my face before but luckily I always wear safety equipment when soldering any battery. I’ve been doing this for years and only had it happen one time and it had to be from something that was internally wrong with the battery like you suggested in your comment. The reason I say it must’ve been something internal is because I had already completely finished soldering the battery and it was just setting on the bench for about 2 minutes and I happen to notice the wrap started to peel away from the battery so not think I lean over it to look what’s going on and then boom 💥. I inspected my solder points after this happened and there was nothing out of the ordinary of every other one I had ever done. I just thought I’d share this because like you said the chances are there of the battery exploding especially if you don’t know what you’re doing.
I have a question, about the control module.
I have this model scooter, and it rides then turns off, it charges sometimes, and I notice if I tap around the control module it’ll turn on but only for a split second. Help! How can I work with you
Should alternated the zip ties to help keep the battery ends from touching the chassis
Good job sir
hello i fixed the battery the way you told us test terminal to terminal is over 40 volts but testing red and black wire like you said i have no voltage can you help me and tell me why?
Can u please help me bro mine says e5 I'll be riding it and it'll just cut off after a certain amount of time
How can I fix or replace the light?
And how to tight the handle base to the support pole?
Can you tell me which one better( G1 and G2 Nissan Leaf Battery) thank you so much.
did you do a video on fixing the power button i can't find it and i need to fix mine ???
Damn, you are amazing!
Excelent!
That's some serious point of failure you spotted there, Nice. Where would one find the restrictor wire on a pure air e scooter XD or is it software-based?
Where would I splice in an auxiliary battery for my e5? Battery side or controller side?
You do excellent work, I was hoping you might be able to do a Hiboy Max electric scooter mod!!!
im having problems with my scooter can u help me
Where can I buy that circuit board soldered to the battery ???
We’re do you get a replacement battery
Wow. Awful craftsman
Only 1 recommendation: use AT LEAST a 60W soldering iron (i suggest a cheap blue one with a simple temp. control system (a variable resistor)).(the problem of those soldering points is the temperature, since it's too cold the tin wont stick well (like the previous soldering), while, at around 325-375 c° the tin will melt instantly.
Mine is a Weller 50W and it works just fine for this purpose.
@@vuaeco yeah it was just a suggestion, cause that first spot triggered me a bit, lel sorry
What temperature did you have the solder at?
Where do you get it from
⭐⭐🌟⭐⭐
Hi do you know if a genuine xiaomi m365 battery will work in one of these scooters thanks
Yes, it will.
@@vuaeco without plugging in the data cable from the battery I got one of these scooters with original xiaomi m365 battery but I don't wana reck the battery and wasn't sure if the battery works without the data cable being plugged in thanks
Without data plug from battery being plugged into esc thanks
Yo bro I need your help mine died and the charger works but it won’t charge no more do ik a new battery ?
Watch the video again!
All I did was bro was take off the bottom part were all the screws were put it back on and it worked suprise to me I thot it was over but ion even kho I didn’t even do nothing but remove the bottom part
FlochAt you Khow about e scooters bro ?
first
I have 2 of the same schooters where can I find something like a replacement battery for these scooters
Wht did u do bro
@@youngdollo2430 for the scooter?
Oscar Rmz yea bro mine the charger won’t charge on the scooter but the charger works on a hover board I got so I’m pretty sure it’s the scooter but ion kho Wht to do
@@youngdollo2430 what I did was just open it up to check the wires its really simple not too complicated
Oscar Rmz fasho fasho fam then Wht when I open it
