This video really helps a lot. My scoot recently stop working and I brought it to the service center. The service center informed me that my scooter's warranty is voided due to liquid damage and was charging me for control board and battery replacement costing at around 250usd which is too expensive. After watching this I tried to diagnose the parts by myself and It was just only a bms error. I just reset the bms and it works. Thank you for sharing your knowledge
You should name the specific service center and its location so they can have pride in the fact they are ripping people off. (Assuming you thoroughly tested the scooter and this was the only issue).
@@kevinsellsit5584 I bought my scoot at technigent in Makati. Hinatid ko sa technigent mismo ung scoot na pinick up Ng "service center" which is grimalkin corp. Located along Quezon city. I still have our conversation (with the Xiaomi representative) via Viber 😉

@@amazingmotivation1344 same prob din po sakin, bought it from shopee and I contacted the seller, sabi po nila i ship to manila at ipa service center nila (cebu po ako). Nagbayad lang po ako ng 800 for battery reactivation fee. Akin na din po yung SF. Skl keke

Perfect video left nothing out. Extremely detailed and thorough explanation
This was the most informative video that I've found on the matter, thanks!
He makes it look so easy haha.
He has so much knowledge and soldering skills and spotweldding and more needed equipment.
Thanks for an excellent video, with good camera work and narration. I have to check out your channel.
you, my friend, are the man !
Best video so far from someone who understands battery technology
Great video. Wish I had your knowledge of BMS and 18650's. I fool around with small lighting projects, but maybe one day I will take the leap and try something like this repair.
Hi, thanks for the excellent video. Quick questions, what is your spot welder? Full details would be greatly appreciated.
Great Video and Good explication about troubleshooting a faulty battery . You can get the rest off the cells unbalanced gest beacouse it’s impossible to perfectly match used cells with new cells . But you can grab out a good cell and make a discharge test and see how many mAh you can get and after that you can put new ones or used ones as close in capacity possible .
Great work, really appreciate your efforts !
A very well made diagnostic video. Not many will put the time and effort into one. Thanks
If you really want to fix anything you really need to spend time money and effort. Otherwise...forget it. When it comes to get anything repaired nothing is easy.
Great video. Thank you for the information. It was most helpful.
This is one of the best quality videos i've come across on this matter, thank you very much for the detailed explanations !
Very high quality video. I really appreciate you speaking in English!
Yeah, he might have an accent but he's very easy to understand. :D
Matias Langaard You’re kidding he’s rubbish at English
@@kentcyclist What part of the video did you have trouble understanding?
Cult Watch then your literally deaf

Awesome diagnosing work! 👏
Good job on the spot welding, I was wondering if you would do that! It's difficult for me to suggest to anyone to attempt to solder these batteries. Too much heat is required and the solder is quite prone to mechanical failure. Really pro video. What would the final repair bill for a customer bringing this scooter in the shop??
He bought it.
Very well made video. In-depth. Highly informative. Thank you for this well thought video
Amazing tutorial. Thank you!
Very useful information. Great thanks
Thanks, you helped me with that bsm modul reset button! Baterry showed on output 16v, but on the cells (before the bsm modul) showed 33v (discharged). I reseted the bsm modul and now flashing blue light and showin 33v on output. Many thanks
Thank-you this video helpful, how to add on external battery without error code.
Thank you for this great video. Where can I find a spot welder like yours?
Amazing work bro.
good video about the m365 scooter, thank you
Well done 👏
Covered every aspect i need

Great video my friend!
I watched the full videos it’s good sir nice tips now I have the idea to fixed may scooter too
Thank you for enlightning video - keep up good work!
Great video!!Can I find out more about replacing the rear cable?Does it need to be soldered? Or can you just change it?
most likely soldered
Bravo. Buna treaba!
Great video, no useless small talk.
Yes it was helpful thx 😎👍
Wow thank you for sharing guy
This tutorial is very accurate 🥰 my battery same there is 3 dead , it needs to replace new battery ❤️ thanks for the video
I love your work ... take a bow
Amazing video. You are a Pro for sure.
Thank you from bottom of my hart it realy helped
Simply you are a genius
Brilliant video.
Thanks for the video. Very helpful and well explained. Subscribbed 🤗
Nice, please make the video for external battery mod!
Thank you a lot!
wow! thank you so amazing
Hello my friend, you seemed very experienced so I would like to ask you if its possible to brake the batteries to individual cells without cutting every cell out of the plastic. I understand i will have to rip of the spot welds but looking at the plastic shell i believe there must be some mechanism to held in place the cage on each side? Would you know how to? What else would you suggest while doing so? Thanks in advance
Sorry if wasn't listing, but we're the LG cells the same capacity, great video aswell, very inspiring to people to fix there own packs!
ADSlammer they certainly should be
Nice Job!!!
Shit, that looked easy, but I know is FAR FROM EASY IN 'REAL LIFE' 😂 you are a genius!
It's honestly not that hard you just have to be educated on lithium batteries
Not easy very hard for me better the bring service
Last time I got out of my depth was with a pioneer DJ nexus 2000.. If you are unsure bite the bullet and pay for a proper service by a qualified engineer..... better then being left with a 13 kg paperweight.. 🤬😱😱😱
Its very easy. You just have to use your brain. And smoke a bob Marley
Pretty nice work, dude! 😊
Excellent. Thank you very much.
You are a very smart Guy... 10/10
Hi Sir, I am very impressed by your video. My starter does not work. My battery is full but it doesn’t start. Any recommendations are appreciated
Hi .. with my happened the same !! And the wheel it's not spinning well !!!
Hi! Could you recommend a video on replacing the m365 side lines. I hit a nail and one got mangled.
عمل رائع وجميل انته عبقري 😍👍
Good afternoon, I have a question for you and I think you are the best one to ask. I don't have the battery pack myself so I can't inspect it. Could you please tell me what would be the best way to dismantle the whole package and I mean the plastic holder so it all goes apart. Apart of removing the nickel tabs what's woul be next step? How does it hold together? Thank you for your answer ahead.
amazing dude 👌
Very helpful👍
really good men.
Awesome work
Good video, thanks! One question: can I use the charging port to OUTPUT voltage from the battery? I want to use my scooter as a powerbank, outputting voltage to a buck converter.
Wow, super many thanks. Mine I not charging properly. I think I need to check the cells
Excellent 👍👍👍👍👍👍👍👍👍
Depending on how long the "bad" cells were totally discharged for it might be possible to recover them. I have had luck with using a lab bench power supply to bring them slowly up to around 2.9v and then using an intelligent charger set to 100mA to go to their storage charge voltage. By this point I'd strongly recommend if the cells do take charge at this point that you then sit them for a couple days and regularly test the cell voltage to ensure they are not internally shorted before then fully charging them at their rated charging current. These cells of course may not be quite as reliable as new cells due to the over-discharge but again, I have had super good luck recovering flat 18650 cells this way.
I have tried this but is seems that my imax charger refuses to start charging since it detects too low voltage... :(
@@PumpkinOnWheels yeah, you have to revive the battery with another battery or a DC power supply with set voltage of the battery. There are tutorials online on how to do it. th-cam.com/video/EuutXrOgFroh/w-d-xo.htmlttps://th-cam.com/video/EuutXrOgFro/w-d-xo.html here is one, but there are many more.
Ehsh
Ehf@^@,$^$ ĺs,este de, r
@@PumpkinOnWheels that's exactly why you gotta use a bench PSU with limitations on current and voltage. Dead cells should be charged veeeeery slowly up to 3v.
Good job 👍🏽
good video, thanks
Hi, if I need to replace 12 cells, do I need to disconnect the BMS? or I can just remove the faulty cells, replace with the new once, and charge them to balanced 4,2v?
Thanks, great vid btw!
disconnect first.
Cool. What are the cell types in this? Apologies if its covered in the video I must have missed. Are they good cells?
Great tutorial, expert touch
Best vid ever
Use side/edge clippers to remove the plastic tabs much more control and safer.
Good Job bro
Nice video, very very useful indeed but.... Question: where did you buy your spot welder from? What make and model number is? and how much it cost please ? Tnx.
great video thank you. Where can I find those nickle strips ?
brico or gamma!
well done 👏
thanks you for this vidwo
awesome video
Thank you 🙏 man... I thought my controller was bad and I ordered another one only to discover your video
Nice work
thanks for the video
which kind of spot welder machine are you using ? it seems very efficient....
sorry i didn't read all your complete description..... thanks..
Renaud Bay I use the same spot welder and it works great! I highly recommend it!
You make an amazingly good video. Thank you. Hope to see more. 1 tip: your english is exceptional, but your accent is thick, maybe just slow down the speaking a little. I have a very similare issue with my ewheels scooter. When I get to trouble shooting it would it be possible to get some feed bcack from you directly?
Hey, nice video. How long does this scooter takes to break like this? Or did you buy broken one?
It literally says in the video if you open your fucking ears
@@callumrose5991 Yeah ture I miss that part
You make it lok so easy......🤨
I wish someone with your knowledge would do a video about overclocking m365 ant it's effect on the battery
Just drains battery faster. The main problem with overclocking the power would be burning mosfets on the circuit board and the bridge.

Hi
Thanks for educating us. I have a scooter that looses charge quickly when climbing up the slopes. How to troubleshoot the problem?
Just bought a solder gun this morning to fix a few lose solder joints on my battery, I sure hope it's just the top solder joints so I don't have to take it too far apart.
Wonderful
This makes me wanna find a broken one and fix it!!
Nice video
Ok I have that flashing / blinking blue light but also a red led on in the plastic board next to it too??
thank you rely help my scooter thank you
Your video just helped me not have to spend 200 plus dollars on new battery
Super video :-) Great work .
Thanks
@Well done Tips , I like the video, thank you for the value : )
I will glad to get advice from you .
I'm going to take flights with my Scooter often . I'm planning to separate the battery from the scooter and carry it on with me in a bag , and the E scooter I'm planning to check it .
Did you take a flight successfully with Xiaomi M365 ?
How was it ? did It go smooth ?
If not yet , Did people you know that made it successfully ?
From experience please
The known TSA Statements are that :
2 Lithium batteries are permitted.
Lithium batteries from 0 -100 watt-hours are allowed.
from 100 - 160 wh may be allowed with airline approval, only in carry-on bags .
and from 160 + wh batteries are not allowed at all.
I read new TSA information that :
" One spare Lithium battery, not exceeding 300 watt hours, or two spare batteries, not exceeding 160 watt hours each, are permitted in carry-on bags. "
:) If that's true, the problem is solved as the Xiaomi is 280 wh !! : )
So I'm asking what is the best way to flight with the Xiaomi M365 ? just simply separate the battery ? to divide the battery to 2 so that every battery will be 140 wh and get the airline approval ?
Thank you very much for your Reference brother !
Wish you the best
Nice video. Please, I live in a city where there are limited number of people who render this service (electric scooter repair.). I would love to learn how to repair. I already have an idea on how to change tyres. what are the tools i need to get. like a complete kit.
please, a guide and suggestions would be highly appreciated. thank you.
Hi, good job. I am looking for instructions how to replace the throttle, can sbd help me? thanks
Thank you :-).
You shouldn't wear a ring when playing with battery packs!
Great video , could you tell me model of charger for this scooter , I purchased one recently cheap with no charger thank you
This would be so nice,if this was realistic to do for me or any mechanic in my area.
