Xiaomi M365 Battery Issues - Diagnose And Repair

[@amazingmotivation1344]

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

[@kevinsellsit5584]

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).

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.

[@ciprianbeniuga5042]

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 .

[@Hermzkiii]

This tutorial is very accurate 🥰 my battery same there is 3 dead , it needs to replace new battery ❤️ thanks for the video

[@adamlonvideos4078]

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

[@svensporleder810]

Danke für die sehr gute Hilfe bei meiner Roller-Reparatur 💪👍

[@DigBipper188]

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.

[@PumpkinOnWheels]

I have tried this but is seems that my imax charger refuses to start charging since it detects too low voltage... :(

[@xiaobai7060]

@@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. kzbin.info/www/bejne/e6bYpYuohMx5qNGcttps://kzbin.info/www/bejne/e6bYpYuohMx5qNE here is one, but there are many more.

[@umloginqualquer]

@@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.

[@metatechnologist]

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??

[@george-broughton]

it would be neat if you could just 3D print a casing for the battery such that you didn't need to spot weld the cells themselves, and have all of them on springs. I know things out there exist but from what i've seen they're impractical for retrofitting at best.

Great repair video but a bit overkill, you might as well just get a new battery than mess around with a new BMS, replaced cells, external chargers, if doing 1-2 repairs its not even worth all the tools, just buy a new scooter lol. For battery issues I usually replace the entire battery pack before replacing part by part.

[@Lev_Shor]

@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

Is there a sealing on a battery compartment cover? I'm driving it under rain, wondering if I should do additional sealing ouside..

It's sealed in plastic so will be fine in puddles , but don't submerge it obviously, if you're worried go check the screws to make sure they're all still tight👍🏽

[@faktytv9499]

Good Job bro

[@paguliukas]

Best vid ever

[@TeamAmierliaTV]

Doesn't the bms 7:08 balance all the cells? So why charge them individually? 😅 Nice video anyways so informative. I just need guidance because I'm doing the exact same thing, but I don't have the charger

[@dummydummy1421]

Remove the bms because it often kills the expensive batteries. Use Tesla 10 amps fuse design for security (🔥) on cells and cells logger/ checker to control the charge and discharge limit ( bip alarm). Your battery will last longer... And this the more expensive part.

[@Mprikiman]

Elaborate please. I know about the Tesla fuse wire config but not the rest. How we should build the battery pack?

[@damiencrean904]

Ya, this kinds of issue mostly found in electric scooter or bike, due to battery bms also gets spoil.

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.
