In this video I’ll show you - how to diagnose and repair Xiaomi M365 electric scooter faulty battery.
Found bad BMS - replaced with new one.
Found 9 dead LG LGGBM261865 cells - replaced with Panasonic NCR18650PF
For this repair I used equipment and products:
Xiaomi M365 BMS - shorturl.at/awCF0
Panasonic NCR18650PF 18650 cells - goo.gl/S75c3s
Imax B6 AC v2 charger - shorturl.at/cQWX9

Perfect video left nothing out. Extremely detailed and thorough explanation

@amazingmotivation1344 3 года назад

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 2 года назад

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).

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 .

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??

@DigBipper188 4 года назад

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 2 года назад

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

@xiaobai7060 2 года назад

@@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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EuutXrOgFroh.htmlttps://ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EuutXrOgFro.html here is one, but there are many more.

@@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.

@themaximussx875 5 лет назад

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

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.
