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

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).

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 .

@DigBipper188 4 жыл бұрын

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 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

I am just wondering, arent LGGBM261865 rated for 2600 (when I do the math of the battery pack 7800, there are 3 parallel packs so the battery should be rated for 2600) or it is not a problem if you stick 3x 3300mAh into the pack. If I get it correctly it doesnt have ballancer for every cell so is not the 3300 mAh battery „charging“ the others in pack?

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.

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.
