XIAOMI PRO2 Battery - Repair 1 [Teardown & Cell Swap] 

aye - I'm glad someone enjoyed my transitions ❤️ hope you're well man 🤘🤘

Don't suppose you have a link to the spot welder and lipo battery charger/discharger/tester I see you using in your videos?

I even made a video on it 🤘 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_dL8hCMCnlY.html

just don't wash it man ..

glad people are enjoying them 🤘 thanks for the kind words

the battery just passes that wire right through maybe you have some corrosion on the BMS connector (the one that plugs into the ESC)

all the ones I've seen are packed with LG MH1 cells

@@Darieee thanks alot, do you think if i add a second original battery via Y cable will work out (the bmses wont do conflicts each other because both will be original) ? Just for more distance.Now i have custom 2nd battery 36v 12800mah added but i want to to change it with original pro 2 battery because i find em cheap.

check the g30max LD battery too - you'll love it 🔥 m365 tools is the name of the app - unfortunately it's android only

veeeery tough .. I managed to score an original 0 cycle one off my local ebay type website .. I still can't imagine how that battery came to exist .. but it's in my scooter and is working fine .. basically a newer used one would be your best bet - or contact your local xiaomi service to see if they'll sell you one

@@Darieee they dont i called the headquarters in my country. it comes down to just throw it away. i hate that spirit

@@klaasj7808 yeah .. that really sucks .. what country is it btw ? maybe you can coax the service people into selling you one ..

you can, but you'd have to find a way to hold it in snugly ✌️

I'm not sure it fits even with that metal casing off though ..

I think those are torx T8

@@Darieee thank you🙏

@@Darieee these are torx T10 eventually as I moved the undercover of the scooter 😉 before taking apart the battery inside for balancing the cells do you believe I might try to charge the battery just bypassing the BMS cable to the controller? Since I have an unbalanced cell pack (about 3,750v when fully charged) is it going to charge any further bypassing the BMS I wonder? Or other cell packs will charge upwards as well and that will press the battery in total?

@@vcdroneGR all the BMS work is done inside the battery - and no ballancing will occur without the BMS inside the battery ... unfortunately you'll have to open'er up and work on a per-bank basis to asses the situation do keep us updated with what you find in there though 😀, sounds interesting !

@@Darieee OK I understand what you say. Since the BMS is inside the battery and connected with cells (the blue light is blinking even I disconnect the bms cable from controller) maybe if I disconnect the BMS ribbon cable from the banks inside the battery and then give a try to charge without BMS 🤔 but I don't know if the battery is charging then if it is designed to work only with BMS on it. Otherwise I will charge single cells separately with my imax hobby charger at 1s 4.2v max to align them with current voltage 😎

how ??

@@Darieee 1 of 10 cells is dead. I need to replace it like you

pro2 ?? check my latest video on this (pro2 battery repair 2) and try charging that bank up first there might be a BMS fault killing these banks ...
