Xiaomi vacuum cleaner battery repair

In this video i'm restoring xiaomi vacuum cleaner battery

[jan]

My vacuum died again and now i had 2 dead batterys laying around. Saw this and figured i might combine all good cells to make 1 good battery out of 2 dead ones.
Was my first real soldering job i ever did but i did it and my vacuum works again. Thank you!

*A great vacuum for the price. The suction is awesome. Excellent for pet hair. The beater attachment works great **MyBest.Tools** on the stairs. Not too heavy and easily maneuvered.*

Thanks, worked like a charm! My battery pack also had 2 dead batteries. Voltage of the pack was bellow 10v and the robot just died everytime it left the dock. :)

thx for posting this. i've always wondered what to do if my batteries can't hold its charge in probably 2 yrs time.

Good job! See the dance of a vacuum cleaner at the end. She is so happy now.

Yesterday I noticed mine died too. I was about to buy a new battery when I saw your video, gave it a try and it worked :D Thanks man! Except mine had a ton of glue inside so I had to chop the enclosure to pieces to get it out.

The navigation system is great🌼 with the fact that it does the mapping of the house and knows where it passes does not leave any corners unclean and also saves a lot of time because it does not have to go over several times on the same points.

Is it possible to put the batteries from a 1T or 1S into a 1C ?

I have a Niato robot vacuum cleaner. The battery protector of the vacuum cleaner does not work. What is the solution?

[srkanAGA]

I have faced with error 14 after changing all the batteries with the new ones. Is there any solution to this

Hello, I have a question.
My robot starts cleaning with 100% of battery left and the last 4-5 times when it arrives to 40% it dies suddently.
Before when the battery percentage was low it returned to the dock in order to recharge itself and after that it starts again, but now it stops itself in the middle of the room without any voice message.
Do you think that could be the battery pack that is damaged and it is necessary to replace it?

Viomi Alpha UV(S9) remove all the main screws, on back of the robot vacuum, and then lift the lid from the front to access the battery, as per Xiaomi.

Thank you.

Hello, thanks for such a useful tutorial. May i ask, if we replace all 8 batteries to LGABB41865, what will the capacity be? Since each LGABB41865 is 2600mAh, will it be a whopping 20800mAh and can the roborock last perhaps multiple times longer than the original xiaomi battery? Thanks for answering

[manuelassouad]

What is the link to buy the entire battery?

[ChibiKeruchan]

why mine just doesn't come up.. it feels like it was glued inside

[ukaszlipianin]

Hello and thank You for Your work!
Is there any chance that You can share a macro picture of the battery board, especialy the B2 compartment. I just put out some resistors with my screwdriver when opening the case and now
I need to solder them :D

[xkzt]

how do you remove the top cap of the battery case? yours was already open

[knightrider]

I am trying to make a battery from ground zero, I bought a 4S BMS PCB, and 8 cells. Could you please tell me the pinout of that battery cable going into the vacuum? I assume, black is GND, red is VCC. What are yellow and white?

[wilkas]

Doesn't solder heat damage the li-ion battery?

[sergeiboyko]

Is there any chance that LGABHG21865 or LGDBHG21865 can be installed instead ?
