XIAOMI PRO2 Battery - Repair 3 [Manual Balancing & Full Checkup]

The scooter had 3700km at the time of this intervention - around 1500km of which were done in brutal summer conditions going up hill with a load of 130KG on the scooter - so, flat-out 1000KW 30 minute runs.

Check my previous interventions on this battery if you want to know it more intimately.

I also updated the BMS version 128 back to 141

po 7500 km bateria się rozjechała. Różnice napięcia na nawet BMS 0.5V. Składam teraz z używek baterię 10S7P . powinna się zmieścić w hulajnodze. Zakładając po 2Ah na ogniwo to wyjdzie około 14Ah. Przy 7 równoległych prąd będzie dużo mniejszy niż dla 4.

hello how to remove bateri from the bunkier?

[Maraxion]

Any news on this, have a similar problem.
Also do you recomend a certain bms version firmware?

[carlh]

have you thought about adding an active balancer?

[ainaras]

hey . Xiaomi 365 pro (or pro2) battery is 12, 8 AH = 3200 mAH x 40 cells ?? Is it right ??

[darioantinoro]

Hi please continue with these videos! I have the same problem and i think i am going to charge manually the 2 cells that are lower than others(i have a min/max of 0.13v). Can i charge them soldering a wire on the metal part where you put the multimeter? Or it's worng?

[bobbis]

Oh god not again lol. Im rocking a ninebot MAX nowadays and treating me well. I've beat the shit out of this thing and no complaints. Hope all is well brother. Oh i got a TS80 Soldering iron for $50 on arduino, i think they are still on sale if you are looking. theres another one, the Penelin? on sale as well for like $23

[Blaszow]

Is there datasheet for this overvoltage protection chip?

[jorgerodriguezramirez]

hello! how did you spoofed the controller ? I tried to imitate your testings but I got a hall sensor error.
Edit: I see the answer in another of you videos, too much complicated for me. Will be great sharing a video of this as nobody in YouTube Has done

@darieee wiesz dlaczego nie świeci lampka z tyłu???

[RomanRomanov-bjey]

hello, if you know, tell me what model bms is used in this battery? vendor code

[innerfirepursuit]

There is a way with a custom firmware to switch on the BMS of this battery to use it for a bike or something else? Thanks 👍

Не могу понять зачем Вы дурью занимаетесь? Все аккумуляторные батарейки надо заменить на новые samsung или panasonic.Или вам нравиться каждую неделю его разбирать?

[ManSki]

Just out of curiosity, it has been a year or so since last video. I guess there were no more manual interventions done to the battery?
Ot would be great to hear back from Darieee. @darieee
