I tested the unsealing on Mavic 1 battery I have, and it was working. Why it didn't worked for you - I don't know. Maybe unseal key is different, and maybe the issue lies somewhere else.

[mjnhchj]

that's right. I can't do it with my MM battery either!

[mefistotelis]

When you figure out the cause, make sure to share.

I used this tool https://mega.nz/file/yEJGwJYR#O3jh40agtSWE11HRySdg5C6X5y2OeHW2c_A4hOcCVFs All work fine with CP2112 adapter

hello everyone, how good there are enthusiasts who can embrace almost anything. this topic helped me check out some AIR 1 batteries that I managed to buy some time ago. However, I have a problem with sealing. The program presented here does not have this option, but it is in the last screenshot. What is this version, because visually the interface looks identical, it is probably a newer development version. There is a chance to get access to this version? I have one more question. Has anyone tried to replace cels ( mavic AIR 1) with more capacity, but not 18650. I am asking because I noticed repeated damage that the last cell in blocked batteries has reversed polarity and cannot be regenerated, charged. Thanks in advance for any suggestions.

That software is "DJI battery killer" by Mixeysan developer! It will release soon ...

I have not finished everything yet. In particular, still need to remove the unnecessary and disable to write of FW BQ30Z55, because the CP2112 adapter will not be able to do this anyway. But the change in capacity, voltages, charge max, reset of cycles seems to be plowing both on bq30z55 and on bq9003. To get full access in BQ30Z55 when the key is unknown, use the Full Access button. There are still small shoals, with time I'll correct it. And I'll release it a little later when will be free time)

During the test, repairing the firmware in BQ9003 when the EEPROM is empty - FFFFFFFFF. The chip is always in bootloop. See video http://master-club.org/drone/BQ9003_bootloop_repair_empty_EEPROM.mp4

Check your files or system. You are the first who wrote about such a problem

Hola Sr.mixeysan comprando el adaptador cp2112 como debo conectarlo a la batería del mavic2 alguna imagen como esta

[0roblequad]

donde conecto el sda y scl en el pc2112

[SinisterRj]

@0roblequad Usually the boards came with those pins labeled. Check with your cp2112 vendor. (you must connect gnd pin also)

[davidhaluska]

Hi All, Is there possible to put battery into sleep mode - as when it comes from factory? There should be some command for that or? Thanks. David

[Alessandro2023]
