Repairing your DJI Spark battery using a CP2112 HID USB to SMBus/I2C adapter!

- This is just a brief tutorial on how to repair your DJI Spark/Mavic batteries once the dreaded PF flag is enabled by the BMS on the battery, which leads to the battery not being able to charge or be used. My drone might be a couple of years old, but has not flown that much, so I couldn't believe that the batteries were done for. So after doing some research, I found this way to be easiest and quickest method of resetting the PF flag on the BMS, using a CP2112 HID USB to SMBus/I2C adapter circuit board from China and a CCTV power supply with adjustable DC output voltage and the DJI Battery Killer software.

Hey mate, just another thank you from Australia.. saved me having to buy new batteries! and thanks to someone in the comments that said to do the power with a 9V battery, worked a treat!
Excellent - thanks, Jacques. All three of my Spark batteries are now happily charging. For clarity, Pin 1 is clock and goes to the SCL pin on the CP2112. Pin 6 is data and goes to SDA on the CP2112. The batteries were so flat they needed additional power to enable the CP2112 to read them - in my case I initially tried a 9V power supply but it didn't provide enough grunt, so instead with the jumper wires still attached I pushed the battery into the DJI charger - ugly, and needed to press fairly hard (trying not to press too hard, to avoid damaging the pins on the charger), but it worked. The version of battery killer I have also provides three options - BQ9003 worked for me with the process being Read Info, Unseal, Clear PF, Clear PF2, Reset Chip. Just need to watch the screen - if there are errors (for example due to the CP2112 losing connection) just try again from the start.
Thank you for the excellent video! My son and I revived a “dead” Spark battery following your instructions and it worked great.
Thanks so much for this! Just ordered the cp2112 now so looking forward to fixing it.
I tried this on a Spark battery and it worked. At first I tried using a 9V battery, but when I tried that I got the error message "could not perform smbus read 0x00", presumably because the battery didn't give enough current. I then switched to a 9V power supply from a bluetooth speaker and that worked wonders. Now my battery charges without issue
This worked for me, thank you very much for the guidance!
Awesome tutorial, thank you
Hi, drop box link does not work in bio do you have another link for it? Thankyou
got my dji mini 2 to start charging again. Most important was version of DJI Battery Killer software compiled 13.06.2021so that I could unseal and clear PF2
Can you tell me on the mini 3 pro which contacts need to be connected?
Hello
Do you repair batteries if sent to you ? What would you charge for a spark, where are you based ?
Thank you for the video and freat tut but please do us Rush fans a favor and call the board a CP "twenty one twelve" 😄
Do you need the power supply or the CP2112/software is enough?
Can you please correct the download links, they have been truncated with "..." and so do not work.
The download link does not seem to be working. Please help.
The same thing happens to me with the battery, I did everything the same as in the video, but it didn't work. The loading sequence remained the same.
getting error could not perform smbus read 0x00 after connected connecting battery device
Hello. There is the same application but it runs under Win 7.
I have 2 Spark batteries that no longer charge.
How do you make the leads?
I think we all know why DJI brought that feature into their batteries: $$$
serve para a bateria do dji p4 ?
The link please ????
Hi thank you for the video. This method works for my Spark battery. However not on my mavic pro battery. Do you know any other way to do it? I keep getting this error from the software "Could not perform SMBus read 0x00"
slightly different procedure for the Mavic and Phantom batteries
I think I translated it wrong (I'm French)
the DJI Battery Killer software doesn't work on my Windows 7 computer, I have another one but it's an Imac
does it have to 9 to 10 V
Does the software run under win10 or only win11?
I made the connection and connected its charger together and was able to restore one, but my other battery recognizes it and reset its parameters with the software but it still does not turn on its LEDs or charge, what could it be? Is there any way to also know the battery chip? is for mavic 2 pro and the battery model is FB2, thank...
does that work
Link does not work
Please advise
the link to dropbox doesnot work
Super bummed, after getting all the items necessary unable to repair 4 DJI Spark batteries. With all four batteries I get the same error message "ERROR: Could not perform SMBus read 0x00" when attempting to read info, even with the use of an external power supply providing a constant 10V of power.

You need to be in the region of about 10.5v MINIMUM collectively. So it will be at 3.5v each. Battery killer will more often than not fail to clear the PF if each cell is below 3.5v each. Also, its better to charge the battery at about 12.5 volts, up until each cell is 3.6v. This will at least give an idea if cells are ok and at least holding a charge
@@AshrafRogers Thanks for the response, I will give this another try.
Can be used also for Phantom 4 batteries, instead of Texas Instruments EV2300? TNKS
dropbox is not working.
hi, can i use a arduino uno instead of cp2112?
I've done some research and found that it should work with an arduino as long as you're really good at programming them and manage to make the DJI Battery Killer software see it as a CP2112. As far as I can tell no one has published any code for that, so I recommend using a CP2112
这个模块,使用前一定要小心, 最大 5.6v 会烧掉,做个前置保护,万事无忧.
Just saved 3 DJI spark batteries.
What did you use as a power source?
I used a 12v power adapter. I inserted one lead into the center of the adapter prong and taped another around the outside then taped it together. Not a permanent solution, but I only needed it for 3 batteries.@@limbotachyon
please be careful this video will only work with batteries are at 2500-2700 ,because the minute he reset chip voltage was 3400.. and these where close to balance, there are 2 errors you can get, PF, and ss, pf means it just in hibernation, SS means its out of balance, it wont work this ease if you have both SS and PF , and if both a in data, charging will mostly discharge instead of charge, the worst error you can get is 2nd light in blinking while charging
Hi, it seems that I have/had both errors. The PF could be solved but the battery is still not charging and 'SS" is marked red. Any idea how to solve the 'SS' error? Thank you!
@@blacksmithz1 hi, did you respond to my comment? If so, I am very sorry but I don’t understand what you mean :(
@cruzroy, any idea what I can do to solve the „SS“ issue? Thanks!
Any input fit this question?
ss would require opening the battery and manually recharging all cells to balance.
how to edit the full charge capacity? pls help
HOW ABOUT GUYS, SOMEBODY'S GOT THE PROGRAM TO PASS IT ON TO ME
