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.

Thank you, with you help I was able to bring my Spark battery back to life. I ran in to a few issues along the way but thanks to online forms like Grey Arrows Drone Club in UK I was able to get answers to my questions surrounding issues like not being able to connect to the board and not having a power supply handy (just use a 9V battery). Thanks again Jacques. PS I subscribed as a thank you.

[@steven.h0629]

❣❣ Thank you Jacques! I have four Spark batteries that went flat like yours. Exactly like you've mentioned in your opening, most other videos yammer annoyingly on and on without actual instruction, yours is the absolute best!!

[@fefillo21]

Thanks for this video! I just received my board and revived 3 batteries with your instructions!

[@mikefoster5552]

Thank you for the excellent video! My son and I revived a “dead” Spark battery following your instructions and it worked great.

[@richardaphillips]

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.

[@CireWP]

How did you get 3 options? Mine currently isn’t reading the battery and I tried it on a working battery, still so signal

[@aidanhughes3655]

[@garciaicrag]

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!

where did you find spark's batteries to buy?

[@Nashville663]

Thank you so very much for your Clear explaination & coverage in how to rescue my Spark battery showing the same issue as you clearly described. The best instruction by far. 10/10 Many Thanks

[@michaelmendoza6787]

Just followed these instructions with a 9volt battery and it works! Fixed two spark batteries. Thank you so much!!

[@Kiiohru]

Im waiting for my cp2112 to arrive and try this Did u use an adapter with 9volt battery then straight up connectted it to the spark battery?

Hello Do you repair batteries if sent to you ? What would you charge for a spark, where are you based ?

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

[@ronnor58h]

Where did you download your software from? I see many people talking about having virus warnings come up when they try to download their software. I have a brand-new PC build, and I do not need any troublesome software on it. Thank you for the video, Liked and subbed

[@brunoraw755]

Good evening, do you have the schematic for DJI Min 2?

[@jefferyryan7232]

I’ve tried this with the software, but I don’t have anything similar to your power supply. How can I ship my three batteries to you from Canada?

[@dcippitelli]

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.

[@AshrafRogers]

kzbin.info/www/bejne/Y3LJZn-vhsaMgNE 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

[@dcippitelli]

@@AshrafRogers Thanks for the response, I will give this another try.

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"

[@aeresys]

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

hi! thanks a lot for your video. can you share the mac os version of the software with me please? thanks in advance

[@yvngmirvti6676]

hi, can i use a arduino uno instead of cp2112?

[@aeresys]

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

[@GRIZZLEYSTEVE]

Anyone have a working link to DJI battery killer please ?

[@UndirH20]

I did this using a brand new 9v battery as the power supply. Worked great! Just sayin. Sadly it's been a few years since I flew my drone and thats why the batteries were dead in hibernation. The DJI GO 4 app I use to fly the Spark is not supported on any iOS phones after iPhoneX. The app was super Wonky on my 15 Pro Max and I could never really get back in the air comfortably. Ended up buying a newer drone in the long run

[@195638]

Hello. There is the same application but it runs under Win 7. I have 2 Spark batteries that no longer charge.

[@thierryannicette6480]

does it have to 9 to 10 V

[@195638]

Does the software run under win10 or only win11?

[@softa74]

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.

[@angelvaca9232]

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...

[@CRUZROYHelicopters]

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

[@d.becker8195]

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!
