Thanks, it's very helpful info

[@santiagotrujillo2656]

Is there a chance you can make a debugging board for the TB60 batteries I have 3 dead pairs, not swollen and they didn't even get to 100 cycles (they are supposed to give 200 cycles)

[@moulton999]

Thanks!

[@gregdonnelly6181]

Heh Dave; thanks so much for sending over the software, much appreciated. I will post here results, good or bad!

[@webuydronessa]

Only a pleasure Greg , let us know if you need any assistance

HI i WOULD LIKE TO BUY THE TWO BOARDS FROM YOU PLEASE THE DE BUGGING BOARD AND ALSO THE BATTERY BOARD FOR THE MAVIC AIR

[@tizzzzy69]

any joy with the mini 4 battery's

[@danielis111]

Danke!

[@CarManPhoto]

Will it work with Ronin-M battery?

[@domenus]

Any chance for this to also work with the DJI FPV Drone battery? I have a couple that went "all lights blinking" and won't charge. :(

[@webuydronessa]

Not at the moment , but hopefully in the near future yes i am sure.

[@jumpinghighest]

Hi, you Thank you!

[@bernardharewood1686]

Hi good day, i followed the instructions step by step ,but what i have noticed, the battery voltage for each cell is over 3000mv in the video. I have a brand new mavic 3 battery and cells 4 and 2 read ,1 and 3 read 790 mv . Unsealed cleared the pf and pf 2 , got the first led to blink when i pressed cleared pf2 then it stopped. Any help will be greatly appreciated

[@bobf3598]

On a Spark battery if I get the error, just connect external power brick 12v 1.5A to the LHS(next to SCL) pos and neg pins and let it charge for a bit and the error will go when wired up and connect to software... No need to perform "open heart surgery" with battery.

[@webuydronessa]

Hi @bobf3598. That does work when there is enough voltage in the cells correct. Unfortunately it is not always the case, and the battery will have to get opened to " wake up " the cell if too low. Those pos and neg pins go through the BMS first, so if the BMS has switched off the CHRG/DSCHRG parameters, then it will never push voltage through to the cells.

[@paulwoodfield1651]

Hi Thanks for videos, I'm one of the unfortunates that has 2 mavic 2 batteries that won't read, so I'm opening them up. You say in the video put voltage into to the battery slowly, so I'm sure are you starting with low voltage or amps your not specific with the settings. Thanks again

[@AshrafRogers]

Hi. So for a Mavic 2 battery, I believe max charge is 17v +-. I usually use about 16volts, but minimum amps. I go about 0.50 amps. Slowly get it up to about 14.2 volts (each cell minimum 3.5v ). Thereafter the CP will detect it and is also safe to clear the pf flag as the voltages are above the needed requirement before flagging. Just be careful making sure you have the poles correctly for charging the cells collectively.

[@paulwoodfield1651]

@AshrafRogers brilliant thanks just got one back to life I did 16.5v 0.5amp 30 mins.. if only the cases opened easier, that's the hardest part

[@martinmastronardi6380]

hi.. nice video... any chance to work with matrice 300 / 350 battery? thanks. best regards from Argentina.

[@webuydronessa]

Unfortunately not

[@GULLYGILTV]

do you have to solder the cp2112 debugging board with the pins mine came separate?

[@webuydronessa]

Hi. Did you manage to get sorted with the above? Thanks

[@omegatextilome733]

Hi what about if i want to make battery mode with 3600mha or 4000 mha battery cell,it can be created battery with Mavic Air 2 and 2s cell. Do i need software for the capacity of 3600mha or 4000 mha

[@webuydronessa]

Can be done yes, but only capacity change. You can change cell count but the firmware of the device would need to be hacked to allow no errors from the BMS.

[@reinhardplietsch9707]

Getting SMBUS read error, have tried to power +/- pins from external power supply with 9 and 10V, to no avail. What else to try? Cells seem to be drop dead, stored for 2 years, pbly too low to even let the supply voltage get through to support the cells 😞

[@webuydronessa]

Hi. Unfortunately if is does not hold any voltage at all, then those need to be discarded yes. Depends on the battery and cell count, 15~17 volts is needed to get the 4 cells up if its a Mavic 2 battery. This would allow them to get to the "required" 3.5v per cell which equates to 14v. Then the CP2112 will easily get rid of the PF flag and re-enable charging etc. Thanks

[@dottedgreenline]

Thanks for the video. I have 2 spark batteries that the software sees, but both error when clearing PF2. All other steps work fine, just "Clear PF2" errors and then no change when charging. The software gives me an "ERROR: PF2 is not active" message.

[@AshrafRogers]

Hi. So what steps do you follow?: Read Info - unseal - Clear PF 1 - Seal. After clearing PF1 a light on the Spark battery should slowly flash. Then switch off the battery in which the led light on the Spark battery will flash rapidly, indicating successful reset of the BMS. Then put the battery back on or put on charger. If you clear PF and you dont see the light flashing quickly, clear it again. Also Note, the voltage of each cell needs to be 3.5v at least for the PF to clear successfully. So total voltage minimum 10.5v minimum

[@user-te8bj6gw5f]

When connecting the Mavic 2 battery and the CP2112 communication port, a message like this (ERROR: Could not perform SMBus read 0×00) appears and the connection is not possible.

[@webuydronessa]

Hey. Apologies for the late reply. Have you managed to sort it? If not, you might need to give the battery a small charge with the original charger just to " enable " it. This only needs to be plugged in for 5 seconds or so. Thereafter unplug and plug back into the CP2112 board and check. Failing that, the cells might be too low for the bms board to function. The cells should ideally be 3.5v each. This can only be determined by opening the battery itself and manually checking each cell. If you are still stuck, give us a shout. Thanks

[@mathieuhenrissat1449]

Hello, please what is the name of the cable/connector to link de card ev2400 to other card ? Where I can buy it ? Have you got a link ? Thank you

[@AshrafRogers]

Hi. The ev2400 can only be used with TRB software, which no longer exists. The CP2112 board is a fraction of the cost, and the software needed as in above video works for almost all models anyway

[@angelvaca9232]

I made the connection without opening the battery and connected it together with its charger 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 for mavic 2 pro and the battery model is FB2

[@gvibes69]

Guys !! dead batteries you only need to disconect the cable from the cells that go to the board or if its soldered , desolder it and solder again !!! I done that to many old fimi v8 2018 versions !!!

[@webuydronessa]

This does NOT remove the PF Flag on the BMS board , this method has to be done with DJI batteries , if you do not remove the PF flag the BMS board will not allow any voltage into the battery , yes maybe your procedure works on other brands but not DJI

[@Djalma_Junio]

Hello friends. I bought a mini 2 and after the first flight I went to recharge the battery and the following message appeared: "Battery error. Contact DJI support. ERROR 30074" Also appeared: "Battery cell damaged, discard battery and contact DJI support. error 110004" That's why I came here and purchased the items to try to recover my battery that wasn't charging. I managed to carry out the process in this video but unfortunately I think that there is no solution for my case. Because 2 cells are dead for some reason. Battery Cell 1 Voltage = 4079 mV Battery Cell 2 Voltage = 4308 mV Battery Cell 3 Voltage = 0 mV Battery Cell 4 Voltage = 0 mV Does anyone know if it is possible to do something in this case?

[@AshrafRogers]

Hi. Apologies for the late reply. No, the mini 2 uses a 2 cell battery, so it showing 2 cells @ 0v is normal. The problem you are having is you need to balance those cells. 4.3v and 4.0v is a big difference and the BMS will activate the PF flag every time. Once those 2 cells are equal in voltage, then that battery should be ok. You will need a balance charger to do that
