After resetting the ph4 battery using the Dji battery killer again, there are errors in the bite register (XCHG, XDSG, SEC1, SEC2). Help!

[dulshanjayasinghe12@gmail]

Hello everyone,
I recently recharged my dead ph4 battery using a balance charger, and the battery holds voltage perfectly fine(around 3.9 for all 4 cells). After that using cp2112 to connect the board to DJI battery killer software I was able to reset and remove PF flags but never able to remove these flags (XCHG, XDSG, SEC1, SEC2) also after hitting the read info button on log value (0C)Max Error = 1%
Shown.
Also, I plugged the original Dji charger into the battery, and the battery charged normally but after plug into the drone, the drone did not start (no beeping, no sounds nothing) also battery shut off around 5s (after plugging into the drone and start battery). Please help!

I'd suggest reinstalling battery firmware but apparently it won't stay on long enough to try. Battery updates while refreshing drone firmware.

I figured out what happened and now the battery is connecting and also drone starting normally but cannot take off (shows battery authentication error)

Did you update battery firmware by refreshing drone firmware with battery installed? If so, no other ideas

yes
but the same results nothing change
anyway, do you have Phantom 4 battery eeprom and firmware?

Hope you get better results on the other forum

I did not know that there was firmware for the 4 V2 do these automatically update when you do a firmware update iam not sure how this is done can you please fill me in on this thanks very much

Hello, can you please provide some guidance on how you got this far.
I have the version 0.5 Beta software and the CP2112 card. It is all hooked up to my Phantom 4 battery.
The software can connect into the CP2112 card. (I manually charged the battery to 15V) and it holds.
But I can't get the software to read or talk to my Ph4 battery. Can you tell me how to get to where you got to?

Hello,
Is the DJI battery killer even designed to work whit Phantom 4 (Pro) batteries?
I have a Phantom 4 Pro battery that most probably have the PF flag set, I would very much like to try this tools if there is any chance that it could work.
But I will not put the time and money on it if there is no chance ....
I already have opened the battery pack and have charged it with an external charger(now at ~15.2V), but first LED blinks 4 times when pushing the power button.

Taiger, did you remember that you click and click hold the battery, not just click?

Yes, I have tried to do this as well. When I do, the power button is lit up and the LED furthest away form power button keeps on blinking (like 1 second blinks)
If I then put it in the DJI charger noting happens, it keeps on blinking like before. With a voltage meter I check that the voltage does not increase (no charging) on the +/- pins.
If I power of batter and put it in the charger the Power button LED turns on and the LED furthers away from power button blinks a lot faster like 15 times then everything powers off. Then it is off for ~8s then it repeats the 15 blink cycle. This continues forever basically, and voltage on main power pins do not increase.

When I first opened the battery pack the voltage on main pins was down to ~6.2V, after manual charging it was up to 15.2V yesterday. But today it is down to ~14.8V

Even if I got this to look like it's OK, I sure as hell wouldn't fly with it. Not worth the risk. Check Amazon for replacement batteries.

That would then be the next thing to check if I got it working. I have other batteries, but I'm very curious if I would get it back in operation.
If I would get it to work in the drone I would start by testing it with like 10cm above ground until battery is drained again a couple of times.
After that I would evaluate further if I would risk anything more.

So any info if the DJI battery killer is theoretically working with the Phantom 4 Pro?
