Sounds like you haven't finished completing the firmware upgrade. If you have more than one battery when you upgraded the firmware, you need to upgrade the spare battery. Put the spare battery in the drone, turn everything on, go into the front screen of the dji go app and wait for the inconsistent firmware message to pop up. It might take a minute or two for the message to appear. Slide the message across the screen and it should update the battery. Don't go into the camera view whilst waiting for the message to appear.

Hi tevek,

Thank You

Hi Tevek,
I tried but I am not getting any message to update the battery... Any other solution?

Are you using dji go4 and what mobile device are you using?
If you wish to downgrade your firmware, go into the front screen of the app and at the top right hand side of the page you need to push and hold the the three lines to view the available downgrade options. You need to be connected up for this to occur, and hopefully you will see the download options.
Not sure why the battery inconsistent firmware message is not showing up at the moment though.

I would install dji go4 as in future the older app may not be upgraded to support your P4. I would ignore the reviews in the App Store as there are literally tens of thousands of people using the newer app with no problems, including me.

You may have a defective battery if it continues to display that error. Possibly putting it in the quad, turn everything on, open up the app, go into camera view, hit the three dots at the top right hand corner which should give you a list option areas to look at. Go into battery view and look at the individual cell information to see if there is anything obvious. If that all fails, might be time to send it back for an exchange. If you updated the battery firmware and you can't see anything obvious in the app battery info, it might be a dud.

Well your cells are sitting at roughly 94% and have 0.2v variation and it looks fine. As for the battery signal error, don't know why it is popping up. If it was me, I would fly the quad at a low height close to me and keep an eye on it and run the battery down to the battery warning. If you are not happy, can you send it back to be exchanged and give you piece of mind?

If you bought the quad brand new, they have to replace the unit. You must have some sort of warranty.
When you updated the firmware on your second battery, were you connected to the Internet with your AC and RC turned on? Did the message 'inconsistent firmware' or similar pop up in the front screen of the app for you to swipe and update your battery whilst in the powered up quad? I think you said you did but trying to make sure. If so, sounds like you can still fly with the other battery and you need to ask for a simple warranty replacement for the second battery as I said earlier.
