While flying today I received a Defective Battery notice in the upper left corned of my screen,  This is the second tine this has happened.  I was at 80% battery and brought it home.  I rebooted my controller and the problem went away.  I flew again with the same battery to about 65% and all was OK.  I flew again with my second battery and all was all right.

Thoughts?  Do I have a problem with my first battery?  Thanks

Got a similar message two weeks ago on a P4P+. “Battery Damaged” Was so freaked out, I forgot how to take a screen shot. I pulled up the battery monitor and saw that 1 cell was .3 volts less than the other three. I ran the battery down until it turned off by holding the aircraft and giving it a little throttle. I then charged it up and tried again. Same thing. I repeated the discharge and recharge and it still failed. I ordered a replacement battery from Drone Works as it’s getting harder to find actual dji Obsidian parts at the original price. When I have free time (absolutely zero possibility this week) I’ll put the bad battery back in and try to get the message up. I remember I have to swipe up to get the screen shot... I’ll get all the particulars when I get the screen shot. I seem to recall it had around 30 charge cycles but I’m old and can’t remember for sure. I do know this one thing for sure, this battery will never fly in my Obsidian again. I’ve read bad battery horror stories that resulted in catastrophic piles of broken plastic, and I’d rather not have to type one of them myself.

Follow up:

I charged both batteries to 100% and ran them both down to 10%.  The problem did not repeat so I will chalk it up to an aberration.   I will watch for a repeat in  future flights.

Can anyone tell me if you can take a  screen shot with the P4P  pro+ v2.0 and how?

If it's not possible with screen, try to connect your cellphone, and print it out. It's a idea!

“Battery Damaged”

May well have been the message I received.  I was going from memory since I don't know how to take a screenshot from the pro + screen.

If I'm in the air, taking a screenshot is he last thing I want to do in this situation, I recommend tracking your cell health.  AirData has a nice graph showing this, fortunately in this case I found it when bringing it out from storage and prior to any flight...

It’s only a button click away... haha


Yeah, I’d likely get that feeling too, “Anx”!!

If you swipe down from the top of the screen, there will be a capture button in the middle/bottom of the dialog box that appears. Later, connect your controller to a pc or Mac using the USB cable. Big end to computer, small end to the small USB connector on the + controller. Enter the settings page then swipe down again. There will be a message at the bottom of the dialog telling you USB connected, touch to enable. The next dialog that appears will allow you to turn on USB storage. As soon as you select that it will connect to your computer. Open the folder named “screenshots” and your captures will be there.

I take screenshots all the time when I’m flying. I just haven’t been flying a lot lately due to work and I just didn’t think of it when the message appeared. I put the bad battery in the acft and couldn’t get the message again. I’m recharging it again and I’ll try again this weekend. As soon as I see it again, I’ll take a shot of it and post. I’d like to be more help, but this is a very busy time of year at work.

You can see the bad cell is around 6 tenths of a volt lower than the other three. The bottom battery is a good one in flight.

The aircraft won't start. I was only able to get the screenshot of the warning by trying to start the motors.

It is odd that I received the same battery cell damage warning but when checking but when checking the cells in flight after the warning came on they all read the same amount.  I will watch it for a while before hitting the panic button.
