Just received my Phantom, plugged in both the battery to charge, thought it would stop blinking when full, but did not. I unplugged it, and the lights still blink, tried toshut it off, but it won't shut off.  Just keeps blinking.  Plugged it into the unused drone, seems to go through a start up procedure, but still blinks.  I removed battery, and still can't shut it off.  Any ineas?

Maybe just to clarify further.  I did plug in both the controller and battery at the same time.  Controller was blinking during the charging process, then shut off when done.  I then unplugged it.  The battery continued to blink, indicate it was charging, so I left it and went to bed.  6 hours later, it was still blinking, so I unplugged it, and its still blinking, can't turn it off.

Unless something has changed, you should not attempt to charge the controller and a battery at the same time. Not sure if that's what caused your battery issue though.

Two things. Have you tried holding the power button to essentially "reboot" the battery? It has intelligence and may be locked up. Also, are you able to update the firmware of the battery by starting the drone and controller up and launching the app? I think if the battery is in, and you connect the Assistant app on a PC to the drone via USB and do an update, it would probably update the firmware on the battery too.

Could you happen to provide a small video of what you're getting?

I resolved this issue.  I had not yet flown it.  After 12 hours or so, of the battery blinking on it's own outside the P4P, I was still not able to shut if off.  I powered up the controller, put the blinking battery into the P4P, and the P4P fired up (first time).  Got wifi established, then proceded to take a firmware update.  After being stuck at 99% for a few hours, the controller went to sleep, but the P4P was still blinking, and I could not shut it off.  So I removed the blinking battery.  I restarted the controller, put the blinking battery back into the P4P, established connection, and received a message of a sucessfull update!  Then, I could finally control the shut off of the battery, press the button once, then again for 2 seconds.  Works like a champ.

Now I can get to understand the system, and all the information on the controller, find out whats necessary before my first flight.  Thanks for the comments,  No internet bashing here.

theGrindLab, could you please expand on you statement, I may be reading it wrong but I often charge a battery and my RC at the same time, am I wrong for doing so??

The statement is correct, you should not try to charge both a battery and the RC at the same time, it exceeds the capacity of the power supply. The 'charger' is not really a charger at all, it is simply a power supply. This caution used to be mentioned in the manual but does not seem to be in the latest manual.

Thank you, I will now change my charging procedure..

In the Phantom 3 series, the manuals indicated charging the controller and a battery at the same time should not be done. I am not sure if this has changed since the Phantom 4 series was released.
