Looking for advice. I just bought a P4P in excellent condition from Adorama. I turned the drone on and the following message popped up on my phone, “Battery cell broken return to factory.” Then the drone shut off automatically.After that I fully charged the battery and it seems to be working. Does anyone know if the battery is safe to use? I did checked the battery and it one of the battery cells is 0.02 volts below the other cells. Would that cause the issue? Trying to figure out if this battery is safe/if I should return this battery. Thanks.

One thought would be, is the cost of a battery worth the cost of a crashed aircraft. Your battery may need more testing on the ground to make a decision on how airworthy it may be. Too many variables to know what caused the battery issue.

Adorama service is pretty good but might transfer you to DJI. Worth a call and if needed get a return label. Might be that cell drops out as voltage drops. Not enough amps to fly. Not a pretty ending. Logs will show the warning so they may not honor the warranty in a crash.

Friend: Responding to your query I think that after seeing that message in the App, I suggest you spare no effort and return that battery, I think it is not worth risking your P4P for a battery, the price of your equipment is not It is worth it for a battery that after that notice ... does not inspire confidence. On the very small difference between cells it is not an indication of failure in any of them, with 2 or 3 Volts it is already to worry. Do not think so much and follow my advice, return the battery and change it. Greetings.!.

Flew the P4P 2 today and noticed that one of my two batteries had 4 fairly small cracks in it but certainly noticeable. All 4 cracks were in that removeable "Cap" that is exposed when you plug it into the drone. there was one on each side and two on the curved top near the power button. I have always been careful with these batteries and none have never been dropped.
When testing it today, I kept it over land and close to the ground. All went OK but it did seem to discharge faster than normal. What causes these cracks and what do you guys recommend. I have a phobia of the bird losing power suddenly from a failed battery and turning my Phantom into a post hole digger.
