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.
