Hello,
Today after flying my P4A I saw a black area in the battery compartment. I looked at all 3 batteries, and saw the same black area on one battery. While flying, I didn't notice any unusual behavior from the battery or while charging it, and it is not swollen. Does anyone know what it could be? Thank you.
