Hello all,
I fly my drone a lot. I noticed silver stains between my battery and drone. Could one of my batteries be broken or about to explode?

Please see the pictures.

Never seen that before.  Does battery have any cracks?

Wow! You do fly “a lot” those are just marks from putting the battery in and out. It’s also possible that the battery has swollen making for a tighter fit. Does the battery look or feel puffy?

is it like over heat or something

Inside the drone, where you see the black ink or goo(picture with white rectangular box), there should be a label there if its like my P4A.

What happened to yours or did you never have one(is it residue from the label) ?
