Two weeks ago while on a trip in the Philippines I was flying my Mavic Pro. I was out about a Kilometer when I got a low battery warning, so I let the Mavic return home. When it landed the battery was at six percent. When I took it out of the mavic it was quite swollen and had not been before. I thought maybe it happened because it was drained from the long flight. I put in another battery for some more flying. I landed with between 30 - 25 percent charge left. I removed the battery and it was a little swollen too. Never before. I flew my third battery and when removed from the drone it was not swollen at all. After cooling down the second battery returned to normal. No swelling. The first battery that was very swollen was not as swollen, but was still a little. I charged them all up and then did a battery status check on each in my Drone. They all charged up to 4.22 volts. I still get the same flight time from each battery between 18 and 20 minutes coming home with about 25 percent left on the battery charge. Now after each flight the two batteries are swollen, but the swelling subsides after cooling down. The first battery that was the most swollen is pushing agaist the battery locks after flights. When I squeeze the battery it feels like the swelling is air inside the battery. There is no squishing or hard resistance. It is strange to me that two batteries swelled within minutes of each other. I am sure that they were never swollen before, I would have noticed. The temperature was around 90 degrees and the Sun is very strong here. My Drone is hot to the touch after flights.
Any thoughts on my battery stuation?
