Hello all. I just got my new Mini 2 from Amazon last week. Have been careful to get educated about proper pre-start requirements and registration. Batteries were all fully charged for first time flight. Before my first flight, I sat with a battery inserted into the drone, and the drone powered up, while I watched one more preflight vid on Boobtube... When I went to fly the drone, I noted it felt warm, even though there was no other activity than briefly turning the rotors on then off again. The first flight was a thrill, but I noted that the battery life was only about 15 min before a low battery warning. Two other batteries with the fly more combo lasted the expected tile length. Second charge cycle now shows the battery in question will not take a full charge in the multi charger. Have tried different positions in the charger, no change to th two blinking LED light display on the charger. Putting the battery in the drone shows that it is receiving some charge, as indicated by the powering up of the drone. Have contacted DJI on this, and they recommend returning the battery for analysis and potential replacement. Before I do this, I was hoping to get some input from this experienced community. Thoughts? Experiences? Solutions? M2M
