I used the battery from my Phantom 3 for the Osmo X5 for some time.
The battery has less than 50 charge cycles
she was OK in the last week. I used the Original Charger Phantom 3
Now I took it out of the case and saw that it was swollen and did not react to the charge. And shows all extinct indicators.
I was counting on a longer use for the stated 300 cycles
Any of your ideas.

Hi there. thank you for reaching out and we're very sorry for the Inconvenience. Regarding that, if the battery still under the warranty which is good for 6 months I would recommend to reach out one of our support channels just go to this link https://www.dji.com/support in order for you to have an assistant regarding with the concern.

Wow didn't know you could use a drone battery with the Osmo

I have an adapter that I can use my Mavic Pro battery, as well as an adapter that uses the OSMO charger for my OSMO Pro.  It's pretty nice, especially if you use an external mic and the Focus Handwheel.  It lasts much longer.

The battery with this cord allows shooting for a long time
Unfortunately, the battery was purchased a year ago. And apparently is not under warranty. It's a shame to get substandard products
