You have to have an extra battery for the karma. 18 minutes of flight time per charge is pretty good for the drone's size but not long enough. The only hitch is that, and maybe this was just me, then first replacement battery I bought didn't fit into my drone. I bought a second and it also didn't fit, but I noticed it was just barely not clearing the plastic of the drone's shell up by the charge indicator. I cut a millimeter off of the plastic on the drone and the battery fits fine now. In the files uploaded the picture with the orange sticker is stock, without is replacement. The left side of the photo shows the closeness.

You gotta have a couple backups! The GoPro Karma always keeps you wanting more time to fly around and get awesome images and video!

The whole drone ,camera every that I bought I like it

Your gonna want to pick up a few of these to keep your drone going. you get anywhere from 15-19 minutes flight time. so pick up like 2 for extended flights. you can also use a fully charge battery and the hookups to charge your gimble and camera.

I purchased this battery along with my karma drone because, I wanted to fly my drone more than the 30 min provided in the first battery. I’m glad I purchased it because, when I fly I often fly for 45min to an hour. I would give this review 5 stars however one feature which I disapprove of is, if you just leave the battery sitting for a while it uncharges itself. I have to constantly make sure it’s fully charged when going on a flight.
