Fytoo 3pcs3.7V 400mah Lithium Battery for SYMA X22 X22W Four-axis Aircraft RC Quadcopter Drone Battery Spare Part White

I felt at first time that they maybe won work, but i was wrong, they work very well. They get long using them in my drone for 5 minutes continuously, and they took 90 minutes to get re-charged.

These batteries fit my SYMA camera drone well and give me 7-10 minutes of powered flight.

I bought them to have some extra batteries for my SYMA X22W. One battery didn't fit in the drone at all, But I figured I could at least use the other two. I used one battery and the flight time was about half of what it should be, maybe 3 minutes. Popped the other battery in and same thing. Went to use the original batteries that came with the drone and now it won't power up with one of the original batteries and the charger won't charge that battery either. So now instead of five batteries I have one. Very disappointing since it looks like this may have ruined my drone because I don't think it was a coincidence that my charger and two original batteries stopped working the same time I used these.

Good
