Hello, I have a couple of Phantom Batteries 2200 mAh 11.1v 20C 24.2 Wh and I am wondering if could use them with my 3DR IRIS+
I am attaching photo of both
The battery for the 3DR Iris+ is 5100 mAh, 11.1v 8c
I do not know what the letter "C" stands for and am afraid of trying out and messing my drone.
Thanks in advance
