I have recently bough DJI Tello. Its awesome small drone with good camera but not that much good. I needed more quality video thats why I am planning to use Firefly Split cam which is just 20gm. You can check it at below url

What I need to know is which battery will be perfect for this cam. It will need 2S battery. I need battery which has minimum weight like 20gm most.

Best Regards
