I am selling adapters for the headplay FPV system. This lipo cable/adapter allows you to use any 2S lipo to power your headplay unit. Personally, I use a 5000 mah 2s lipo to power mine and it lasts for many hours (~4+ hours). I use anderson power poles so I can set these up with andersons or if you use something else (XT60, etc.), I don't have those but I can sell you pigtails that you can make on your own. $5 shipped with andersons. $4 shipped as simple pigtails.
