Air 2S won't power up and connect to controller.

[Mike49]

When I start up my drone the batteries are fully charged. The battery lights flash, but the light on the legs do not. I try to connect my controller to the drone and it just keeps beeping. Any help would be appreciated.

Clean the connectors for the batteries. Drone and Battery.
Update all your firmware..Controller Drone and Batteries.
If these 2 don't work your batteries are damaged and need replaced.
