ESC Calibration Failed PX4

I have a pixhawk 4 running through QGround control on windows 10, when I click on the summary, everything is green and seems to be set up, but my ESC’s aren’t set up, and I’m pretty sure they need to be. When I click ‘calibrate’ it says “calibration failed, battery unavailable” even though I have my battery plugged in.
Can anyone help? This is my first time setting up a drone.
