Pixhawk 2.1 power brick

Hi, I have a new power brick which came with Pixhawk 2.1, Which connector is for the battery (input) and which one is the output to be connected to ESC’s.

Thanks

Do you mean “which of the big yellow xt60 connectors is which?” If that’s your question, take a look at this picture of a battery:

And this picture of an ESC:

From thinking about the xt60 connectors as shown in the pictures, you’d see that the battery plugs into the connector pictured on the RIGHT side of your power-brick picture, and the ESC would connect into the LEFT side.

Hi hunt0r, Thankyou very much.
