Safety is forever, not just on the field.
I wish I had a nickel for every team that has told me that they think it is OK to connect the compressor to a battery and then disconnect it when they think it reaches pressure. I could buy a better laptop with that change.

You are completely correct. The original question stated the battery "was plugged into the robot" to charge pneumatics. I was assuming the compressor was under cRIO control. I see a lot of things that I would consider unsafe every year and pre-changing robots in the queue lines one of those things. I think there should be a place to do those sorts of things right before you take the field. An on deck circle perhaps? But this not the place to discuss this.
