I think this controversial issue in this thread is more the ability (or lack thereof) of teams to bring a second battery and pneumatic system in order to charge the one on the robot before the match without draining their match battery. The fact that pneumatic system is charged before a match is perfectly legal. The illegal issue is the using of a second battery pre-match.

<R01> Energy used by FRC ROBOTS, (i.e., stored at the start of a MATCH), shall come only from the following sources:
A. Electrical energy derived from the onboard 12V battery (see Rule <R34> for specifications and further details).
B. Compressed air stored in the pneumatic system, stored at a maximum pressure of 120 PSI.
C. A change in the altitude of the ROBOT center of gravity.
D. Storage achieved by deformation of ROBOT parts.

<R34> The only legal source of electrical energy for the ROBOT/HOSTBOT during the competition is one MK ES17-12 12VDC non-spillable lead acid battery, OR one EnerSys NP 18-12 battery, as provided in the 2011 KOP.

(emphasis mine)
These rules disallow the use of any other battery than the one on the robot. Therefore, it is illegal to charge pneumatic systems with any other battery pre-match. It would be legal to have the system charged before
entering into the queue line EDIT: starting a match , but past that point, it would become illegal.
