Ah, but it is possible.
The RC will resort to the backup battery when the 12 volt supply fails.
Since it won't START using only the 7.2v, all you need to do is fool the RC into thinking a 12v source is there at startup. A fresh 9volt battery just touched to the 12v terminals will fool it into thinking a somewhat drained 12v battery is actually being used. That's how we normally started our RC in the pits to drop in program changes when we didn't want to power-up the whole robot, i.e., when the drivetrain was under repair at the same time.
