We don't compete with voltages lower than that (no load voltage) so we didn't feel it necessary to drop them that low. Maybe we should be lowering the cut off voltage.

In 2009, our battery voltage would drop down to 7V after a heavy match, and under load, during the match, would display around 6V. We came very close to a brownout.

Of course, we were using 9 or 10 motors that year, and they were always on 85% of the time.

But its definitely possible to have the robot operate at dangerously low voltages, so it might be relevant to test the battery down to low voltages.
