First off,  If the attitude makes the satellite useless of course someone will
any extreme measures to make it useful. And yes of course it may be so out
of whack that the torquers cannot be useful or even used.

What the hell do you think i asked about using the wheels for?


Now , back to the original question.
IF we had to, would there be enough power without the batteries?
