Since we're on the topic of batteries... I accidently discharged my AW IMR below 3V (doh!), and was wondering what anyone's thoughts are about that...

IMR's are fine down to 2.5V. With a good charger (xtar, Pila, NiteCore) they can be safely brought back from 2.0V with no danger as long as it isn't habitual.
