In flashlights (etc), Li-IONs are often pulled down to 3.00V. It does not have any great advantage because it goes down from 3.3 to 3.0V pretty quickly, but it is not completely insane. Actually, under load, it may make sense: internal voltage will be higher at that point. Best regards, Pavel --=20 I don't work for Nazis and criminals, and neither should you.
