absolutely. I also realize that there isn't a combination of common batteries that adds up to 5V and not over 5.25V, and that discharge curves vary widely acorss the universe of battery technologies, not one of which comes to mind as still delivering useful power at 60% of their rated voltage without bleeding all over the battery compartment
