I have a question that may be dumb to all of you but its my question and I hope someone can help me.
Theoretical example
The basic question is if you have a DC device that requires a minimum voltage of 7V and you use a battery pack that operates at or just above that voltage will it run longer or shorter than a battery pack that is higher, such as 11 volts or higher?
Actual example
If I use a lithium polymer battery pack (2 6600mAh cells in series for 5.6V to 8.4V) a to power a DC device that has a voltage input of 7v - 24v will I get a longer or shorter run time than if I use a 11.V (8.4V to 12.6V)?
I realize that it may depend a lot on how the device board is laid out. I also assumed that a higher voltage may be just burned off by the device and provide no value to run time.
Any information will be helpful
