Would the voltage of a power source decrease if multiple loads / more load is added to it?
I am researching battery types, and wanted to know, if I added enough load to a battery how much / would there be any voltage drop?
Example: I have a 12 V set of batteries in series. The batteries' rated current is 48 A.
I have four loads that each require 12 V and 13 A of electricity. Would there be any voltage drop, would the load have to be significantly higher to actually see a decrease, or would the voltage stay the same?
