If they use battery cells ranging from 14500 - 18650 series, they will operate at 3.7-4.2 volt. Cameras w/ two cells will operate between 7.2-8.4v. The voltages are a game of marketing, and the extremities can be seen between DeWalt (20V @ 5 cells) and Milwaukee (18V @ 5cells) toolsmAh figures are not comparable if you don’t know the voltages. mWh is what matters.
