What voltage can a battery provide?

Battery cells provide higher voltages when they are fully charged and lower voltages when they are depleted. However, if a device requires a constant, regulated voltage, it cannot be directly powered by a battery cell. Instead, a voltage regulator must be used in between.

USB power banks come equipped with built-in voltage regulators, providing a constant, regulated voltage. However, most household and industrial batteries, including V-Mount and Gold Mount batteries, do not have voltage regulators.

The highest voltage a battery can provide is typically very close to the charging voltage. For example, Globalmediapro V-Mount batteries are charged with 16.8V and their highest voltage is approximately 16.8V.

The lowest voltage at which a battery will switch off is called the "cut off" voltage. For Globalmediapro V-Mount batteries, this typically occurs at 11V.

The nominal voltage indicated for V-Mount batteries is usually 14.4V or 14.8V, which is the average voltage produced by the battery.

Cameras, camcorders, and other devices that are directly powered by batteries have built-in voltage regulators. For example, the JVC GY-HM750 camcorder can accept voltages from 11V to 17V.
