Abstract

A device and method of use directed to providing various voltages based on the voltage selection by the user for various applications. In one embodiment, the device is comprised of two or more 12 volt batteries coupled in a manner that allows the voltage output of the device to be modified by allowing each battery to change from in parallel to in series with a switching device. In another embodiment, the switching device may control all batteries, there may be more than one switching device whereby a switching device may control one or more batteries, or each battery may have its own switching device to determine which state the battery is in.
