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.

Claims

1. A variable voltage system comprising:

a main battery;

at least two auxiliary batteries electrically coupled to each other and the main battery whereby the auxiliary batteries may be coupled in parallel or in series depending on the voltage output desired from the variable voltage system;

and at least one switch to control each auxiliary battery'"'"'s in parallel or in series coupling state to achieve the voltage output desired from the variable voltage system.

2. A variable voltage system according to claim 1, wherein said auxiliary batteries are 12 volt batteries.

3. A variable voltage system according to claim 1, wherein said auxiliary batteries are 18 volt batteries.
