Abstract: A utility cart includes a stored energy device that can be in the form of a Lithium Ion battery pack. The battery pack can include a main power output useful to drive high voltage components as well as the electric motor for motive power. The battery pack can also include one or more auxiliary outputs useful to provide auxiliary power to various other components. The auxiliary outputs can be either low and/or high voltage outputs. An auxiliary DC/DC output can be used to step down high voltage of the Lithium ion battery pack to lower voltages. A motor controller supply can also be provided as an auxiliary output to provide some power to a motor controller.
