  • (a) power source;

    (b) a voltage booster circuit in circuit communication with the power source, wherein the voltage booster circuit comprises a voltage converter, wherein said voltage converter comprises an input and an output and wherein the output is configured to provide a lesser voltage than the input;

    (c) a control circuit in circuit communication with the power source and voltage booster circuit, the control circuit comprising;

    a drive circuit in circuit communication with at least one motor; and

    (d) a switch in circuit communication with the power source, voltage booster circuit, and control circuit, the switch comprising a first state for connecting the power source to the control circuit and a second state for connecting the voltage booster circuit to the control circuit;

    (e) wherein the power source comprises a positive terminal having a voltage and a negative terminal and wherein the voltage converter output comprises a positive terminal and a negative terminal and wherein the voltage converter'"'"'s negative terminal comprises a voltage approximately equal to the voltage of the positive terminal of the power source.
