Claim 1:
2. A hydraulic system comprising:
a machine with at least two axes of operation;
at least two directional valves, wherein each directional valve is operatively connected to an axis of operation;
a direct current (DC) hydraulic pump operatively connected to the directional valves;
a handheld controller comprising at least two bi-directional joysticks;
a battery with a battery output; and
a command center in electrical communication with the hydraulic pump, the handheld controller, and the battery;
wherein the handheld controller communicates with the command center to operate the directional valves and adjust the battery output to the hydraulic pump,
wherein movement of a joystick about a single axis corresponds to the operation of one directional valve and effects a variation in the battery output, and
wherein the battery output provided to the pump is within a predetermined range and is affected by at least one of movement of a first of the joysticks in a first direction; movement of the first joystick in a second direction, the second direction being orthogonal to the first direction; and movement of the first joystick in a third direction, the third direction being between the first direction and the second direction.
