A battery pack assembly on the chassis, includes an AC to DC converter and plurality of batteries wired to a battery charger within a housing. The batteries collectively may have an output voltage of 30 to 36 VDC when fully charged. At least one input connector on the housing is wired to the AC to DC converter for charging the batteries. The battery pack assembly replaces and is used instead of a camera-equipment-generator. ## Claims ### Claim 1 A vehicle for carrying a camera crane, comprising: a chassis; a plurality of wheels rotatably attached to the chassis; a surface on the chassis for supporting a camera crane; and a battery pack assembly on the chassis, including an AC to DC converter and a plurality of batteries wired to a battery charger within a housing, the batteries wired to one or more output connectors and collectively having an output voltage of 30 to 36 VDC when fully charged, and at least one input connector on the housing wired to the AC to DC converter for charging the batteries, the battery pack wired so that wall current provided to the at least one input connector is converted to 30 to 36 VDC and is provided to the output connectors for powering camera equipment, and the batteries automatically disconnected from the output connectors via one or more relays when wall current is provided to the at least one input connector; and the vehicle having no camera-equipment-generator. ### Claim 2 (depends on 1) The vehicle of claim 1 with the battery pack assembly having six batteries, with each battery wired to a separate battery charger in the housing. ### Claim 3 (depends on 1) The vehicle of claim 1 with the battery pack assembly having a second output voltage of 12 VDC when fully charged. ### Claim 4 A camera crane, comprising: a chassis; a plurality of wheels rotatably attached to the chassis; a column pivotally supported on the chassis; a crane arm pivotally supported on the column; a battery pack assembly on the chassis, the battery pack including an AC to DC converter and plurality of batteries wired to a battery charger within a housing, the batteries wired to one or more output connectors and collectively having an output voltage of 30 to 36 VDC when fully charged, and at least one an input connector on the housing wired to the AC to DC converter for charging the batteries, the battery pack wired so that wall current provided to the at least one input connector is converted to 30 to 36 VDC and is provided to the output connectors for powering camera equipment, and the batteries automatically disconnected from the output connectors via one or more relays when wall current is provided to the at least one input connector; the camera crane having no camera-equipment-generator, with all electrical power used by the camera crane provided at least indirectly from the battery pack assembly; and the battery pack assembly provided as an accessory, the battery pack assembly supported on a surface of the chassis, and the battery pack assembly removable from the chassis. ### Claim 5 (depends on 4) The camera crane of claim 4 with the battery pack assembly having six batteries, with each battery wired to a separate battery charger. ### Claim 6 (depends on 4) The camera crane of claim 4 with the battery pack assembly having a second output voltage of 12 VDC when fully charged. ### Claim 7 (depends on 4) The camera crane of claim 4 with the housing having a front panel including a pair of LED indicators associated with each battery, and wherein all of the input connectors and output connectors are on the front panel. ### Claim 8 (depends on 4) The camera crane of claim 4 with the battery pack assembly having a length of 45 to 90 cm, a width of 38 to 76 cm, and a height of 38 to 76 cm, further including a left handle on a left side of the housing and a right handle on a right side of the housing, for lifting and carrying the battery pack assembly. ### Claim 9 (depends on 1) The camera crane of claim 1 further including a diesel or gasoline engine on the chassis. ### Claim 10 (depends on 1) The camera crane of claim 1 further including a diesel or gasoline engine on the chassis driving an alternator. ### Claim 11 Camera crane equipment, comprising: a chassis; a plurality of wheels rotatably attached to the chassis; a diesel or gasoline engine on the chassis; a battery pack assembly on the chassis, the battery pack including an AC to DC converter and plurality of batteries wired to a battery charger within a housing, the batteries wired to one or more output connectors and collectively having an output voltage of 30 to 36 VDC when fully charged, and at least one an input connector on the housing wired to the AC to DC converter for charging the batteries, the battery pack wired so that wall current provided to the at least one input connector is converted to 30 to 36 VDC and is provided to the output connectors for powering camera equipment, and the batteries automatically disconnected from the output connectors via one or more relays when wall current is provided to the at least one input connector; the camera crane having no camera-equipment-generator, with all electrical power used by the camera crane provided at least indirectly from the battery pack assembly; and the battery pack assembly provided as an accessory, the battery pack assembly supported on a surface of the chassis, and the battery pack assembly removable from the chassis.
