Abstract: A jockey wheel includes at least one ground engaging wheel; a mount for mounting the jockey wheel to a frame of a trailed vehicle; a jockey wheel post carrier for carrying a jockey wheel post; a coarse height adjuster for coarsely adjusting the height of the jockey wheel post, wherein the coarse height adjuster includes a locking selector for selecting a jockey wheel post height, the locking selector being biased into a locking position.

Abstract: A portable battery box is described. The portable battery box is suitable for charging and housing a battery and comprises: a housing having a lid, a battery removably disposed within the housing, an inverter, a computer processing system, and a display screen. The computer processing system is configured to be powered by the battery and used for receiving measured charge parameters of the battery and estimating other battery parameters.

Abstract: A portable battery box is described. The portable battery box is suitable for charging and housing a battery and comprises: a charging apparatus for charging a battery; a hollow lid shell and a hollow base shell for housing a rechargeable battery, the base hollow shell including a base wall, a top wall and at least one side wall extending between the base and top walls; and at least one handle disposed in a respective one of the side walls of the hollow base shell.

Abstract: A rolled terminal (50) for an electrical connector has a first portion (58) formed of a rolled sheet defining a bore for receiving an electrical wire, and a first aperture (62) in the wall of the first portion (58) for receiving a screw for clamping the wire between the screw and the wall of the first portion. Also included is a plug attached by cable to a towed vehicle, the plug associated with a magnet to enable it to be secured to the towed vehicle when the plug is not in use.

Abstract: The invention provides a battery box including a body (1) for housing a lead acid battery (2), the body having a base (3) and sides (4) extending from the base to define an open top (5). A lid (6) is applicable to the body to close the top. In use, the lid has at least one generally vertically oriented side (7). Each one of a plurality of relatively water sensitive electrical components is electrically connectable to the battery and housed substantially within the lid. The electrical components each have a user interface located on the vertically oriented side (7) thereby to inhibit damage to the electrical component as a result of water ingress.
