An assembly for easily inserting, removing and carrying a motorcycle battery. In one embodiment, the alternative source comprises a five-gallon bottle of water and the mounting for the bottle includes a removable cover for preventing contamination of the system when the bottle is not in place. The relief valve regulates oil pressure within an oil path by discharging a portion of the hydraulic oil from the oil path. The first barrier material provides the edge seal while the second barrier disposed over the pixel provides protection from top down moisture diffusion. The filtering is selectable by a fuse option. The device of the invention has the advantages of constant current, simple driving circuit and low cost under the high-voltage high-power application.
