If your trying to build an external battery box that will also have the fish finder mounted to the lid, so as to be portable. Your going to need a much larger box than a 1120 because it seems as though you would wand to contain the 20 feet of transducer cable most systems use. If you use a larger box it could hold the battery and all the extra cable inside. Mount the fish finder and attachment to a transducer arm to the outside of the box lid. I don't think you would want all that cable wound up and hanging loose outside the box.
