I know the feeling of having parts just sitting on the floor waiting for more parts or money to finish a project. Items get misplaced, warranties expire, I forget why the heck I bought that thing, what is that thing, I forgot. I've had my turbo setup sitting in a box for over a year. I've been gathering everything I'll need for the install. Nothing like getting in the middle of a build only to discover you need one more thing that you can't afford. The only thing that I do on the battery relocation is run a ground wire all the way to the engine. I've had intermittent problems in the past with grounding thru the chassis. Most people have no problems, but when you do they can be really bizarre.
