Just a thought on color I have the Obsidian Pro 4, also have 2 extra batteries. One is Obsidian the other white ( only thing available at Best Buy at the time plus on sale). Anyway the white battery in black body is easier to see, that gives me a good idea which is rear of The Quad, Seems to help on direction of Quad. Black or white both batteries are the same, So it is personal preference, just enjoy and have fun
