I am using a Series 31 Battery and its 13" long 6 3/4" wide and needs at least 10" Height. I called summit but the guy didn't seem too sure. The Dimensions listed are for the exterior i believe. I was just curious if anyone was running this battery box and could tell me what the inside dimensions are. Any other boxes you guys may know of let me know. But i want something Very rugged. I Provided a link as well.
