Sorry a bit slow on this, I have a 2016 30' Flying Cloud. I just put in storage until next weekend, so I don't have the dimensions. It was the factory box that originally had 2 Insterstate SRM-24s in it, I can measure it when I get it back, but it was a straight switchout without any changes except I put some flextape over of the holes in the bottom to reduce dust.
I saw the picture of the Lion Energy batteries in the the battery box. What AS do you have? And what is the size of the box?
