I assume it has the molded plastic under the hood for 2 batteries like mine did? I cut out that divider piece in the middle and then the big battery goes in on its side on an angle, hood should close without any interference. I would measure and re-measure before you cut as i cut out more plastic than i needed because i thought i needed the space, i in fact did not. Just used a few pieces of tire tube for a buffer on the bottom to help cushion it and a new strap over the top, ready for action.
