One small point: A lithium battery doesn't need to be vented so it doesn't need to be in a battery box. I ended up putting my battery + SmartShunt into a plastic file folder box.Slackers said:FWIW, Our 100 Ah Lithium was larger and required a Group 27 sized box. We were able to fit in it in the front tub by angling it. To do that I screwed some deck balusters along the inside rails of the factory tray. Then I screwed the Group 27 box onto the balusters. It takes some finesse to get the battery in and out of the box, but it works. The strap goes around the existing tray and battery box to keep everything snug.
