Does anyone know of any of the more affordable trolling motor LiFePO4 batteries that can be laid on their sides? My old lead acid deep cycle is finally giving up on me and if I am getting a new battery I want a lithium. The boat is a 1648 Alumacraft flatbottom with a factory 4' front deck with a small cubby under it, which I where I want the battery to go. I need a 12v 100ah one and the issue is, is that all of those are too tall to fit in there, however, they will work if they can lay on their long side. The one below is the one "affordable" battery I have found so far that supports side installation. Just wondering if anyone knew of any others that had the same specs and are in the ballpark from a price point.
