The good thing is that even though my battery tray that is under my steps (shown where the blue box is in the picture below), I have a storage compartment close to it (red box) that I could eventually add support to add a couple more batteries. Perhaps something like AGM.
Currently there is a small tv hanging on the wall of that compartment. Would there be any issue with some batteries at the bottom with the tv in there? I assume AGM since they won't need to be vented.
