Jay, great questions. One of the few good things about the OutBack Skybox (I think it was that one) was the lifting holes on the upper back corners so that a bar or pipe could be run through making it much easier for a lift into place. Maybe for the 300 lb batteries lifting eyes on all four top corners so that 2 bars across the front and back could be used by 4 people to lift would be good. Of course a mechanical lift will also do the job. I've always thought that a battery that sits on the floor would be preferable unless subject to flooding. I've used different cable sizes and lengths to the extreme on my own system, and there is a slight difference in charge between batteries but it never gets too far out of balance. I do have one battery that gets slightly more cycling, but that is actually what I prefer in this instance. Remember the Aquion battery with the #12 cables and Amphenol PV connectors?
