Looks really good. One comment though. I don't know exactly what type of gas storage or venting lines you have set up there but it looks like that type of gas container was designed for open air use. You need to make sure gas vapors can't accumalate in that compartment, especially since the batteries are stored there. Not trying to diss your project as the work is awesome but I spent alot of time doing offshore fishing and boating etc and I KNOW that safety has to be a primary design consideration.
