Battery box

I built the wooden battery box today. It needs some minor fixes here and there but overall it's done. I used a piece of 1-1/2" PVC pipe screwed in and caulked around for the vent. The floor vent is going to end up half way covered up so I will see about adding some hose vents down through the floor where the bathroom shower & sink drain goes through. It will house two group 27 batteries with plenty of elbow room so getting them in and out will be easy. There is a lid (not pictured) that will be screwed down to seal it up.

I also changed two wires to a heavier gauge from the batteries to the 30A breaker and from the breaker to the fuse panel. The short red wire is actually smaller now for the larger black wire on the same terminal of the breaker so I will go back and change it. It's meant to feed everything 12V from the batteries, so it needs to be heavier gauge than 12. I think the larger black wire on the same terminal is 10g. It's some old wire I had laying around from when I had an extra battery hookup in the Ford conversion van I once had.

The 30A breaker may also be wired up backwards.. I gotta try to figure out what that wire is coming from the other side of the breaker is, It's pretty small gauge and seems to be spliced in or has something spliced to it. I haven't examined it closely enough to see yet.
