Any thoughts on the importance of the venting on a small battery? It's an 18AH battery.

Also, I came across this video the other day and I thought it was interesting.
These guys would be a place to start looking for enclosures for in your car. https://store.solutionsdirectonline.com/storefront.aspx

What dimensions do you need? I may have used ones that I would sell cheap.

The video is similar to what I want to do with the supercaps in my solar usb charging setup. His solar controller makes the supercap pack very limited, and he acknowledges that in a different video. If you size the supercap pack to accommodate the VoC (Voltage, Open Circuit) of the solar panel (will be ~17-18VDC on a 12VDC panel), then you can eliminate the solar controller (less cost, less current draw), and it starts charging as soon as sun hits the panel. The use of a buck/boost DC-DC converter allows one to extract a lot more of the energy stored in super caps because it allows you to use 3VDC to 20+VDC out of the pack.
