suitable metal battery box?

Hi,

I've been looking through the local Home Depot looking at metal "Job box"es used by contractors for containing the batteries we are making/made.

Am I looking up the wrong tree?

Anyone have an idea for a metal battery box?

I plan on storing my batteries in the back yard, along with the inverter.

Thanks,

Paul

Old servers. 2u-4u units could work. They are often in metal. There is someone here working with that.

On another thread they're talking about battery boxes, and thinking of using Hardie board which is a very fireproof material. I'm thinking, that if I'm hundred and thirty feet from the nearest habitable structure, a cedar box that is attractive in Blends in with the Landscaping is a way to go. Thanks Paul
