<<< Grins >>>
Some of us built our own Battery Cases/Boxes, some just have the cells bound together & sitting on "shelves", others use manufactured metal cases like "Seplos" offers or any number of others. The First TWO Options can really toss people for a loop, just the visual makes'em cringe, but for some, they think it's "cool".
Many now do offer assorted manufactured cases. Rack Mountables to Stackables to Roller Cabinet style. Some vendors are simply put, Ludicrous for their case kits, while others are not.
I built Plywood Boxes with Perspex clear tops, they look cool and are very neat BUT offputting to some (electrical inspector) who accepted it grudgingly... But thinking forward, I am redoing them all & adding another pack into my Bank and using these cases. (with a slight customization for my specs), shown below is similar to what I am bringing in.
View attachment 175060These are nowhere near the cost of "seplos" retail cost. Sorry, I am getting these from the Manufacturer, not an open vendor. BUT with careful searching they can be found.
Any inspector, prospective buyer, or interested visitor/guest will see the stack of these and not think overly much about issues, complications etc.
