They really don't need to be in a box. I have mine in the front storage of my 5'er, braced so they don't slide around, and a piece of plywood on top to protect the terminals. Adds a nice shelf.What’s the best option for lithium battery storage? I’ve got a 364BHL and just installed two Dakota Lithium 100ah but they don’t fit in the factory battery tray. Looking for options. Thanks
