I've been wanting to buy/use a marine battery as a 1vdc

Thing is I don't know if there exists a "box" that will
contain he battery yet allow USB and 12vdc "ports" to
be obtained from it?

Bottom line...does there exist a "box" that will hold a
heavy battery such as this yet maybe have internal
connections for USB charging ports and still allow hook
up of 12vdc car "trouble" lights for home lighting?

I've never heard of such a box, but if you can't find one
you could make one yourself fairly easily using:

An ordinary battery box
A couple of cigarette lighter outlets from auto parts store
A 5V voltage regulator, plus maybe a small heat sink from Radio Shack
A USB extension cable

And even if such a box does exist, I bet the above might
be a lot cheaper.
