The battery box does provide the function of preventing terminal shorting, but so do many battery compartments lids AND terminal boots. I'm not opposed to a belt and braces approach but when only one it needed there is no reason to sacrifice space.
As for ratchet straps, if its for batteries inside the boat I say let the cheap ones rust. 10 year from now I'll buy new cheap ones.
