tiger dude may I make two suggestions. The first would be to put an inline fuseon your battery to all power on your box. This will keep your battery from smoking and going up in flames due to an inadvertent short. This next suggestion is that you put a main cutoff swich for the battery with a switch cover over it. This last suggestion is low priority but the first one is a really good idea since you can not get into a battery compartment very fast.
