If I did put batteries in my house, I'd want them mounted on wheels so if they overheat I can push them out before things get exciting. Those do exist, and apart from storing juice for your house they can also take you places...
There is no way you could get close enough to a battery bank this size to push them once they started to catch on fire and not die. You might as well be trying to put out a kiddy pool of gasoline with your hands.
