Attaching a fuse to a new set of batteries?
Due to various craziness in life, I let the batteries on my rig expire, so the only purpose they have is a core charge refund. This time around, I'm getting two 12 volt jars, using 36" 0 gauge cables...

A short would presumably be a single shorted cell, not a dead short across a single 12V battery.
Well ... current flow rate is all about the potential (voltage difference) driving it and the capacity of the potential source to supply the rate.
I worry about one battery going bad and having one shorted cell such that it becomes downgraded to only a 10 volt battery. Hence (with, say, two originally 12 volt batteries in parallel) you would then have a 12 volt good battery with a capacity for supplying maybe 1000+ instantaneous amps across the 2 volt potential difference created by the 10 volt bad battery "load" in parallel with it.
I wonder how much heat and/or gas pressue a 1000+ amp current flow driven by 2 volts can create?
If my fears are justified, I guess it might be a good idea to fuse between paralleled RV batteries ... just in case.
