Battery short circuit protection?
I've been working on a solar system and 2000w inverter install. Lots of wiring. Lots of heavy duty cables (inverter to batteries). I've also got a battery monitor set up which uses heavy duty cabli...

for fusing a battery you need to consider two things
1) max draw that you want to allow (when the fuse will blow or breaker trip)
2) max circuit interupt the fuse/breaker can handle. you want a fuse that will blow at say 200A but will not sustain the 1000A or so the battery can supply via a continuous arc across the open fuse.
Fuses that can handle that type of load are usually larger than the typical fuse and sand filled to extinquish the arc. And some have fuseholder that can be mounted directly to battery terminals.
