Fuse for pair 6v Batteries in series
Hello and thanks to all in advance! I read that one should have a fuse at the batteries just in case? What's the purpose of this installation? I want to protect the batteries especially after payi...

I think you said you were relocating your batteries? If it's a long run to the main fuse, then you're right, you should fuse it near the batteries too. It's all about the propensity for wire damage upstream of the fuse, so if the wires between the battery and main fuse (I'm sure your camper has one) can't realistically get damaged, rub thru the insulation, etc, then it is theoretically not needed at all.
In Roys case above, 130A seems like too big a fuse to me. Fuses should only be sized nominally larger than the max possible/intended amp draw at peak. Although if he has the charging circuit (I assume) wired with sufficient size wire for a 100A load then it'll handle 130A long enough without heating the wire enough to burn it up to pop the fuse.
Check out this site. Www.bcae1.com. It explains about anything you'd need to know about DC wiring. Particularly for car stereos, but the Principle is the same for your camper batteries.
