At the battery end I was also planning to use a copper solderless lug screw clamp connector: SLU70, along with the oxide inhibitor gel they sell.
I'm not sure those connectors are good for stranded wire - especially if it's finely stranded. I think you need one with a plate that prevents the screw from screwing into the wire.
Here's a compression type connector:
The main issue with the above connector is ensuring it does not come loose - but your proposed connector has the same issue, along with others - like damaging the wire. Another possible issue with the quick cable compression connector is the wire size needs to be correct. You only get so much "squeeze" and a wire diameter that's too small won't work well. I don't know how to check that other than with trial and error.
Here's a solder type connector. There are two possible issue with these. One is having them get hot and the solder melts. I think this can be mitigated by putting the fuse directly on the battery - blue sea sells a battery post fuse. There's also some concern about vibration. I'm not sure how much vibration matters and what the mitigation strategies are.
If you know the exact length you need - you can get custom wires from genuinedealz.com for a reasonable price.
In any case, I suspect that any of the above would be better than the clamp.
