Review on 🔌 Bay Marine Supply MRBF Terminal Fuse Block Kit (Fuse Included) – Single Stud 5/16" (M8) Compact Marine Rated Battery Fuse 250A: Ensuring Reliable Power Protection for Marine Applications by Bashar Shaffer

The system I'm building will be installed in a location that just doesn't have a lot of room to place components. I used these fuse blocks in two places: screwed directly to the positive terminal of the lithium battery (for the main system fuse) and to the main system switch output terminal (for the high current branch circuit). I don't recommend connecting directly to the battery terminal unless you are using lithium batteries. Aside from the space constraints, I also use them because they are IP66 certified, so they can work in harsh environments. The only downside of these MRBF fuses is that replacement fuses are very expensive compared to MEGA/AMG fuses and especially AMI/MIDI fuses.
