    Works well ( I haven’t tripped it so I can’t guarantee quality of fuse itself).

    Just make sure to place washers between fuse and wire otherwise you moght melt the plastic casing.

    Battery bank protection. One on each battery before connecting to a buzz bar. Great protection in case of thermal run-away or excessive load on individual batteries.

    5.0 out of 5 stars Used for side post optima red top. Great product. 1964 impala SS
    Reviewed in the United States on October 20, 2024
    Verified Purchase
    I used this for when I did a big 3 wiring upgrade on my 1964 impala SS. I ran a 1/0 copper spartan welding wire (great wire, available on amazon) from my 200 amp 1 wire alternator. I wanted to keep the top post open for all my other wiring (air bag suspension system compressors vlair 485's , big stereo 3000+ watts of amps, and a battery isolator running to another optima yellow top in the trunk for dual charging, SAE 3.3ft 10gauge fused connector hidden in bumped to plug a trickle charger in without opening the hood, etc.) So this runs dedicated to the side post of an optima red top 75/25 battery. I put a 200amp fuse on it and keep an extra in my car tool bag, although I haven't had any issues.

    Only problem is it sticks up a bit. Had to cut the bolt down about a quarter of an inch to make it clear the steps in my motorhome. Other than that it works fine.

    2.0 out of 5 stars HOT, Don't use on Lithium batteries.
    Reviewed in the United States on July 14, 2025
    Verified Purchase
    Beware, I bought a 200 amp version of this. After running 140 amps for 30 minutes this thing got so hot the cover melted and it melted the terminal loose inside my new lithium battery. I'm not happy! I hope my battery doesn't fail prematurely now because of this thing. Do not use these on lithium batteries!
