Circuit Breaker vs Maxi Fuse

I have the circuit breaker on my second battery, to protect the truck. I had something shift, and a short circuit on the rear battery occurred. Fire in the back of my truck, i got lucky and put it out.

What im getting at is, either will work, one is a buy once and done, other you can tailor fuse to your needs.

secure and protect the battery.which i have taken the time to do since the incident.
