I have this VSR battery idolater, which states it has 'surge protection.' Do I still need to add fuses on either side of it?

Do your research, since I am
Not familiar with your components.
You could get a kit with the cable and terminals included if you don't want to get them crimped or do them yourself.
However, I like this style isolator better where the alternator output goes to one pole and each of the other poles go to the batteries. This way it truly isolates them vs the other which is more of a charging relay and basically connects the batteries in parallel for the purpose of charging because it requires bridging from the battery terminal itself.
