What Size/Type Fuse?

I'll be installing an additional Lithionics 12V 130Ah lithium battery in an RV. The battery specifications indicate that the max discharge current is 100A. So, does that mean I should install a 100 amp fuse? Something less to protect the battery? Something more because it has an internal BMS already, and I should just worry about melted parts?
The wiring diagram indicates a 200 amp fuse in one of the circuits, but its difficult to tell if that is for one or both of the other two batteries.
I'm I've been told to not worry about another fuse...just tap into the proper positive and negative bus bars. I've also been told to fuse the new battery, and that the original two have their own fuses. Safety would be to fuse the cable. Ease of install would be to not fuse.
I know I need a non-delay fuse. What else should I consider?
FYI: RV is a 2021 Winnebago Revel with two original Xantrex/Lithionics lithium batteries.
