In between batteries (unless regulations require) it is not necessary. Fusing is for wiring not so much equipment protection. The bms takes care of the battery as you said. There is a decent product that acts a a rapid disconnect and fusing, look up the mersen fuse disconnec t. There is quite a range of them for different amperages needed.
There are various fuses to consider, such as blade-style, ANL fuses, and standard 10x38 fuses. Blade-style fuses, common in automotive applications, aren't typically suitable for lithium battery systems. ANL fuses may also fall short in voltage specifications for these types of batteries.
For battery systems it is not advised to use standard glass fuses. They often lack the necessary interrupt current rating for a lithium battery bank, posing a significant risk. There are various fuses to consider, such as blade-style, ANL fuses, and standard 10x38 fuses.
MEGA fuses are perfect for loads and chargers as they come in a range of Ampere ratings from 60A to 500A, they are common and easy to source due to their use in vehicles and they are relatively cheap. They are not suitable for use as the main battery protection fuse with a LiFePO4 lithium battery however.
ANL fuses may also fall short in voltage specifications for these types of batteries. A better option is the standard 10x38 fuses for smaller battery systems. These come with ceramic tubes filled with auxiliary materials, providing the high interrupt current ratings necessary for lithium battery systems.

What size wiring as well?
