Stu, thank you for the reference to Jim Moe's article. From that article, which touches on all sorts of good things, I take away relevant to the current situation that:
(1) fuses should be rated at 150% of the charger capacity [which I think but will check will mean a 45 amp fuse for the XC3012];
(2) the fuses can be conveniently located in the battery box; and
(3) the AYBC code requires the fuses.
Conclusion: we will install fuses (or circuit breakers) in the battery compartment on the charger-to-battery cable runs.
