The AMoRE collaboration searches for neutrinoless double beta decay of Mo-100 using molybdate scintillating crystals via low temperature thermal calorimetric detection. The early phases of the experiment, AMoREpilot and AMoRE-I, have demonstrated competitive discovery potential. Presently, the AMoRE-II experiment, featuring a large detector array with about 90 kg of Mo-100 isotope, is under construction. This paper discusses the baseline design and characterization of the lithium molybdate cryogenic calorimeters to be used in the AMoRE-II detector modules. The results from prototype setups that incorporate new housing structures and two different crystal masses (316 g and 517-521 g), operated at 10 mK temperature, show energy resolutions (FWHM) of 7.55-8.82 keV at the 2.615 MeV Tl-208 gamma line and effective light detection of 0.79-0.96 keV/MeV. The simultaneous heat and light detection enables clear separation of alpha particles with a discrimination power of 12.37-19.50 at the energy region around Li-6(n, alpha)H-3 with Q-value = 4.785 MeV. Promising detector performances were demonstrated at temperatures as high as 30 mK, which relaxes the temperature constraints for operating the large AMoRE-II array.
