We report the creation of dual-species Bose-Einstein condensates (BECs) of
7Li and
133Cs. These BECs are formed in a bichromatic optical dipole trap created with 1550-nm and 780-nm laser beams. During the production process, an external magnetic field of 886~G is applied to adjust the scattering lengths to
aCs=123a0,
aLi=484a0, and
aLiCs=248a0. These scattering lengths allow for efficient evaporation and sympathetic cooling. The dual-species BECs are typically produced with
1.5×104 Cs atoms and
6.0×103 Li atoms. This quantum degenerate mixture of Li and Cs provides an ideal platform for exploring phenomena such as polarons and Efimov trimers, as well as for creating ground-state LiCs molecules.
