just to follow up on Pablo's reply, you might want to take a look at star/test_suite/cool_brown_dwarf.

it runs a 0.05 Msun model and gives depletion histories like these:

try modifying the inlist to increase the mass to get significant Li burning.  e.g., here's for 0.15 Msun:

you can compare these to Fig 17 in the 1st instrument paper:
