How do I know when the batteries are fully charged?

When you put a battery in the charge indicator will change to white, once it is completely charged, it will go back to the same purple color that it was with no battery in the slot.

Will this charge 21700s?

idk it says 20700 look in description

Can this charge batteries of different chemistries?

If you mean diffent milli amper hours. Yes you can. I do not recommend any thing over 18650's because the e fest is designed for that mah.
