You are not really into reading, either, it seems. Or into the
electronics. Or into physics.

You seem to understand that charging li-ion from li-ion produces too
much heat. (And yes, it does, DC-DC convertors are not 100%
effective). Converting energy into heat is not a good idea.

If you need numbers or references to understand basic physics, you'll
need to google it yourself, I'm afraid.
