Is draining a Li-Ion to 2.5 V harmful to a Li-ion cell?
$begingroup$ Yep -- for Li-Ion batteries there are three important protections: OCP (over-current protection), UVP (under-voltage protection) and OVP (over-voltage protection). OCP applies in both directions, charge and discharge, and the value at which it trips (especially charge) varies with temperature -- it''s a bad idea to charge a Li-Ion battery at a …
