Methods for charging 7S+ lithium-ion battery packs from DC
Discharge rate doesn''t affect the capacity either. It''s just that you reach the low-voltage cutoff point earlier due to resistive drop using high currents. If you add a CV phase to the discharge cycle, or lower the low-voltage cutoff below the specs (not recommended), you''ll get the same mAh out at 0.1C or 2C.
