6. Controlling depth of discharge
Instead of merely cutting off loads when a low-voltage threshold has been reached, it takes into account the amount of current being drawn from the battery. When the current being drawn is high, the shut-down voltage might be 10V, for example; whereas if the current being drawn is a small one, the shut-down might be 11.5V.

Understanding Charge-Discharge Curves of Li-ion Cells
The CC-CV method starts with constant charging while the battery pack''s voltage rises. When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current. The charging current keeps coming down until it reaches below 0.05C. The battery reaches full charge voltage some …
