Why do Li-Ion cells have a Cut-Off voltage?

For example, a lithium-ion battery might have a cut-off voltage of around 3.0-3.3 volts per cell, while a lead-acid battery might have a cut-off voltage of around 1.75 volts per cell. It is important to monitor the cut-off voltage of a cell or battery to ensure that it is not discharged beyond its safe limits.

Low voltage cut-off: a false sense of security

Even a load with a low voltage cut-off cannot prevent this problem: the total battery voltage may very well be above the cut-off point, yet an individual cell may be over discharged. You may feel comfortable using a 10-cell LiFePO4 pack with a motor drive with a low-voltage cut-off of 25 V, a full 5 V above the 20 V minimum.
