In batteries, the cut-off (final) voltage is the prescribed lower-limit voltage at which discharge is considered complete. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved. The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When t.
The cutoff voltage for a lithium battery is 2.75V, which means it is not suitable to discharge any longer if the lithium Battery Voltage reaches this value. This may result in irreversible damage to the partial capacity of the lithium battery or even serious damage to the battery itself. The rated voltage of a single lithium battery is generally 3.7V.

Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
Different lithium chemistries have varying cut-off voltages based on their unique characteristics: Lithium-Ion (Li-ion): Generally has a cut-off voltage of around 2.5V to 3.0V. Lithium Iron Phosphate (LiFePO4): Typically set between 2.0V and 2.5V, allowing for deeper discharge without damage.

Besides, it is compatible with USB supplies and wall adapters. For best results in charging a 3.7 V Lithium-ion battery, apply a constant current of approximately 20 to 70 % of its capacity. You should do this until it reaches 4.2 V. Afterwards, charge the battery at a constant voltage until there is a 10% drop in the initial charge rate.
