The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
Lithium-ion batteries function within a certain range at which their voltage operates optimally and safely. The highest range where the fully charged voltage of a lithium-ion battery is approximately 4.2V per cell.

The voltage of a lithium-ion battery system always fluctuates during charging or discharging. If you see the voltage during charge or discharge cycles, you will notice that the voltage remains constant initially and then varies over time. In the discharge cycle, initially, the voltage will be 4.2V.
Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries. The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases.
For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle. The average nominal voltage also means a balance between energy capacity and performance. Additionally, the voltage of lithium-ion battery systems may differ slightly due to variations in the specific chemistry.
