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.
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.
Operating below recommended voltages may cause reduced performance or prevent devices from functioning; prolonged low-voltage operation could damage cells over time. Lithium-ion batteries power modern devices. Voltage drives current, while amperage measures flow, both crucial for performance and efficiency.

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.
Lithium batteries have different voltage levels primarily due to variations in chemical composition and construction. For instance, lithium-ion (Li-ion) and lithium-polymer (Li-Po) cells generally have a nominal voltage of around 3.6 to 3.7 volts, while lithium iron phosphate (LiFePO4) batteries operate at around 3.2 volts.
