When selecting a lithium-ion battery pack, understanding its voltage characteristics is crucial for ensuring optimal performance and longevity. Three key voltage terms define a battery's operation: Nominal Voltage, Charged Voltage, and Cut-Off Voltage.

What should you know about lithium ion batteries?

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.

How many volts is a lithium ion battery?

Here’s a simple breakdown of fully charged voltages by lithium-ion type: Devices rely on voltage to estimate battery level. Overcharging can trigger thermal runaway—a dangerous chemical reaction. Fully charging to 4.2V gives you max run-time, but stopping around 4.1V can extend battery life.
