What voltage does a lithium ion battery use?The standard lithium battery voltage ranges between 3.2V to 4.2V depending on chemistry. Most common lithium-ion batteries operate at 3.7V nominal voltage, while lithium iron phosphate (LiFePO4) batteries use 3.2V per cell.
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.
What is a safe voltage for a lithium ion battery?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 lowest range which is the minimum safe voltage for lithium-ion batteries is approximately 3.0V per cell.
