FAQs 6

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 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 is lithium battery chemistry?

Lithium Battery Chemistry: Different lithium battery chemistries have distinct voltage characteristics. For instance, LiFePO4 batteries typically have a lower nominal voltage (around 3.2 volts per cell) than Li-ion batteries (about 3.6 to 3.7 volts per cell).

What happens if a lithium battery is mixed together?

If different capacities or old and new lithium batteries are mixed together, there may be leakage, zero voltage and other phenomena. This is due to the difference in capacity during the charging process. Some batteries are overcharged when charging, and some batteries are not fully charged.

Can lithium batteries with different voltages be grouped in series?

Do not let lithium batteries with different voltages in series. Due to the problem of consistency of lithium batteries, they are grouped in series under the same system (such as ternary or lithium iron), and they also need to be selected with the same voltage, internal resistance, and capacity.

Can a lithium battery be charged in parallel?

3.) If the battery charged in parallel does not have a lithium battery protection board, the charging voltage must be limited to 4.2V, and a 5V charger cannot be used. 4.) After the lithium batteries are connected in parallel, there will be a charging protection chip to charge and protect the lithium batteries.
