How do I choose a lithium-ion battery pack?

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 voltage does a lithium ion battery drop?

For example, a lithium-ion battery will drop from around 4.2V (fully charged) down to 3.7V, then further to 3.0V (cut-off voltage), after which the device will stop working. During Charging: When charging, the battery voltage increases. For lithium-ion batteries, the charging voltage typically starts around 4.2V per cell.

What happens if a lithium ion battery falls below 2.5V?

When the voltage of a lithium-ion battery falls below 2.5V, the electrochemical stability of the cell is compromised. This leads to excessive lithium-ion extraction from the cathode and can cause the copper in the anode to dissolve.
