Safety Features:

 

Over - charge Protection

 

18650 Li - ion battery packs are equipped with over - charge protection circuits. These circuits monitor the battery's voltage during the charging process. When the voltage reaches a pre - determined upper limit (usually around 4.2V per cell), the protection circuit cuts off the charging current. This prevents the battery from being over - charged, which could lead to a variety of problems. For example, over - charging can cause the battery's internal components to degrade more rapidly, reducing its overall lifespan. In more severe cases, it can lead to the formation of lithium dendrites, which can cause short - circuits and potentially lead to a fire or explosion.

 

Over - discharge Protection

 

The battery packs also have over - discharge protection. As the battery is used and its voltage drops, the over - discharge protection mechanism comes into play. When the voltage reaches a lower limit (around 2.5V - 3.0V per cell, depending on the specific battery design), the circuit disconnects the battery from the load to prevent further discharge. Over - discharging can cause irreversible damage to the battery's electrodes and electrolyte. It can also lead to a loss of battery capacity and an increase in internal resistance, which affects the battery's performance and long - term usability.
