Full Charge Voltage and Cut-off Voltage of 24V Lithium-Ion Battery

The full charge voltage and cut-off voltage of a 24V lithium-ion battery are critical factors that affect the battery's lifespan and performance. The typical values for a 24V lithium-ion battery are as follows:

1. Full Charge Voltage
   25.2V: The full charge voltage for a 24V lithium-ion battery is 25.2V in a system composed of 6 cells, each charged to 4.2V. Since the maximum voltage of each cell is 4.2V, the total voltage when 6 cells are connected in series is 25.2V.

2. Cut-off Voltage
   21.0V: The cut-off voltage is the voltage at which the battery should no longer be discharged to prevent damage. For a 24V lithium-ion battery, this is typically set at 21.0V. This voltage protects the battery from excessive discharge and helps extend its lifespan.

Summary:

• Full Charge Voltage: 25.2V (4.2V × 6 cells)

• Cut-off Voltage: 21.0V (3.0V × 6 cells)

To maximize battery life, it is important to adhere to this voltage range.
