What is the minimum acceptable battery voltage to connect external power to avoid damage?

The minimum acceptable battery voltage to connect external power is crucial for ensuring the safe and efficient operation of the system. At 22.0 volts, this voltage level is typically the threshold required to prevent potential damage when external power is applied. Connecting external power at lower voltages can cause irregularities in power distribution, or stress the electrical components, which could lead to damage or failure of the system.

Maintaining this minimum voltage is essential because it ensures that the system's batteries are sufficiently charged to handle the additional load from the external power source. This helps in protecting against power surges or electrical malfunctions that could occur if the battery voltage is too low. Proper voltage levels contribute to overall system stability and longevity, making it vital to adhere to these specifications.
