Why should lithium batteries be inspected for damage prior to each flight?

Inspecting lithium batteries for damage prior to each flight is essential primarily to prevent potential self-ignition. Lithium batteries can pose significant safety risks if they are damaged, as physical damage can lead to internal shorts, overheating, or even fires. The chemical composition of lithium batteries can make them volatile under certain conditions, particularly if their integrity has been compromised.

By conducting a thorough inspection, operators can identify any signs of swelling, punctures, or other types of damage that could lead to malfunction. This pre-flight check is a critical safety measure to ensure that the batteries are in good condition and can safely power the unmanned vehicle during operation, thereby minimizing the risk of incident and ensuring the overall safety of both the aircraft and the environment in which it operates.

The focus on preventing self-ignition highlights the importance of diligence when handling batteries, especially in aviation contexts where safety is paramount.
