Why is it important to inspect lithium batteries before each flight?

Inspecting lithium batteries before each flight is crucial primarily because damaged batteries can self-ignite. Lithium batteries, particularly those used in sUAS (small Unmanned Aircraft Systems), have a known risk of catching fire or exploding if they are compromised, which can happen due to visible damage such as swelling, punctures, or corrosion. These failures can occur unpredictably, leading to catastrophic situations during flight.

Ensuring the integrity of the battery is key to both operational safety and the protection of the UAV, as well as people and property in the vicinity. A thorough inspection can help identify any issues before they lead to battery failure, thereby preventing serious accidents.

While other factors, such as energy efficiency, weight discrepancies, and compatibility with the UAV, are also important considerations for flight operations, they do not carry the same immediate risk implications related to safety as the potential for a damaged battery to self-ignite.
