Drone exam · UAS flight performance

Two batteries both indicate 100 percent charge, but one has many cycles and noticeably shorter flights. What does the display fail to show?

Answer

A full charge does not mean the battery has retained its original usable capacity or power capability. Review health indicators, history, cell balance, and manufacturer criteria.

Explanation

State of charge describes how full the battery is relative to its current capacity. State of health describes how much capability remains compared with a healthy pack.
