The importance of monitoring cycle count arises from the relationship between usage and battery capacity. Over time, batteries degrade due to chemical reactions that occur during charging and discharging. This degradation affects the battery’s ability to hold a charge. As the cycle count increases, the battery’s overall capacity diminishes, leading to shorter flight times and reduced performance.
In battery technology, the term “capacity” refers to the maximum amount of electric charge the battery can store. A higher cycle count typically correlates with reduced capacity. For instance, a new DJI Phantom battery may have a capacity of around 6000 mAh (milliampere-hours), but after numerous cycles, it might only provide 80% of that capacity or less.
Several factors contribute to battery degradation. High temperatures during flight, excessive discharge, and improper charging practices can accelerate the aging process. For example, frequently allowing the battery to discharge below 20% can lead to more immediate stress on the cells, increasing the cycle count faster than normal.
To illustrate, consider a scenario where a DJI Phantom battery has a cycle count of 150. With each additional cycle, the battery may start to lose about 20% of its total capacity. If this battery was regularly discharged improperly or exposed to extreme temperatures, users might notice a significant drop in performance even before reaching the recommended 300-cycle count limit for optimal usage. Thus, closely monitoring the cycle count enables users to replace the battery before it severely impacts drone performance.
