Selecting the right battery capacity depends on several key factors:
For most consumer drones, batteries range from 1500mAh to 5000mAh. A general rule is: higher capacity means longer flight times but also adds more weight. For example, a typical 2500mAh 3S LiPo battery provides about 15-20 minutes of flight time for a medium-sized drone. Check your drone's manual for the recommended capacity, and consider keeping FAA guidelines in mind regarding maximum flight times and reserve power requirements.
