Selecting the right battery capacity depends on several key factors:
For most consumer drones, batteries range from 2000mAh to 5000mAh. A general rule is that larger capacity provides longer flight times but adds weight. For example, a typical 3500mAh LiPo battery gives about 20-25 minutes of flight time for a mid-sized drone. According to IEEE Spectrum, newer lithium-ion technologies are improving energy density, potentially offering up to 40% longer flight times.
