Drone Battery Performance

Impact on Flight Time

The battery you choose directly affects your drone’s flight duration. Soft-pack lithium polymer (LiPo) batteries provide a lightweight design with high energy density, enabling longer flight times without adding excessive weight. However, if the battery is too heavy, it will reduce flight time because the drone must exert more effort to stay airborne.

Over time, all batteries gradually lose capacity, resulting in shorter flights and the possibility of overheating. Swelling, leaks, or other physical damage are clear signs that the battery is no longer safe to use and should be replaced immediately to avoid risk.

Soft-pack LiPo batteries typically support hundreds of charge cycles, depending on usage and care. Proper battery maintenance and using high-quality batteries help ensure optimal flight performance and safety.
