Features of FPV batteries:
1. High performance requirements: FPV drones are mainly used for racing, aerobatic flights or first-person experience, so FPV batteries emphasize high discharge rates (higher C numbers) and can provide high-intensity power output in a short time.
2. Lightweight and miniaturization: In pursuit of extreme speed and flexibility, FPV batteries tend to be lighter and smaller so that they can be installed in compact FPV models and reduce the overall mass of the drone.
3. Quick replacement design: Given that FPV competitions or performances may require rapid battery replacement to continue flying, FPV batteries are usually designed with quick disassembly and assembly interfaces, such as XT60, for quick on-site operation.
4. Impact resistance: Considering the collisions that FPV drones may encounter during high-speed flight and complex environments, their batteries usually have better physical protection designs.

Features of UAV batteries:
1. Long endurance: UAVs, especially drones used for commercial or industrial purposes such as surveying, agricultural spraying, and inspection, pay more attention to endurance, so their batteries usually have a larger capacity (mAh) to support longer flight operations.
2. Stability and safety: Commercial and industrial UAV operations require high stability and safety, and their battery design will pay more attention to the precise control of the battery management system (BMS) to prevent overheating, overcharging/discharging, and ensure long-term reliable operation.
3. Modularity and maintainability: For large UAVs, batteries may be designed to be modular for easy maintenance, replacement, and balanced charging, and may also need to comply with specific safety standards and certifications.
4. Environmental adaptability: UAVs may operate in extreme temperatures, humidity, or complex weather conditions, so the battery needs to have good environmental adaptability and a wider operating temperature range.

In general, the difference between FPV batteries and UAV batteries is mainly reflected in the design goals: FPV batteries focus on high performance and fast response, while UAV batteries focus more on endurance, stability, and adaptability to complex operating environments.
