Modern FPV drones and unmanned aerial vehicles require stable and reliable power, as battery quality directly affects flight time, electronic system stability, and overall mission effectiveness.

Defense Technologies of Ukraine specializes in the production of batteries for FPV drones and various types of UAVs. We use high-quality components, proven cells, and modern assembly methods.

Batteries for FPV Drones and UAVs

Li-ion batteries for drones are designed to handle high loads, deliver stable current, and support long autonomous operation. These batteries are used in FPV drones, reconnaissance UAVs, specialized unmanned systems, and other aerial platforms.

During production, special attention is paid to:

• stable power delivery
• reliable performance under load
• high-quality internal assembly
• operational safety
• long service life of battery cells

Our batteries help reduce voltage sag during flight and ensure predictable drone performance even in demanding conditions.

Advantages of OTU Drone Batteries

OTU batteries for FPV drones and UAVs offer an optimal balance between power, weight, and endurance. Battery configurations are tailored to different tasks and types of unmanned systems.

Key advantages include:
