Testing the battery life of an 18-inch X4 FPV drone under a demanding 10KG load reveals impressive endurance for heavy lift tasks. We configured this drone with high-performance components to simulate real-world scenarios in transport or rescue operations. The setup ensures reliability, and the results highlight its potential for extended flights in custom FPV drone applications.
Drone Configuration Details
We equipped the drone with an F722 12S flight control running BF firmware for precise handling. The electronic speed control features a 12S 100A AM32 unit, paired with robust 6218 200kv motors. For video transmission, we integrated a 5.8G 5W photo caption system, and the receiver uses an ELRS 915MHz module. The propellers consist of DBone1980 four-blade folding blades, which provide efficient thrust. Power comes from a 12S 40A 10C 5.3kg semi-solid battery with a QS-8 plug. The empty weight stands at 3.75kg, while the full takeoff weight reaches 19kg, incorporating the heavy payload.
In addition, this configuration optimizes the drone for stability during loaded flights, making it suitable for agriculture or transport FPV drone uses.
Test Setup and Conditions
We initiated the test with the drone hovering at 51% throttle during takeoff. The flight continued until the battery voltage dropped to 33.6V, which marks the minimum discharge cut-off point. Throughout the session, the drone maintained consistent performance without issues.
Furthermore, we monitored key parameters like hover throttle and overall flight time to ensure accurate data collection.
Impressive Test Results
The drone achieved a flight time of 30 minutes and 12 seconds, covering an estimated distance of 30 kilometers. This endurance demonstrates the efficiency of the power system under heavy load conditions.
As a result, these findings confirm the drone’s capability for prolonged operations, ideal for heavy lift FPV drone scenarios.
Real Photos of Weight Parameters
We captured images showing the full takeoff weight of the entire machine, no-load weight, battery weight, and load capacity to verify the setup visually.
In conclusion, this battery life test underscores the advantages of custom FPV drone specs for demanding applications. Operators can rely on such configurations for enhanced flight duration and reliability in 2025 heavy payload tasks.
