X4-1900H Hydrogen Fuel Cell Drone for Heavy Payloads

1. Product Overview

The X4‑1900H is an advanced hydrogen-powered drone engineered for heavy industrial operations. Equipped with a high-performance X9 propulsion system, this platform supports a maximum take-off weight of 52 kg while maintaining exceptional flight stability and redundancy. Its hybrid power system includes a 48 V / 3 kW hydrogen fuel cell and dual 6S 5300 mAh lithium batteries, enabling up to 2 hours of endurance under unloaded conditions.

The frame features a 1900 mm wheelbase, with foldable arms reducing its footprint from 1500 mm to 900 mm for easier transport. With a top speed of 18 m/s, climb rates up to 5 m/s, and cruise range up to 15 m/s, the drone is built for rapid-response deployment in power inspection, agriculture, surveillance, and logistics. A 20 km video link and centimeter-level RTK positioning ensure real-time, long-range operations with unmatched accuracy.

4. Customer FAQ (Pre-Sales)

Q: How does this drone maintain safety under full load?
A: The X9 propulsion system offers redundancy, ensuring continued flight even if one rotor fails. The hydrogen-electric hybrid architecture allows fallback to battery power, and automated flight controls handle emergency landing and return-home protocols. All systems undergo strict safety validation.

Q: Is hydrogen refueling complicated?
A: Not at all. Refueling typically takes just 3–5 minutes using the portable filling station we provide. We also support clients with hydrogen logistics and offer access to expanding refueling infrastructure.

Q: Can a non-professional operator fly this UAV?
A: Yes, though some training is advised. With automated takeoff/landing, RTH (Return to Home), and one-click mission execution, operation is streamlined. For industrial work, we provide setup tutorials and operational guidance.

Q: Does it really support 20 km HD transmission?
A: Yes, under ideal conditions (clear LOS, minimal interference). Our communication module uses robust anti-interference protocols to maintain reliable connectivity in diverse environments.

Q: What's the typical lifespan of the fuel cell?
A: Under standard usage, the hydrogen fuel cell can deliver between 500 and 1000 flight hours. We offer cost-effective maintenance plans and provide replacement cells at competitive pricing.
