In the evolving landscape of unmanned aerial vehicles (UAVs), the partnership between DeltaQuad and Tulip Tech exemplifies how collaboration drives technological progress. DeltaQuad and Tulip Tech achieved a historic milestone in the European drone industry by powering the DeltaQuad Evo to fly for a record-breaking 8 hours and 55 seconds. This unprecedented endurance was fueled by innovative solid-state lithium-metal battery packs developed by Tulip Tech, setting a new benchmark for the longest fully electric VTOL UAV flight in Europe. Together, we have built a partnership rooted in innovation, reliability, and shared ambition.

Transforming UAV Performance

The DeltaQuad Evo

The DeltaQuad Evo continues to redefine the capabilities of vertical take-off and landing (VTOL) UAVs. This milestone flight places the Evo comfortably within Group 3 drone endurance capabilities, all while maintaining a lightweight Group 1 weight profile, a rare combination that expands operational flexibility. Despite challenging weather conditions, including rain and wind speeds up to 22 knots, the Evo completed its flight with significant battery reserve, showcasing remarkable operational robustness in real-world scenarios.

The Power Behind the Evo

Tulip Tech’s Solid-State Lithium-Metal Battery Packs 

At the heart of this achievement lies Tulip Tech’s pioneering battery technology. Our solid-state lithium-metal battery packs, with energy densities exceeding 450 Wh/kg, delivered stable and efficient power output throughout the flight, leaving ample capacity after landing. This next-generation battery technology is a game-changer. enabling longer, safer, and more capable UAV missions that extend operational reach without compromising reliability or safety. This flight is more than a record; it is a vivid demonstration of what deep-tech innovation can achieve when paired with real-world performance demands. By pushing the limits of energy density and endurance, Tulip Tech is powering the future of tactical drone operations

Looking Ahead

Building on this success, DeltaQuad and Tulip Tech will begin extensive testing of the Evo under varied weather, payloads, and navigation setups. The solution is planned for release in Q4 2025, continuing to push UAV performance boundaries.
