Tattu UHV Batteries Power Hercules UAV for Aerial Survey Missions

Professional aerial sensing applications require UAVs to carry advanced equipment while maintaining sufficient flight endurance. For heavy-lift platforms, battery energy density and discharge performance play an important role in meeting demanding mission requirements.

In Nevada, USA, a Hercules UAV equipped with the HySpex VS-620 hyperspectral imaging system completed a 30-minute flight powered by four Tattu 41,000mAh 6S Ultra High Voltage (UHV) batteries.

Configured in a two-parallel, two-series arrangement (2P2S), the battery system supported a 12kg payload. The aircraft landed with more than 30% battery capacity remaining, while throttle stayed below 60% throughout the flight.

Project Challenges

Sustaining Flight with a Heavy Payload

The Hercules UAV was tasked with carrying the HySpex VS-620 hyperspectral imaging system, bringing the total payload to 12kg. This placed considerable demands on the aircraft's power system, which needed to support sustained flight while carrying professional-grade sensing equipment.

Meeting Flight Endurance Requirements

Aerial sensing missions require sufficient time in the air to collect data effectively. Achieving a 30-minute flight while carrying a 12kg payload was a key requirement for this operation.

Tattu Battery Solution

To meet the Hercules UAV's power requirements, the platform used four Tattu 41,000mAh 6S Ultra High Voltage batteries in a two-parallel, two-series configuration (2P2S).

Tattu UHV batteries feature higher energy density and a higher discharge voltage platform than conventional batteries, making them well suited to demanding UAV applications where battery weight, available energy, and sustained power output are important.

Higher Energy Density for Greater Energy Capacity

Compared with conventional batteries, Tattu UHV batteries offer higher energy density, allowing more energy to be stored within the same battery weight.

For heavy-lift UAVs, where battery weight directly contributes to the aircraft's overall payload, higher energy density helps maximize available energy without adding unnecessary weight. This provides a valuable advantage for applications requiring extended flight time and professional equipment integration.

Higher Discharge Voltage Platform for Consistent Power Output

Tattu UHV batteries feature a higher discharge voltage platform than conventional batteries, maintaining a higher operating voltage throughout discharge.

This higher voltage platform supports the power system's operating requirements and helps deliver consistent power during demanding flight operations, including takeoff, climbing, and sustained flight.

With four 41,000mAh batteries working together in a 2P2S configuration, the system provided the energy supply required for the Hercules UAV's heavy-payload mission.

Flight Performance

During the Nevada flight, the Hercules UAV successfully completed a 30-minute flight while carrying the 12kg HySpex VS-620 payload.

Key flight results included:

- 30-Minute Flight Duration: Completed a sustained flight with the HySpex VS-620 hyperspectral imaging system onboard.

- 12kg Payload: Carried professional hyperspectral sensing equipment throughout the mission.

- More Than 30% Battery Remaining: Landed with over 30% battery capacity remaining.

- Below 60% Throttle: Throttle remained below 60% throughout the flight, with additional power headroom available to accommodate demanding conditions, including strong wind gusts.

Reliable Power for Professional UAV Applications

High energy density and a higher discharge voltage platform are important advantages for UAV battery systems, particularly in applications involving heavy payloads and extended flight requirements.

In this Hercules UAV application, four Tattu 41,000mAh 6S UHV batteries powered a 30-minute flight with a 12kg payload, while maintaining more than 30% battery capacity at landing.

Tattu continues to provide advanced battery solutions for industrial UAVs, aerial sensing platforms, and other demanding unmanned aircraft applications, supporting diverse requirements for energy density, discharge performance, and flight endurance.
