​Tattu 4.0 Smart Battery for Heavy-Lift UAV Field Testing

Case Overview

Application Background

Heavy-lift UAVs place much higher demands on the power system than standard drone platforms. During takeoff, climb, and payload-carrying flight, the battery must deliver strong current output to support large propellers and high-torque propulsion systems.

For industrial applications such as cargo transport, agricultural operations, and large UAV platforms, battery performance directly affects payload capability, flight stability, mission efficiency, and power system reliability.

This field test demonstrates how the Tattu 4.0 Smart Battery supports heavy-lift UAV missions with high-current discharge capability, fast charging performance, and smart battery communication.

Customer Challenge

Heavy-lift UAV platforms require a battery system that can provide stable power during high-load phases, especially during takeoff. When the aircraft carries a large payload, the propulsion system needs strong current support to lift off safely and maintain stable flight.

For pilots, battery turnaround efficiency is also critical. Faster charging means shorter waiting time between flights, helping pilots prepare the next mission more efficiently and improve the overall workflow of heavy-lift UAV operations.

Tattu Solution

The Tattu 4.0 Smart Battery is designed for industrial UAV applications that require high power output, fast charging, and intelligent battery management.

In this field test, the battery system supported a 256.2 kg cargo payload with a 25-minute flight time. With 270A continuous discharge capability, Tattu 4.0 can provide strong current support for heavy-lift UAVs during takeoff, climb, and payload-carrying missions.

The battery also supports 5C fast charging, allowing charging from 15% to 85% in around 10 minutes. This significantly shortens charging time, helps pilots prepare batteries faster, and improves operational efficiency between missions.

With DroneCAN-compatible communication, Tattu 4.0 can match UAV systems that require battery data feedback, diagnostics, and safety warning functions. This helps pilots better understand battery status during heavy-lift UAV missions.

Depending on the UAV platform, mission load, flight time target, and available battery compartment space, the battery quantity can be configured to match different application needs.
