New Release! TATTU 5.0 Series | UAV Smart Battery

TATTU 5.0 Series Officially Launches: Powering a New Era of 100kg-Class Heavy-Lift UAVs

As agricultural and logistics drones move toward heavier payloads, longer duty cycles, and faster field turnaround, the battery system is no longer just an energy source. It has become the power core that determines flight stability, charging efficiency, thermal safety, maintenance speed, and overall operational productivity.

The TATTU 5.0 Series is developed for the next generation of 100kg-class heavy-lift UAVs, bringing together high-current cell technology, advanced thermal architecture, intelligent BMS control, high-power connectivity, lifecycle data access, and a dedicated ultra-fast charging ecosystem. Built around the concept of “The Power Core for Heavy-Lift UAVs,” TATTU 5.0 sets a new benchmark for demanding agricultural and logistics operations.

Dual-Tab Cell Architecture: High Current, Lower Heat Rise

At the heart of TATTU 5.0 is a new dual-tab cell architecture designed for high-current output and lower internal heat generation. By improving current collection efficiency inside the cell, the system supports stronger discharge performance while helping reduce temperature rise under heavy load.

The platform supports up to 12C continuous discharge and 6C fast charging, giving heavy-lift drones the power required for intensive takeoff, climbing, loaded flight, and repeated mission cycles. For operators working in agriculture spraying, heavy cargo transport, or high-frequency field deployment, this means more stable power output and faster turnaround between missions.

New Grille Cooling Structure: Built for Extreme Heat Dissipation

Heavy-lift UAV batteries face continuous thermal pressure during high-current discharge and fast charging. TATTU 5.0 introduces a newly engineered grille cooling structure with a hollow design that improves heat dissipation across the battery pack.

This structure helps create a more efficient thermal pathway, allowing heat to escape faster and more evenly. For large UAV platforms, better thermal control directly supports battery consistency, operational safety, and long-duration reliability under demanding field conditions.

Aerospace-Grade Aluminum-Magnesium Alloy: Lighter, Waterproof, Higher Pack-Level Energy Density

TATTU 5.0 uses an aerospace-grade aluminum-magnesium alloy housing to balance structural strength, weight reduction, and environmental protection. Compared with the previous generation, the upgraded housing helps reduce overall pack weight by approximately 30%, while maintaining the durability required for industrial UAV operations.

The structural upgrade also supports improved pack-level energy density and enhanced protection in outdoor environments. For agricultural and logistics drones, every kilogram saved can contribute to better payload efficiency, longer useful flight time, or improved mission flexibility.

500A Gold-Plated High-Power Connector: Stable Output from the Source

High-current UAV systems require more than powerful cells. The connection interface must also handle demanding electrical and mechanical loads. TATTU 5.0 is equipped with a custom 500A gold-plated high-power connector, engineered specifically for heavy-lift UAV power systems.

The integrated connector design improves current-carrying stability and helps reduce structural risks caused by vibration, frequent plugging, and high-load operation. By strengthening the power interface from the source, TATTU 5.0 provides a more reliable foundation for high-power UAV missions.

Industrial-Grade Low-Power MCU: Safer Long-Term Storage

For professional UAV fleets, batteries are not always used continuously. Long-term storage safety and low standby power consumption are critical to maintenance efficiency. TATTU 5.0 adopts an industrial-grade low-power MCU, reducing standby power consumption by 5× compared with the previous generation.

This low-power design helps support safer long-term storage and reduces unnecessary energy loss when batteries are idle. For fleet operators, it means less maintenance pressure, better storage confidence, and improved readiness when batteries return to active use.

High-Precision AFE Front-End Chip: More Accurate Power, Safer Operation

Accurate battery data is essential for heavy-lift UAV safety. TATTU 5.0 features a high-precision AFE front-end chip to improve the accuracy of voltage and current monitoring across the battery system.

With voltage measurement accuracy of ±3 mV and current sampling error of ±5 μV, the system provides a more reliable foundation for SOC estimation, battery protection, and operational decision-making. In heavy-load missions, more accurate data helps pilots and flight systems respond earlier, manage risk better, and maintain safer power control.

Standard Type-C Interface: Faster Data Export, Less Waiting

Battery data is becoming increasingly important for professional UAV maintenance. TATTU 5.0 comes standard with a Type-C interface, enabling faster and more convenient access to battery lifecycle data.

Compared with the previous generation, data export speed is improved by 11×, significantly reducing waiting time during inspection, maintenance, and after-mission analysis. For high-frequency UAV fleets, faster data access helps operators identify issues earlier, improve maintenance efficiency, and support more traceable battery management.

15kW Ultra-Fast Charging Ecosystem: Plug to Charge, Auto Stop When Full

TATTU 5.0 is not only a battery upgrade. It is part of a complete fast-charging power ecosystem. When paired with the dedicated 15kW smart charger, the system supports intelligent charging algorithms, automatic battery recognition, plug-and-charge operation, real-time monitoring, and auto stop when fully charged.

Under three-phase AC input, the system can charge the battery from 15% to 96% in approximately 14 minutes. This ultra-fast replenishment capability is designed for high-frequency operations where downtime directly affects productivity, especially in agricultural spraying and logistics delivery scenarios.

Industry-Leading Heavy-Lift Power for Agriculture and Logistics UAVs

The rise of 100kg-class UAV platforms is pushing power systems into a new stage. Agriculture drones require stable high-current output for large-volume spraying operations, while logistics UAVs demand dependable energy delivery for heavier cargo and more complex flight routes.

TATTU 5.0 responds to these industry demands with a system-level solution: high-current cells, advanced cooling, lightweight protection, a high-power connector, precision BMS sensing, faster data access, and a 15kW charging ecosystem. Together, these upgrades help heavy-lift UAV operators achieve stronger power performance, shorter charging cycles, safer fleet management, and more efficient daily operations.

A New Heavy-Lift Power Standard

The TATTU 5.0 Series represents more than a new battery generation. It is a complete intelligent power platform designed for the next era of heavy-lift UAVs.

With 12C continuous discharge, 6C fast charging, 5× lower standby power consumption, 11× faster data export, and 15% to 96% charging in approximately 14 minutes, TATTU 5.0 gives agricultural and logistics drone operators the power, efficiency, and reliability needed for the next stage of UAV productivity.  If you have any questions or needs, please feel free to contact us at info@grepow.com.
