In the demanding fields of modern precision agriculture and large-scale logistics, drone platforms are tasked with carrying heavier payloads, covering wider areas, and executing more consecutive missions—all while maintaining stringent operational uptime and cost-efficiency targets. The core enabler of this performance is no longer just the airframe or the flight controller, but the power system that drives it.

Tattu, a leader in professional drone power systems, is proud to announce the launch of theTattu 4.0 18S 35Ah Smart Battery. Designed as the definitive power source for 80kg-class heavy-lift drones, this battery represents a holistic solution that merges extreme performance with exceptional durability and intelligent management, setting a new benchmark for professional-grade applications in crop spraying and cargo delivery. 

Optimized for the Rigors of Heavy-Lift Operations

In commercial drone operations, where payloads routinely exceed 80kg and missions demand sustained high-power output, battery performance directly impacts operational efficiency, safety, and profitability. The Tattu 4.0 addresses these real-world challenges with an integrated solution that combines exceptional energy density, rapid charging capability, extended cycle life, and advanced thermal management — all optimized for the intensive demands of modern heavy-payload drones.

Key Innovations Delivering Tangible User Value:

1. Industry-Leading 9-Minute Rapid Charge Capability

In high-frequency operations such as large-scale crop protection or time-sensitive cargo delivery, minimizing ground time is critical. The Tattu 4.0 supports true 9-minute fast charging when paired with compatible high-power systems, enabling operators to significantly increase daily sortie counts and overall mission throughput without compromising cell longevity.

2. Robust 500A High-Current Connector

The newly developed 500A connector delivers substantial current headroom while maintaining full backward compatibility with prevalent 300A interfaces. This ensures stable, high-amperage discharge during demanding phases like heavy-lift takeoff, prolonged hovering, and continuous full-throttle spraying or transport — providing the reliability that professional fleets require in real-world conditions.

3. 1000 Guaranteed Cycles for Reduced Total Cost of Ownership

For commercial operators, the total cost of ownership is paramount. Through optimized cell chemistry, robust construction, and intelligent cycle management via the BMS, the Tattu 4.0 series achieves a remarkable 1000-cycle lifespan under warranty. This extended service life directly translates to a lower cost per flight and a significantly improved lifetime value, making it the most economically sound choice for high-frequency operations.

4. Tailored for 80kg Heavy-Payload Platforms

Every aspect of this battery is validated for the rigors of heavy-lift duty. It delivers the sustained high-discharge rates needed for large-scale agricultural spraying drones, ensuring consistent pump and nozzle performance. For heavy-payload delivery logistics, it provides the dependable power required for safe transit and precise operations, mission after mission.

A Total Power Solution: The Tattu Charging Ecosystem

Tattu understands that a battery is only as good as the system supporting it. We provide a comprehensive power management solution to ensure peak performance and safety throughout the battery's lifecycle.

High-Frequency Professional Solution: TA7200 PRO

For scenarios requiring maximum efficiency, the TA7200 PRO Charger delivers up to 7200W of power and a 120A charging current. This setup is specifically tuned to unlock the 9-minute fast-charging potential of the 18S 35Ah battery, catering to high-frequency, back-to-back mission cycles.

Versatile Deployment Solution: TA3000 PRO

The TA3000 PRO offers a balanced 3000W / 40A output, ideal for standard replenishment and decentralized operations where power infrastructure may vary.

Active Thermal Management: Smart Air Cooler

Heat is the primary enemy of LiPo longevity. Our custom-designed Smart Air Cooler for the Tattu 18S series automatically activates when temperatures exceed 30°C. By reducing average charging temperatures by 5°C, it preserves the structural integrity of the cells and ensures the battery is ready for immediate deployment after charging.

The Tattu Commitment: Industry-Leading Reliability

At Tattu, we understand that superior performance in heavy-payload drone operations requires more than just a battery — it demands a fully integrated ecosystem. The Tattu 4.0 18S 35Ah Smart Battery, combined with our proven charging infrastructure, represents a comprehensive advancement that empowers operators to achieve higher productivity, greater operational reliability, and lower long-term costs.

For professionals pushing the limits of 80kg spraying and delivery drones, the Tattu 4.0 delivers measurable value where it matters most: in the field, flight after flight.The Tattu 4.0 18S 35Ah Smart Battery is now available.
