Grepow Unveils the Tattu 4.0 18S 35Ah: A New Standard for 80kg-Class Heavy-Lift UAV Operations

As a global leader in battery manufacturing with over 28 years of technological expertise, Grepow continues to push the boundaries of energy density and intelligent management. Through our dedicated UAV brand, Tattu, we are proud to announce the official launch of the Tattu 4.0 18S 35Ah LiPo Smart Battery.

This flagship power solution is specifically engineered for the 80kg-class heavy-lift drone sector—a market segment where performance, durability, and operational uptime are non-negotiable.

Powering the Next Generation of Industrial UAVs

In the modern landscape of precision agriculture and large-scale logistics, airframes and flight controllers are only as effective as the power systems driving them. The Tattu 4.0 18S 35Ah smart battery addresses the rigorous demands of these fields by merging extreme discharge performance with intelligent cycle management.

● Optimized for 80kg Payloads: Validated for the intense requirements of heavy-lift duty, ensuring reliable performance for large-scale agricultural spraying and cargo delivery.

● High-Discharge Stability: Provides the sustained power needed for consistent pump and nozzle performance in spraying missions and safe transit in logistics.

Key Innovations for Commercial Excellence

To support the high-frequency requirements of B2B fleet operators, the Tattu 4.0 18S 35Ah smart battery integrates several industry-first innovations:

1. Industry-Leading 9-Minute Rapid Charge

Minimizing ground time is essential for maximizing daily mission throughput. When paired with compatible high-power systems, the Tattu 4.0 supports true 9-minute fast charging. This allows operators to increase sortie counts without compromising the long-term health of the battery cells.

2. High-Current 500A Connector

Reliability at takeoff and during prolonged hovering is critical for heavy-lift platforms. The Tattu 4.0 features a newly developed 500A connector, providing substantial current headroom9. Notably, this interface maintains full backward compatibility with prevalent 300A interfaces, ensuring seamless integration into existing fleets.

3. Reduced Total Cost of Ownership (TCO)

For commercial enterprises, the economic value of a power system is measured by its lifespan. Through optimized cell chemistry and the intelligent Battery Management System (BMS), the Tattu 4.0 offers a 1000 guaranteed cycle lifespan under warranty. This significantly lowers the cost per flight, making it the most economically sound choice for high-frequency operations.

A Comprehensive Power Ecosystem

Grepow and Tattu provide more than just batteries; we deliver a total power management solution to ensure peak performance throughout the battery's lifecycle.

Global Availability

The Tattu 4.0 18S 35Ah Smart Battery is now officially available to enterprise clients and fleet operators across the European and American markets1.
