In the fast-paced world of FPV racing and freestyle, pilots demand batteries that are lighter, stronger, and faster. Tattu R-Line Version 6.0 is the result of continuous engineering breakthroughs and extensive field validation. R-Line V6 is designed to meet the practical demands of FPV pilots — delivering high discharge power, quick response, and stable output throughout every flight.

With a 160C discharge rate, the series is optimized for instant acceleration, stable output, and peak consistency under demanding conditions.

Developed for Modern Flight Demands

Freestyle and racing disciplines push the limits of drone performance — and batteries are at the core. Tattu R-Line Version 6.0 was developed with close attention to the real-world feedback from professional pilots and evolving technical requirements. Every detail, from chemistry to structure, was refined to meet the call for faster response, lighter builds, and greater structural durability.

Key Technical Advancement

1. Nano-Level Power Delivery with 20% Lower Internal Resistance

The upgraded electrode design — featuring nano-particle materials and porous structure — shortens ion pathways and reduces internal resistance by 20%, significantly improving current responsiveness and throttle precision.

2. 3D Three-Dimensional Conductive Matrix

An advanced conductive framework built with graphite, carbon nanotubes, and graphene enables high-rate, stable discharge with improved electron flow. This ensures power delivery remains smooth and consistent even during demanding maneuvers.

3. Energy Density: More Power in Less Weight and Space

The R-Line V6 features a new generation of high-efficiency cell design, bringing more flight time without increasing size or weight — ideal for compact, high-performance builds.

Gravimetric energy density ↑17%

With a gravimetric energy density of 160Wh/kg, the R-Line V6 is lighter and holds more power than before. Compared to the V5 series, the overall weight is reduced by 16g, resulting in a 17% increase in weight-based energy density.

Volumetric energy density ↑26%

The internal layout is more compact and efficient, reaching a volumetric energy density of 316Wh/L. The total pack size is 15% smaller than the V5 series, while capacity is increased — a 26% gain in volume-based energy density.

The upgraded electrolyte formula also enhances safety and thermal stability, supporting long-term performance even under heavy usage.

4. Durable and Robust Construction

Built for reliability in high-intensity flight scenarios. R-Line V6 uses reinforced materials and structure to resist wear, heat, and external force:

• PET shell sealing for better wear and temperature resistance

• Fiber-reinforced structure to protect internal cells

• Aluminum L-guard design for improved structural stability inside the pack

Every structural upgrade contributes to consistent performance over the life of the battery — from build to flight.

5. Smart Layout for Better Flight Dynamics

SQ: Focused Center of Gravity, Enhanced Control

The short version features a compact, centrally balanced design that improves handling and stability in flight.

ST: Standard Dimensions, Flexible Placement

The stick version follows standard sizing, making it easy to fit into a wide range of FPV frames with greater mounting flexibility.

Lightweight Breakthrough. Carefree Flight.

R-Line V6 achieves the ideal balance between energy and agility — reducing weight while improving output. The result is a flying experience that's more responsive, stable, and efficient.
