Powering the World's Most Efficient Drone Record with Tattu Semi-Solid State Technology

1. The Challenge: Surpassing the 3-Hour Mark

Renowned tech creator Luke Maximo Bell set out with a singular, ambitious goal: to build the most efficient multirotor drone ever made. His benchmark was the Sci-Fily Q12, an impressive piece of engineering capable of flying for 3 hours and 12 minutes on a single charge. To break this record, Luke knew that while massive 40-inch T-Motor propellers and high-efficiency motors were essential, the true bottleneck was the energy density of the power source.

2. The Solution: Tattu NMC Semi-Solid State Batteries

After calculating the optimal battery weight to be between 4,000g and 5,000g, Luke selected Tattu NMC Semi-Solid State batteries as the heart of his record-breaking attempt. These batteries provided a generational leap in performance:

  •Exceptional Energy Density: While traditional LiPo batteries typically offer around 160 Wh/kg with packaging, the Tattu Semi-Solid State batteries reach approximately 320 Wh/kg.

  •Double the Capacity: This technology allows the drone to carry twice as much capacity for the same weight compared to standard battery solutions.

  •Optimized for Endurance: Although semi-solid state batteries are not designed for high instantaneous current, they are the perfect choice for long-endurance projects where low RPM and steady power draw are required.

3. User Innovation: Pushing Optimization to the Limit

In a display of extreme engineering, Luke customized the Tattu batteries to shave off every possible gram, demonstrating the flexibility of our product for professional users:

  •Stripping for Performance: Luke removed the external protection and packaging from the batteries.

  •Connector Downsizing: He replaced the standard large XT90 connectors with lighter XT60 connectors, as the drone's specific current draw did not require the heavier hardware.

  •Significant Weight Savings: These modifications removed 180g of weight per battery. The total saving of 360g was equivalent to the weight of the entire carbon fiber frame, directly translating into increased flight time.

4. Results: A New Unofficial World Record

The performance of the Tattu-powered drone during the record attempt was flawless:

  •Superior Efficiency: At the 2-hour and 14-minute mark, the drone still had at least 33% battery remaining.

  •Breaking the Record: The drone officially surpassed the 3-hour and 12-minute mark while "holding position beautifully". 

  •Final Achievement: Luke landed the drone safely as the cells reached 2.95V, clocking a final time of 3 hours, 31 minutes, and 6 seconds.

5. Conclusion and Future Potential

This project serves as a definitive proof of concept for Tattu’s semi-solid state technology. By doubling the energy density of the power system, we helped Luke beat the previous record by nearly 20 minutes. Furthermore, Luke noted that in forward flight, power consumption drops from 400W (hover) to just 250W, suggesting that with Tattu batteries, a flight time exceeding 4.5 hours is within reach.
