About the Cell

The Tenpower 25SG cell features a cylindrical 18650 form factor, optimised for UAV applications. With a nominal capacity of 9.0 Wh and 2.5 Ah, it provides a reliable energy source for various drone operations. Its volumetric energy density of 511 Wh/l positions it around the median of the database, ensuring efficient space utilisation. The gravimetric energy density of 200 Wh/kg is also competitive, allowing for lightweight battery packs that do not compromise on performance. The cell's maximum continuous discharge rate of 35 A, which is in the top-quartile compared to the database median of 30 A, ensures it can handle demanding power requirements without overheating. This makes it an ideal choice for high-energy density drone batteries, particularly in applications where weight and space are critical factors.

Application Challenges

In the EVTOL sector, maximising flight time is crucial. The challenge lies in optimising cell selection, duty cycle, and flight speed to achieve this goal. The Tenpower 25SG cell's specifications, including its high energy density and robust discharge capabilities, directly address these challenges. For instance, the ability to deliver a maximum continuous discharge of 35 A allows drones to perform efficiently under load, which is essential for extended missions. Additionally, the cell's volumetric energy density of 511 Wh/l ensures that UAVs can carry more energy without significantly increasing weight, thus enhancing overall flight endurance. In harsh environments, where temperature fluctuations can affect battery performance, the Tenpower 25SG is designed to maintain reliability and efficiency, making it suitable for long endurance drone batteries.

Why this Cell

The Tenpower 25SG cell is specifically designed to meet the demands of UAV applications, particularly in maximising flight time. With a maximum continuous charge rate of 10 A, it allows for rapid recharging, which is essential for operational efficiency. The cell's volumetric power density of 7,151 W/l is among the highest in the database, providing exceptional performance for high discharge rate UAV batteries. This capability is crucial for applications requiring quick bursts of power, such as take-off and heavy lifting. Furthermore, the gravimetric energy density of 200 Wh/kg ensures that the battery remains lightweight, which is vital for improving UAV mission endurance. By choosing the Tenpower 25SG, operators can confidently optimise their drone designs for extended flight times and enhanced performance.

How Model-Based Design Helps

Simulation and model-based design play a pivotal role in selecting the right battery cells for UAV applications. By simulating load profiles, thermal behaviour, and voltage response, engineers can predict how the Tenpower 25SG cell will perform under various conditions. For example, modelling the thermal rise during high discharge scenarios helps identify potential overheating issues, allowing for proactive thermal management strategies. Additionally, simulations can assess the usable energy across different flight speeds, ensuring that the cell can deliver the required thrust throughout the mission. This approach not only aids in selecting the highest performing cell but also reduces the need for costly trial-and-error testing. By leveraging cell-specific data, operators can make informed decisions that enhance drone powertrain efficiency and overall mission success.
