Extremely High Discharge Rate (70C):
The core feature of this cell is its ability to deliver a continuous discharge current of up to 1225 Amps (70C * 17.5Ah). This enables incredible power output for its size and weight.
Low Internal Resistance :
Engineered with specialized materials and design to achieve very low internal resistance, which minimizes heat generation during high-current discharge, maximizes efficiency, and preserves voltage stability under load.
High Power Density:
While energy density is optimized for capacity, this cell excels in power density, delivering more watts per kilogram than standard energy cells. This is crucial for applications where minimizing weight is paramount.
Robust Cycle Life under High-Rate Conditions:
Built with rugged electrodes and stable electrolyte formulations to withstand the mechanical and chemical stresses of ultra-high current cycling, ensuring longevity even in the most demanding use cases.
Enhanced Thermal Stability:
The cell is designed with advanced thermal management properties to safely dissipate the heat generated during extreme operation, a critical factor for safety and performance.
Prismatic Form Factor:
The rectangular shape provides excellent mechanical stability, simplifies cell integration into custom battery packs, and allows for efficient heat transfer to cooling systems.
This high-rate cell is specifically designed for applications that require immense power in short durations:
High-Performance Drone (UAV/UAS):
Primary power for racing drones, heavy-lift commercial drones, and eVTOL (electric Vertical Take-Off and Landing) aircraft where rapid climb and agility are essential.
RC Vehicles:
Powers competitive-grade radio-controlled cars, boats, and aircraft that require extreme acceleration and top speed.
Power Tools:
Ideal for professional-grade cordless power tools such as concrete breakers, circular saws, and industrial drills that demand high torque and sustained power output.
Starting, Lighting, and Ignition :
For high-performance vehicles, aviation, and heavy machinery requiring high cranking power.
Backup Power & High-Power UPS:
Provides critical high-current support for server racks and telecommunications infrastructure during power outages.
