FUNCTIONAL DESCRIPTION
ur batteries are engineered with advanced lithium-ion chemistry and a proprietary low-impedance electrolyte, enabling a sustained 3C charge rate without compromising cell stability.
80% Charge in 15 Minutes
Compared to standard 1C batteries that require 60–90 minutes to charge, our 3C technology slashes downtime by over 70%.
The "2-Battery-1-Drone" Continuous Workflow
For operators, this means Zero Waiting Time. You no longer need to carry 6–10 batteries to the field. With a 3C fast-charge cycle, 3 batteries are enough to keep one drone in the air indefinitely (2 charging, 1 flying). This drastically reduces your initial investment in battery inventory but doubles your daily operational acreage.
High-Rate Cell Chemistry & Multi-Tab Ultrasonic Welding
Low-impedance electrode design and Z-stack structures,allows for a sustained high-current output of 30C+ Burst and 15C Continuous discharge.
Minimal Voltage Sag & Superior Thermal Stability
While standard batteries experience a "voltage drop" under heavy load—causing power loss—our cells maintain a flat discharge curve. By reducing internal resistance (IR < 0.8mΩ), we minimize heat generation during peak output for aggressive maneuvers.
Ultimate Control & Mission Safety
-
Precision Maneuvering: When drone fighting strong headwinds, you get instantaneous throttle response.
-
Prevent "Low-Voltage" Crashes: Eliminate the risk of sudden power-offs during high-torque demands (like emergency braking or rapid climbing), protecting your expensive equipment and payloads.
-
Extended Hardware Life: Stable voltage means your ESCs and motors run more efficiently, reducing wear and tear.
Our batteries integrate A-Grade High-Stability NMC cells(Wide-Temperature Electrolyte) with a High-Efficiency Heat Dissipation housing.
Zero Performance Degradation in Extreme Environments
Unlike standard batteries that lose up to 40% capacity in freezing temperatures or risk thermal runaway in high heat, our technology maintains 95% energy retention in sub-zero conditions.
Fly and Store Anywhere, Anytime
Stop waiting for the weather to clear. Whether it’s an early spring spraying mission in 0°C or a mid-summer survey in 45°C, your drones stay in the air with consistent power delivery .
High-Nickel NCM Chemistry
The cell of this batteries achieve a gravimetric energy density of up to 195Wh/kg and a volumetric density exceeding 405Wh/L.
More Power, Less Mass
Compared to conventional lithium batteries, our cells offer a 20-30% increase in energy storage within the exact same physical footprint. This is achieved through a proprietary "stacking" process that minimizes dead space and a lightweight, high-strength composite casing that reduces "parasitic" weight without sacrificing structural integrity.
Extended Range & Maximum Payload Capacity
For UAV Operators: Every gram saved is a second earned. Our high density extends flight times, allowing for larger area coverage per mission or the ability to carry heavier.
Lower Transport Costs: Since you get more energy per kilogram, shipping and logistics costs per kWh are significantly reduced, improving your overall bottom line.
