Functions and Feature

Breakthrough Temperature Limits: The extreme cold-weather model can withstand temperatures as low as -80°C, breaking the traditional “forbidden zone” of lithium batteries.

High-Rate Start-Up Performance: Large-capacity pouch batteries, such as the 115Ah model, are optimized for cold starts in armored vehicles and heavy machinery, offering strong instantaneous discharge capabilities.

Lightweight Design and High Energy Density: The 18650-3500mAh(2500mAh) range balances low-temperature performance with extremely high energy density, significantly improving the low-temperature endurance of drones.

Stable Physical Structure: The pouch battery boasts excellent heat dissipation and shock resistance, making it more suitable for high-dynamic mobile platforms such as robotic drones.

Application Scenarios

Specialized Equipment: Cold start power supplies for heavy equipment/armored vehicles, vehicle auxiliary power units (APUs), and support for missions in cold regions.

Intelligent Robots/Mechanical Dogs: Polar/border patrols, disaster relief, and automated exploration in frigid zones.

Industrial/Specialized Unmanned Aerial Vehicles (UAVs): Cross-altitude monitoring, winter defense patrols in northern regions, and high-altitude reconnaissance.

Single-Person Equipment Power Supplies: Tactical communication terminals, night vision devices and individual reconnaissance equipment, and cryogenic flashlights.
