7.2V 8400mAh Li-ion Extreme Cold Weather Battery Pack

Polar Research & Scientific Instrumentation

Engineered for sub-zero environments, this battery delivers reliable power to data loggers, environmental sensors, and communication devices in Arctic/Antarctic expeditions. Its ultra-low temperature performance ensures continuous operation of critical equipment at -40°C, supporting long-term research missions without power degradation.

Frigid Zone Emergency Rescue Systems

Optimized for life-saving equipment like GPS trackers, thermal imaging devices, and medical tools in extreme cold. Maintains stable voltage output during rapid discharge, enabling uninterrupted operation of rescue drones, emergency beacons, and survival gear in blizzards or alpine missions.

Low-Temperature Industrial Automation

Powers robotics, remote telemetry systems, and cold-storage sensors in oil/gas pipelines, freezer warehouses, and Arctic mining operations. Withstands rapid temperature fluctuations (-40°C to 55°C) while sustaining high-current output for automated machinery in harsh climates.

ข้อได้เปรียบทางเทคนิค

Utilizing four 21700 cells in a 2S2P configuration, this pack combines high energy density (535 Wh/l) with BMS protection for overcharge/discharge prevention. The low-impedance (<15mΩ) cells enable 45A continuous discharge, while advanced electrolytes minimize capacity loss at sub-zero temps. Customizable connectors and housing ensure seamless integration into mission-critical systems.

Why Choose This Battery?

Designed for applications where failure is not an option, it outperforms standard Li-ion packs in extreme cold with <20% capacity loss at -40°C. The 8.4Ah capacity and 0.5C fast charging reduce downtime, while its 500-cycle lifespan (80% retention at 25°C) ensures cost efficiency in remote deployments.
