Application
Polar Research & Arctic Exploration
Engineered for extreme cold environments, this battery powers critical polar research equipment such as ice-core drills, thermal imaging systems, and portable weather stations. Its ultra-low temperature resilience (-40°C operation) ensures uninterrupted energy supply for scientific data collection in Arctic and Antarctic expeditions.Frigid Zone Rescue & Emergency Response
Optimized for cold-zone rescue missions, it supports avalanche transceivers, hypothermia treatment devices, and emergency communication units. The fast-charging capability (0.5C max charge current) and integrated BMS enable rapid deployment in life-saving operations under sub-zero conditions.Low-Temperature Industrial Sensors & Drones
Ideal for drones and IoT sensors in cold-chain logistics, permafrost monitoring, and oil/gas pipeline inspections. The compact size (65×80×65mm) and lightweight design (480g) enhance portability for aerial and fixed installations in extreme climates.Outdoor Survival & Expedition Gear
Powers high-drain devices like heated clothing, GPS trackers, and LED floodlights for mountaineering or winter camping. With a volumetric energy density of 610 Wh/l, it extends runtime for energy-intensive equipment in remote-Low Temperature environments.Medical & Military Cold-Environment Systems
Certified for CE/RoHS/UN38.3 compliance, this battery meets safety standards for medical defibrillators, night-vision devices, and military communication systems. Its 500-cycle lifespan guarantees reliability for mission-critical operations in harsh conditions.Technical Advantages
Crafted with advanced lithium-ion technology, this 10.8V 8.4Ah battery outperforms traditional lead-acid alternatives with 35A max discharge current and 20mΩ internal resistance for high-power demands. Its 3S3P configuration (nine 18650 cells) ensures stable voltage and capacity, while the wide operating temperature range (-40°C to 55°C) makes it indispensable for cold-zone applications.Why Choose This Battery?
