7.2V 8400mAh Ultra-Low Temp Li-ion Battery for Extreme Cold Environments

Arctic Research & Polar Expeditions

Designed to power critical equipment like meteorological sensors, ice-drilling tools, and satellite communication systems in temperatures as low as -40°C. Ensures reliable energy supply for multi-day polar expeditions and sub-zero data collection.

Emergency Rescue Operations in Frigid Zones

Enables uninterrupted operation of avalanche detection systems, thermal imaging devices, and emergency lighting in rescue missions. Withstands sudden temperature drops during high-altitude or Arctic rescues.

Cold Chain Logistics & Monitoring

Maintains stable performance in refrigerated transport systems, vaccine storage monitors, and IoT trackers for perishable goods. Operates seamlessly in -40°C to 55°C environments for 24/7 temperature-sensitive cargo oversight.

Keunggulan Teknis

1. Ultra-Low Temp Cell Chemistry: Proprietary electrolyte formulation prevents capacity loss below freezing, maintaining >85% efficiency at -30°C.
2. High-Power 21700 Cells: 45A continuous discharge supports heavy-load devices like industrial heaters or drone rotors.
3. Fast Charging Optimization: 0.5C charging restores 80% capacity in 90 minutes, ideal for time-sensitive cold-zone operations.
4. Military-Grade Durability: Reinforced casing resorts to vibration, dust, and moisture common in harsh environments.

Why Choose This Battery?

• Guaranteed Cold Performance: Independently tested at -40°C with <15% capacity drop vs. industry-standard 40% decline.
• Extended Storage Readiness: 3% monthly self-discharge rate ensures immediate use after long-term winter storage.
• Customizable BMS: Optional low-temp charging lockout and cell balancing for specialized applications.
