BHL1070185-15Ah Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. Stable High-Power Output Down to -40℃ Ultra-Wide Temperature Range
Operating temperature: charging from 0℃ to 40℃, discharging from -40℃ to 55℃.
The cell retains ≥95% capacity at 55℃, delivers full rated capacity at 25℃ room temperature, and maintains 95% capacity at 0℃. It keeps over 80% capacity under -40℃ extreme cold conditions with a low-temperature cut-off voltage of 3.0V. No external heating module is required, enabling full-load operation of high-power equipment in cold northern regions, cold storage and high-altitude environments. It simplifies the overall temperature control structure and reduces equipment R&D costs.
2. 15Ah Large Capacity + 25C Ultra-High Pulse Discharge
The 15Ah large-capacity single cell effectively extends continuous operating time of equipment. Designed with 25C high discharge rate, it supports 275A continuous current and 600A instantaneous peak current output, ensuring no obvious voltage drop during equipment startup and heavy pulse-load operation. Optimized internal conductive structure limits the maximum surface temperature within 70℃ during short-term charge and discharge, preventing cell aging and attenuation under long-term frequent high-power start-stop cycles.
3. 600 Stable Cycles & Low Self-Discharge for Easy Storage
It maintains over 80% rated capacity after 600 standard charge-discharge cycles and retains ≥85% residual capacity after 30-day full-charge static storage at room temperature with low self-discharge loss. For long-term storage, a 10%~35% state of charge is recommended. Stored in dry environments of -20℃~45℃, it only requires simple recharge once a year, making it ideal for long-term stored high-power emergency field equipment.
4. Full-Range Strict Safety Verification with Zero Thermal Runaway Risk
The cell has passed comprehensive abuse tests including overcharge, deep overdischarge, external short circuit, 135℃ thermal shock, high-low temperature alternating cycle, three-axis swept vibration and six-direction drop. No fire, liquid leakage or explosion occurs during all tests. The deformation-resistant aluminum-plastic composite shell, matched with professional protective circuits, provides triple protection against overcharge, overdischarge and overcurrent, meeting high safety standards for military and industrial high-power equipment.
5. Standardized Pouch Cell for Efficient High-Power PACK Assembly
Featuring a standardized pouch size of 185×70×10mm, cells from the same batch have voltage difference ≤20mV, internal resistance difference ≤6mΩ and internal PACK temperature deviation ≤5℃. Only resistance welding and laser welding are permitted, while tin welding is prohibited. There is no quantity limit for series and parallel connection. Equipped with fuses in series circuits, customized metal shell molds are not required, greatly improving mass production efficiency of high-power energy storage modules.
Ⅱ. Industry Application Scenarios
High-Power Model Aircraft & Industrial UAVs in Cold Regions
The 25C peak current supports rapid climbing and diving of aircraft, while the 15Ah large capacity extends flight endurance. It maintains stable power performance at -40℃ in winter outdoor environments, perfectly suitable for heavy-duty surveying and inspection UAVs.
Heavy-Duty Vehicle Low-Temperature Emergency Starting Power Supply
The 600A instantaneous peak current meets the low-temperature startup demands of large construction machinery and trucks. It maintains stable voltage after long-term static storage in extreme cold with negligible power loss during vehicle-mounted standby.
High-Power Pulsed Industrial Equipment
Applicable for heavy impact tools and mining pulse detection instruments in northern industrial plants. It delivers stable cycling performance under high-frequency start-stop conditions and provides consistent high-power output in cold storage and open-air workshops throughout the year.
High-Power Field Energy Storage for Polar & Plateau Regions
Ideal for high-power outdoor power stations and heavy-duty inspection equipment for oil and gas pipelines in alpine and polar regions. It operates stably under extreme day-night temperature differences, and low self-discharge reduces frequent manual remote maintenance.
High-Power Individual Rescue Equipment
Suitable for field heavy-duty pulse lighting and high-power emergency rescue startup modules. The combination of large capacity and instantaneous high current ensures sufficient endurance for multi-day field missions in severe cold environments.
