BHL084080-2.2Ah-UHR Ultra-High-Rate Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. 80C Ultra-High Pulse Rate with Extreme Instantaneous Current Output
Featuring an industry-leading 80C ultra-high discharge rate and ultra-low internal resistance design, the cell delivers powerful instantaneous burst current with zero voltage drop or power attenuation during instant equipment startup and pulsed operation. It achieves excellent temperature control under high-power discharge, with the surface temperature not exceeding 70℃ during short-term high-current output. Resisting aging under frequent pulse start-stop cycles, it is perfectly tailored for special pulsed equipment that requires millisecond-level peak current output.
2. Stable Low-Temperature Pulse Discharge at -20℃ with Balanced All-Climate Performance
Operating temperature range: charging 0℃~40℃, discharging -20℃~55℃.
The cell retains ≥95% capacity at 55℃ high temperature, delivers full rated capacity at room temperature and maintains 95% capacity at 0℃, while reserving over 80% capacity at -20℃ low temperature with a low-temperature discharge cut-off voltage of 2.3V. Lightweight pulsed devices operating in winter outdoor and cold storage environments require no heating modules, ensuring robust low-temperature pulse performance and greatly simplifying the overall thermal control structure.
3. 8mm Ultra-Thin Lightweight Pouch Cell for Confined Space Integration
Adopting ultra-thin aluminum-plastic film packaging with a thickness of merely 8mm and a single-cell weight below 55g, the compact and lightweight cell can be embedded in narrow internal cavities of various miniature devices. Free from the dimensional limitations of cylindrical cells, it lowers the design threshold for ultra-slim equipment and integrates outstanding ultra-high pulse discharge performance within limited installation space, balancing lightweight structure and powerful burst output.
4. 1000 Stable Cycles & Low Self-Discharge for Long-Term Shelf Storage
The cell retains more than 80% rated capacity after 1000 standard charge-discharge cycles and maintains ≥85% residual capacity after 30-day full-charge static storage at room temperature with ultra-low self-discharge rate. For long-term storage, a 10%~35% state of charge is recommended. When stored in dry environments at -20℃~45℃, only supplementary charging is required after 12 months, making it ideal for long-term sealed pulse emergency equipment.
5. Full-Range Safety Verification & Convenient PACK Assembly
The cell has passed comprehensive safety tests including overcharge, deep overdischarge, external short circuit, 135℃ thermal shock, high-low temperature cycling, three-axis swept vibration and six-direction drop, with zero fire, leakage or explosion throughout all tests. Cells from the same batch feature 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. No customized housing is required, enabling efficient mass production for small-batch ultra-thin pulsed equipment.
Ⅱ. Industry Application Scenarios
Miniature Pulse RC Models / Racing Drones
The 80C ultra-high rate fully meets peak current demands for instantaneous acceleration and diving of aircraft. The ultra-light and thin structure reduces overall body weight, ensuring stable low-temperature power output without attenuation during winter outdoor flight while balancing endurance and explosive performance.
