BHL18650-2000-HR High-Rate Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
1. 20C Extreme High Rate with Stable Instantaneous High-Current Output
Featuring an industry-leading 20C ultra-high discharge rate, the cell supports continuous 20C discharge and powerful instantaneous burst output to perfectly meet the instant startup requirements of high-power equipment. With specially optimized internal conductive structure, temperature rise is well controlled under high-current operation. The surface temperature remains below 60℃ during charging and ≤70℃ during discharge. It resists performance degradation after long-term repeated pulse operation, making it ideal for frequently started and stopped high-power devices.
2. Stable Discharge at -20℃ with Balanced All-Weather 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 2.5V. Outdoor winter equipment and cold storage devices in northern regions require no additional heating components, greatly reducing structural and thermal control costs.
3. 1500 Long Lifespan Cycles & Low Self-Discharge for Low-Maintenance Operation
The cell retains more than 80% of its rated capacity after 1500 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℃, it only requires simple supplementary charging after 12 months. It is highly suitable for intermittently used and long-term shelved emergency devices and RC equipment.
4. Full-Range Strict Safety Certification with Zero Thermal Runaway Under Pulse Loads
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 or explosion throughout all tests. The integrated steel shell provides excellent extrusion and impact resistance. Equipped with dedicated protection circuits, it achieves triple protection against overcharge, overdischarge and overcurrent, ensuring safe and reliable operation for high-power pulse equipment.
5. Superior Weather Resistance & Streamlined Standard PACK Assembly
After 10~55Hz three-axis vibration, 40℃/95% RH long-term damp-heat and 1-meter drop tests, the cell presents no deformation or liquid leakage and retains over 95% capacity. Cells from the same batch feature voltage difference ≤20mV, internal resistance difference ≤6mΩ and internal pack temperature deviation ≤5℃. Adopting universal 18650 dimensions with 100-piece shockproof inner box packaging, the cell supports only resistance welding and laser welding. Flexible series-parallel configuration requires no customized molds, enabling fast mass production for equipment manufacturers.
