Power Engine: Ultimate Discharge Rate Enabled by Tabless Technology


Thanks to the ultra-low internal resistance and excellent thermal conductivity provided by the Tabless process, the YFH-INR21700-50Q achieves an energy density of 272 Wh/kg, with a sustained discharge capacity exceeding 15C and a peak discharge rate exceeding 30C. This on-demand, powerful performance perfectly demonstrates how the Tabless structure handles transient operating conditions—such as heavy-load takeoff, high-speed cruising, and sudden wind resistance during drone operations—ensuring a flight attitude as stable as a rock.

A Revolution in Thermal Management: Uniform Heat Dissipation Characteristics of the Tabless Structure

Another major technical advantage of the Tabless process lies in its complete transformation of the battery’s heat dissipation pattern. Current is evenly distributed across the entire edge surface of the electrode sheet, eliminating the localized high-temperature hotspots caused by concentrated current in traditional batteries. Combined with the internal heat dissipation channels within the cell, the YFH-INR21700-50Q maintains consistent performance across a wide temperature range of -20°C to 80°C. This inherent coolness, determined by the manufacturing process, ensures that industrial drones deliver stable and reliable power output even in extreme environments—whether in bitter cold or scorching heat.


Efficiency Leap: Ultra-Fast Charging Experience Enabled by Tabless Technology

The full-tab structure unlocks new possibilities for ultra-fast charging. The YFH-INR21700-50Q supports a maximum charging current of 15A, enabling an 80% charge in just 10 minutes. Tabless technology not only enhances discharge performance but also achieves an exponential increase in asset utilization during charging.


Conclusion

According to the industry outlook presented at UASE2026 in Shenzhen, the full-tab process is becoming a watershed moment for high-end cylindrical power batteries. As a company dedicated to the R&D and manufacturing of high-rate cylindrical cells, Yunfu Heng continues to deepen its commitment to the Tabless technology route, continuously optimizing the comprehensive performance of its cells in terms of power, energy density, fast charging, and reliability. In the future, the company will continue to be guided by market demand, launching more high-performance power products tailored for low-altitude applications such as drones and eVTOLs, and driving the high-quality development of the low-altitude economy through technological innovation.
