As a technology leader in the cylindrical lithium-ion battery sector, YFH Power has consistently anchored its R&D on three core coordinates: high power, high safety and high capacity . Today, we present the complete real-world test data of the YFH18650-30XQ to demonstrate our solid technical strength in tabless technology.
Our Technical Breakthrough: Tabless Technology Empowering the 18650
Traditional single-tab designs are limited by concentrated current flow, resulting in high internal resistance and excessive heat. Through tabless process innovation, YFH Power's R&D team distributes tabs along the entire edge of the current collector, dramatically shortening the electron pathway and reducing internal resistance to the 3mΩ range within the standard 18650 form factor — achieving breakthroughs of 90A pulse discharge and 60A continuous output.

Max. Continuous Discharge | 40A / 60A | Stable output |
Instantaneous Pulse | 90A (2s) | Verified |
Fast Charging | 15A CC-CV | 12min to 85% |
Energy Density | 241 Wh/kg | Tested compliant |
Our Performance Test Report
Rate Discharge: capacity retention≥98%
Tested across seven current levels from3A to 60A, capacity retention remains ≥98%. This validates the stability of YFH Power's electrode formulation and electrolyte system under high-rate conditions, ensuring customer products perform reliably across all operating scenarios.
Cycle Life: capacity retention Over 80% After 500 Cycles
Under demanding 3A charge / 30A discharge conditions, the cell maintains ≥80% capacity retention after 500 cycles. This data directly supports power tool customers' core requirements for product lifespan and after-sales cost control.
High-Temperature Storage: Stored at 60°C for 60+ days
After 60 days at 60°C, remaining capacity stays ≥85% with recovery capacity ≥95%. This reflects YFH Power's R&D team deep mastery of electrolyte systems and interface stability.
