Ultra-high power discharge Li-ion battery

Auline A45 INR-21700

Auline has been focusing on the development of ultra-high discahrge power battery products. We Launched the new generation of 21700 power battery INR21700-A45 4000MAH.
Auline A45 Battery has ultra low IR only 3.98mΩ and real 45A Continue output power performance compared with other manfacture.
This is a new starting point for low-impedance versions that are ideal for the high-end market for E-cigarette, Cordless Tools, flashlight, Hobby RC, WingsRC, FPV and many more applications.
