The Fenix ALF-18 battery adapter allows the use of 18650 batteries in 21700 battery powered torches.
Made from PC and ABS plastics this adapter is the size of a 21700 battery and its internal bore fits the smaller 18650 battery. The adapter features copper plated contacts for excellent conductivity.

Please note that as 18650 batteries have lower capacity than 21700 batteries run times in your application will be correspondingly shorter.
