Backup for USB-C 21700
"As 21700 emerge as the new go to over 18650, the manufacturers are leaning towards proprietary batteries in chemistry and size. No exception here. Like the Olight 21700, the Fenix 21700 is longer due to the USB-C. Thus you cannot swap 21700s between most lights. I have this Fenix dedicated as backup for my WellTool W4 which uses same USB-C 21700 longer battery."
