A Little Bigger Battery Is A LOT BETTER

More Power + Longer Runtimes!

BRIGHTER flashlights need more POWER to maintain high output levels for longer time periods.

How can an EDC flashlight like the Fenix E35 V3.0 emit 3000 lumens and still be so compact? Easy, Fenix 21700 batteries have 43% more battery capacity compared to a 3500mAh 18650, which helps these brighter lights operate at higher lumens while maintaining acceptable runtimes!

Despite this extra "juice", the 21700 isn't that much larger than the standard 18650. The battery is still smaller than an inch in diameter which is perfect for everyday carry & compact tactical flashlights.
