Fitorch ET25 extension compartment diagram showing a P25 flashlight, tube, tail cap and 26650 battery

Double the Runtime With One Extra Tube

Screw the ET25 onto a P25 body and a single 4500mAh 26650 cell replaces the short 26350, improving runtime by roughly 2.5 times.

26350 for the Pocket, 26650 for the Night

Keep the compact cell for everyday carry, then add the extension tube and a 26650 when a long shift or a night trail matters more than size.

The Same Aerospace Aluminum as the Host

Machined from high-strength alloy and mil-spec hard anodized, so the extension matches the finish, threads and durability of your P25.
