    Beast 21700
    Holy crap, this 21700 with built-in USB-C is a game-changer in my Defender P17, it handles those insane tactical bursts like a champ! Protection circuit is rock solid, no worries about overheat or shorts even when I'm hammering turbo modes outdoors. Charging right in the P17 with USB-C cable? Genius, no fumbling with chargers in the field. Already at 100+ cycles and still going strong!!!  Runtime on P17's workhorse modes absolutely crushes standard cells. It is power in one badass package

    I’ve basically switched over to using only these Acebeam 21700 USB‑C batteries now and don’t even bother with a separate charger anymore. The built‑in USB‑C port makes topping them up as easy as charging a phone, and the 5000mAh capacity with up to 15A discharge current is more than enough for all my flashlights. With the integrated protection circuit against short circuit, overcharge, over‑discharge, and overheating, plus a rated 500 charge cycles.....basically all I need
