Night Stick NS2 Features The Nightstick NS2-BATT is an 18650 lithium-ion cell built specifically for Multi-Fuel products that run on a single li-ion battery. Charging happens directly through a built-in USB-C port so owners can top off the battery with any standard USB-C cable rather than needing a dedicated charger. Because it has no recharge memory effect the battery can be charged at any point in its discharge cycle without shortening its usable life. That flexibility makes it easy to keep topped off between uses rather than waiting for a full discharge first. Finished in White for easy visual identification against other batteries the NS2-BATT is sold individually so users can keep a spare on hand or replace a worn cell. Lithium-ion 18650 cells are a common standard across many tactical flashlights giving this battery broad usefulness beyond just Nightstick-branded lights. Keeping a charged spare on hand means a flashlight is never out of commission for long which matters for duty home defense or everyday carry use. For Nightstick flashlight owners who want a reliable USB-C rechargeable power source the NS2-BATT is a simple practical addition.
