Night Stick NS1 Features The Nightstick NS1-BATT is a 16310 lithium-ion rechargeable battery purpose-built to power the NS1 flashlight platform. Lithium-ion chemistry gives it a strong consistent voltage curve through its discharge cycle which helps keep the NS1 s output steady rather than dimming early like some disposable cells. Charging is handled through a USB-C port built into the cell itself so there is no separate charging cradle to carry or lose track of. This makes topping off the battery as simple as plugging in any modern USB-C cable at a desk in a vehicle or from a portable power bank. Keeping a spare NS1-BATT on hand means a depleted light can be back in service in minutes rather than left dark until a charger is available. The black finish matches the NS1 s housing for a clean uniform look whether the light is carried on a duty belt or tucked in a range bag. Rechargeable batteries also cut down on the ongoing cost and waste of disposable cells for anyone who uses their light regularly. For NS1 owners who want a dependable backup or replacement cell the Nightstick NS1-BATT is a simple direct-fit solution.
