Nstick Ns2-Batt Li-Ion Usb-C Battery - 18650

The Bayco Nstick NS2-BATT Li-Ion USB-C Battery is a dedicated 18650 replacement cell designed for Nightstick NS2 flashlights and compatible gear. If you run tactical, work, or outdoor flashlights regularly, a spare rechargeable battery eliminates the downtime of disposables and keeps you powered in the field. This lithium-ion cell integrates USB-C charging—a modern, universal standard that works with phone chargers, power banks, and charging hubs you likely already own, making field recharges and emergency top-ups genuinely practical.

Built as a direct fit for the NS2 platform, this battery delivers the capacity and performance your light expects, with no compatibility surprises. Whether you're staging a hunting camp, maintaining duty gear, or keeping a tactical light in your truck, having a charged spare eliminates the frustration of a dead light when you need it most.

USB-C recharging beats the single-use battery trap: you'll save money over time, reduce waste, and always have a backup without planning special trips to find replacements. For anyone serious about their flashlight reliability, this is a straightforward upgrade worth the investment.
