Streamlight SL-B50 Rechargeable Lithium-Ion Battery Pack$61.73$27.09
Availability: In Stock
The Streamlight SL-B50 USB rechargeable battery is a protected lithium-ion power cell built for select Streamlight tactical lights and headlamps. If you run Streamlight gear in the field—whether that's a ProTac 2.0 headlamp for hands-free work or a rail-mounted light on a rifle or shotgun—the SL-B50 eliminates the need to constantly buy disposable batteries. A single charge lasts through serious use, and the battery recharges at least 500 times over its lifespan, making it a practical and economical choice for hunters, shooters, and outdoors folks who depend on reliable illumination.
The USB-C charging port means you can top up the SL-B50 using any standard USB-C charger or power bank—convenient when you're in camp, at the range, or between trips. A full charge takes about 6 hours, and the integrated status indicators (red while charging, green when full) let you know exactly where your battery stands. Built-in safety circuitry protects against overcharge and overdischarge, so you don't have to babysit the charger or worry about damaging the cell.
At just 3 ounces and under 3.3 inches long, the SL-B50 is compact enough to stash in a pack or vest pocket without taking up real estate. If you've invested in Streamlight's modern rechargeable lights, this battery is the backbone that keeps them ready to go.
