The Nitecore Extension Battery Case is a charging case built specifically for headlamps. The battery case connects directly to the headlamp, guaranteeing long-lasting illumination and stronger brightness. When connected to the Nitecore NU40, the NU43, or the NU50, the headlamps will automatically go into Performance Mode, creating a better lighting experience for the user. When the headlamp is on, it will first be powered by the battery case, followed by the built-in battery of the headlamp allowing it to maximize its runtime. Weighing less than three ounces, its well-balanced design provides an optimal weight distribution to the user for a comfortable and secure wearing experience.
The Extension Battery Case is compatible with high-capacity rechargeable batteries, excluding flat-top batteries. Equipped with an intelligent charging function, connect a USB cable to a USB-C adapter to begin charging the battery when not in use. For added safety, it features four red flashing lights to act as a signal light at night. Short press the Power Button for the power indicators to illuminate your remaining battery power.
