Nitecore Carbon Battery 6K Kit – Runtime Extender for NU40/NU43/NU45/NU50 & HC65 UHE

Extend Your Headlamp Runtime with the Carbon Battery 6K Kit

The Nitecore Carbon Battery 6K Kit presents a lightweight power boost designed for select headlamps, offering a practical way to stretch outdoor sessions without compromising balance or comfort.

When you connect the kit to compatible headlamps, you may see a notable increase in usable run time. The setup emphasizes a low-profile profile on the back of the headband, helping to maintain a natural feel even during extended use. A rear red light adds a subtle safety cue in low-light environments, helping you stay visible without adding clutter to the front beam.

The kit is designed with real-world use in mind. The quick-release cable enables a reliable, fast connection between the headlamp and the battery pack, while the cable can be tucked neatly around the headband to minimize snagging during activity. At just a little over three ounces, the carbon-fiber construction balances strength and weight, making it a comfortable addition for long night runs, work shifts, or late-night setup sessions.
