Runtime Extender for the NU40, NU43, NU50, and HC65 UHE Headlamps

The Nitecore Carbon Battery 6K Kit can double or triple the runtime of Nitecore headlamps such as the NU40, NU43, NU45, NU50, and HC65 UHE. By connecting directly to the headlamp, the Carbon 6K Battery Kit activates the headlamps' Performance Mode, ensuring long-lasting illumination and stronger brightness. It first draws power from the battery kit, maximizing its runtime before utilizing the headlamp's internal battery.

Lightweight and Comfortable

Weighing just over three ounces, its well-balanced design offers optimal weight distribution between front and back for a comfortable and secure wearing experience.

Reliable Connection

The Carbon Battery 6K Kit features a USB-C port for easy connection and charging, along with a quick-release clip that ensures a secure connection between the charging port, headlamp, and battery, guaranteeing reliable charging. To check the remaining power, simply short-press the Power Button to illuminate the three red power indicators. Additionally, for added safety, the kit includes a rear red light that serves as a signal light at night.

Contents in Package: Carbon Battery 6K, Headband, Bracket, USB-C to USB-C charging cable

Shipping

We ship to anywhere in the United States. We also ship to APO, FPO, Canada, Europe, Japan, and most other countries.

For domestic orders, buyers can choose first class mail (4-5 days) or priority mail (3 days) or express mail (1-2 days).

For international orders, we offer the option of first class international mail, which is the most inexpensive one. However, buyers should be aware that the international first class mail is not trackable. It can also take 2-8 weeks to deliver. We will try our best to declare the value and contents of the package according to buyer's instruction. But we will not be held responsible if any international first class mail is lost. There is a risk using low cost shipping and we hope our customers understand that.

We recommend our international customers choosing "international priority mail" which is faster (typically 12-21 days). Tracking and insurance will be provided at no extra cost. If you have any concerns or requirements about the shipping, feel free to contact us.
