Nitecore® Carbon Battery™ 6K Extended Headlamp Runtime Kit

Carbon Battery ™ 6K headlamp runtime kit is an external battery kit for compatible Nitecore® headlamps, intended for longer sessions where standard runtime may not be enough. It adds a 6,000mAh (21.6Wh) Li-ion power source via USB-C, making it suitable for night runs, hikes, work tasks and standby use where consistent light output is needed.

The battery mounts to the headband to keep the setup stable and well balanced during movement. A rear red safety light improves visibility from behind, and the 3-level power indicator provides a quick check of remaining charge.
