This is a 2 cell battery container produced specifically for the Ferei HL65 Led Headlight.  It offers added flexibility and extended run times for the Ferei HL65 headlight.

This battery container connects to the Ferei HL65 headlight using an 88cm Ferei extension cable and can be used in place of the 1 cell battery pack supplied with the HL65.

This battery pack offers approximately double the runtimes of the standard 1 cell supplied with the HL65 Headlight and allows the HL65 to be worn on the head without the battery pack.  In this mode, the HL65 headlight alone, weighs just 119 grams.

To use, unscrew the connector on the HL65 Headlight between the switch and battery pack, remove the battery pack from the HL65 (no tools required) and connect the extension cable and battery container.

The extension cable connects to the light unit and battery using secure screw connectors.

NOTE: Extension cable and lithium-ion cells need to be purchased separately (not included).
