Nora ABS 'clippity clip' battery box  (individual 18650 batteries)   New for 2025.

Alternative 3.7v Nora battery box, for use with individual 18650 batteries. 

Designed for use with 2x 18650 protected 18650 batteries in parallel at 3.7v (batteries up to 69mm).  We do not recommend using unprotected 18650 batteries.  Do so at your own risk.  The holder has a fuse which will blow and provide a level of protection should you inadvertently fit one battery the wrong way around and cause a direct short.  If you do so, the holder will then operate from one batttery only, and fuse / holder will need to be replaced when convenient.  It is good practice to charge and discharge batteries as matched pairs. 

Manufactured from ABS. Light weight 130g (excluding batteries).  Helmet mounting.  Robust, waterproof construction, should stand up to plenty of caving, see note below*.  It should be noted that battery bounce is a common characteristic of boxes that accommodate individual batteries subject to impact, resulting in momentary disconnection of batteries / loss of power. The box has been designed to mitigate this as much as possible, but could occur with a severe impact.    

LH (left hand) cable gland standard version suitable for Edna / Nora lamps. Nora lamp cable dia 4.8mm, but should cope with a range of cable diameters approx 3-5mm (suitable gland sealant is never a bad idea depending on cable used).  RH (right hand) cable gland version available (on request), for conversion of original Petzl Duo to 1s2p 3.7v li-ion battery pack. 

Soldering is required to connect lamp cable in to the battery box.
