Chart shows typical Nora 4 run times using Nora box with 7000mAh Nora battery pack.


The four factory default light settings are highlighted 1 - 4. Other light level combinations are configurable options using remote programmer.  

An obvious feature first!!  Return of the robust, caver friendly, stainless steel 'clippity clips', as used by the Nora2 box (from 2013). You kept nagging us, and so they're back to stay.


Easy to open and remove batteries for charging, or swapping out on those very long (24+ hour) trips that may require battery replacement. 

More about the 'clippity clips' !!  The lid is neatly attached to the battery box with captive bolts. This makes it extremely difficult to lose lid.


There is no need for a remedial tether to secure the lid to the box. Such a solution was neccesary for Nora1, but that was a long time ago (2010). 


Nora 4 battery box attaches to helmet with discrete fixing screws.


No tarting around ! We went straight for the battered ECRIN ROC.






An alternative battery box attachment method, with elastic shock cord.


As will all Little Monkey battery boxes since 2008, the Nora 4 box has machined groove purposed for this option. Spot the subtle difference between the two shock cord photos !!


CNC Machined from aluminium alloy, the Nora 4 box benefits from excellent strength to weight ratio and thick wall section at wear points! The Nora 4 box is hard anodised for increased corrosion and wear resistance, $$$ versus regular sulphuric anodising (colour anodising etc), but worth it we feel.


Weighing approx. 160g it is bomb proof, but still a relative joy on the back of your caving helmet versus 3 or 4 cell boxes, balancing superbly with front mounting Nora or Edna lamps. 


Nora 4 battery box has a thick wall section at the top edge of lid, most exposed to wear (particularly if doing a lot of low hands and knees caving). The sealing edge is well away from the exposed top edge, and hence protected from wear.


In order to optimise our battery box design, we evaluate and dismiss many other options. One such example, an 'inset lid' design was dismissed because of concerns that wear at the thin section sealing edge will inevitably lead to water ingress.


The NORA battery box is available with both Edna 2 and Nora 4 lamps.


Nora 4 Battery Box  

The Nora 4 battery box offers the necessary robustness and water tightness to protect li-ion batteries from damage. Nora 4 box accomodates both simple 1s2p li-ion battery packs and individual 18650 li-ion batteries. Nora 4 box also accomodates 3xAA batteries, a useful option for remote expedition or reserve.
