Rude Nora 3-dive

Nora 2xs Battery Box

gallery/nora3.9s

Our Nora 2xs battery box (as originally used with the Nora 2 lamp) has presently been retained in our product range, and is available paired with the Nora 3-dive light. Weighing a little more than the new 3-dive box at 120g (around 215g with battery pack) it is still very light on the back of your caving helmet and also balances well with the Nora 3-dive lamp.

 

The Nora 2xs box features robust caver friendly lid closure clasps, and like the 3-dive box can accommodate a range of batteries, including our 5.2Ah non-proprietary battery packs*, individual 18650 cells, and AA batteries. You are certainly not restricted to a single battery option as is typically the case, and which might involve expensive proprietary manufacturer packs.  

 

Nora 2xs battery boxes are individually pressure tested to 7 bar 60m. We are not promoting this as a solution for cave diving! The 2xs box of course offers the necessary robustness and water tightness to protect li-ion batteries from damage, but to maintain depth rating over time we would consider it necessary to regularly inspect and periodically adjust the catch plates in order to maintain optimal closure pressure of the clasps, and with the best will in the world people don't. Nora 3-dive lamps supplied with 2xs battery boxes are by default only tested to 7 bar.

 

As with the 3-dive box, the 2xs box is constructed from delrin (with alloy lid), typical of diving canister lamps, and benefits from a thick wall section with excellent strength to weight ratio. The Nora 2xs box can be bolted to caving helmet, and / or fixed with cable ties or shock cord dependant on preference, the box having location channels to neatly accommodate the latter.

* Note - the Nora 2xs box has slightly reduced internal space versus the 3xs battery box. While it will readily accommodate 6.8Ah battery packs manufactured from 18650b cells, our stock of these packs is a tight fit in box, due to cable routing on the side of the packs. We will no doubt address this the next time we order 6.8Ah packs, but in the meantime the Nora 2xs box is only available with our 5.2Ah packs (and our 18650 cell holder). It is not currently available with our 6.8Ah packs.

 

If using 18650 battery holder it is necessary to carefully orientate red rc connectors at bottom of battery box, beneath the holder. If using 18650 holder with an original Nora 2 lamp set it will probably be necessary to adjust cable within the cable gland on the battery box in order to ensure that the grey sheath of the cable is not visible inside of battery box. This is necessary in order to provide sufficient internal space for battery holder.
