Battery Box Features
We have had a number of requests to buy just the Nora Battery Box, presumably for self build lamps, etc. We are going to have some more Nora boxes manufactured shortly, and we will get some extras. If you asked before, then please feel free to contact us again.
Robust, lightweight, versatile design
Battery packs can be removed, exchanged (and replaced, batteries don't last forever)
Battery pack / lamp connections internal to box (no external connectors)
Range of useful proprietory battery configurations (low cost replacement, again batteries don't last forever)
Proprietry low voltage Li-ion packs, 3.7v.
NiMh / Alkaline compatible in a practical form (3 x AA batteries)
Recesses for flexible helmet fixing with cable ties / shock cord. No rigid helmet fixing screws.
Thick wall construction to best (hopefully) avoid distortion (and leakage) at depth / pressure
Machined from solid Delrin to realise light weight with thick sections.
Better, more attractive wear resitance than thin section aluminium boxes (box invariably takes a kicking and anodise comes off).
No irritating metallic clunk clunking on cave roof.
Stainless steel toggle clasps and big section O ring to achieve and maintain water tight seal (essential for Li-ion battery packs). Can be locked by the paranoid.
Easily serviced design.
Lid connected with 40Kg Kevlar braid to avoid losing. Robust, light weight caver solution.
Externally seating thick section lid designed to take wear and tear burden, and avoid (expensive) damage to top edge of box, and innevitable leaking (characteristic of inset lid arrangements).
Low cost replacement lids if necessary.
Waterproof cable gland.
Compatible with most helmets, even the Petzl Elios (in childrens size)
Diveable, we shall see. (Dive testing is ongoing, nothing bad to report yet)
