The Petzl Duo runs on 4 AA batteries. To carry four spare AA batteries (essential) I have found the little box at:

very useful. It goes in the oversuit or undersuit pocket, is alluminium so pretty tough. Not waterproof though but that hardly matters. An elastic band is a good idea to keep it shut if the press button is pushed by accident.
It's meant for carrying credit cards. Just rip out and chuck away the plastic card holder, get a bit of bubble wrap, or whatever, to stop the batteries moving about. Just thought that the padding could be first aid bits rather than bubble wrap.
Another though while writing is that a large cigar tube (it would need to be 21cm long) snoopied to the helmet migh t be even better.
