This battery pouch is made from a thick, waterproof canvas, protecting the batteries against spray water. It is not suitable for caving - the tough caving environment makes the aluminium battery box necessary. The cable of the caving lamp head can be fitted directly into it. For orienteering, a different lamp head with connector is used. Two different battery cables are available: A short one for wearing the battery pouch on the head and a longer one for putting it into a pocket or wearing at a belt.
