This is a panel mount AA battery holder.
I've been searching for a similar panel mount 18650 battery holder, but haven't been able to find one.
Does anyone know where I might obtain such a thing?
All the 18650 holders I can find are open to the elements; either it's on the outside, exposing the battery to whatever else is in the bag around it, or it's on the inside, and the device has to be dismantled to change the battery.
