As a child we used to have a special plastic container in the fridge. The battery container. At any given moment it had a about two dozen batteries.
As I grew up and started to use a camera (a used Nikon F70) and a strobe (A used SB28), and then 5 strobes it was only natural come up with a better system.
A system that would be kind to mother earth on one hand, and will allow me to shoot as much as I want on the other. The system evolved over the years, and will probably keep changing. This is where I stand now.
