If you are anything like me, you hate wasting money and time with AA batteries in your flashes. You probably also hate the long recycle times that you experience while firing your battery powered flashes. Well, I feel your pain. So I have built a battery pack for my Vivitar flashes that allows me to pump some big power into my little flashes. I have seen several DIY battery packs on the net and when attempting one of my own I combined much of what I saw and liked into my own design.
