Thanks slawhammer forevernitro75 is hooking me up and I can't thank him enough. I have a ofna 1600 pack but I lost my connector I made so I have to use AA's till I make another one. To be safe I only run 2 tanks on the AA's and use them in my digital camera or in a clock. I have to build that connector again, cost to much with the AA's. Think when I take the kid to the park today I'm going to see if I can find the other piece of my broken cup.
