I can only help you with the Zmax board with the hand-drawing. It's backwards. The black wire is the ground or negative which should go to the outside or "-" of your atty connector, the white is the positive that should go to the center post or "+" of your atty connector. If you're not using a metal mod body as a ground for the battery and atty connector, you will need to run another wire from the black wire to the negative end of your battery, similar to your picture. The round "+" ring at the other end of the board from the wires goes to the "+" end of your battery.
