I really don't understand why power connectors aren't just + and - anymore. There's no reason for more than 2 connectors. What is this 12-pin Molex bullshit? Why the hell would you need 12 pins? Use some Anderson PowerPole connectors, XT30/60/90, or some other connector designed to handle high currents.
