i personally don't like the deans, or should i say the way most people set them up. Usually, most setup the wiring using a sorta Y-harness thing. Then that leads to one deans plug per battery. This setup works great, but if you use a schulze esc or you want maximum performance, you should go with a different setup that shortens the wiring. This insures maximum performance, neatness, power, speed, and efficiency. And is basically the only way to qualify for schulzes esc warrenty when useing side by side packs.
So, this is the kinda setup i would use

I use 4mm gold connectors as connectors, they wear out over about 2 months, but they are more conductive than the deans i believe.
I love the setup, and when charging i just use the alligator clips.
