Okay, I am going to request an article, one that I hope I can find out about here.
What are Deans Connectors, why are they preferred over the Tamiya ones, how do I install them, and where can I buy them?
Here is a picture so you can get a feel for them.

The wires go one the short metal side, the long male and the female side bet plugged together. They are better than standard Tamiya's because they have more metal surface making contact, which allows for greater electric flow. To install them, you have to cut off your old connectors, strip 1-2mm of wire on the end of the wire, make sure your +/- sides are aligned with the correct wire, and solder away. Lrasdeadman has a really good youtube tutorial on the soldering part of it. Modify makes some - ASGI sells them. $5/pair
