Poll..Deans or Gold Plug connectors for you batts

[BrianG]

Usually, Deans or Traxxas connectors are the top choices. Some like the Anderson PowerPoles too. All of these are keyed and protected. By keyed, I mean it can be plugged in only one way to prevent reverse polarity. By protected, I mean that the contacts are insulated to prevent accidental shorting on any metal. The downside to these connectors is that they are only rated to around 50A, burst is a bit higher.

The larger bullet connectors can handle higher current, but due to their design, they aren't keyed. Someone could accidentally reverse the polarity and blow something. You can put a male and female connector on the battery as a form of keying, but then one contact isn't protected and increases the risk of accidental shorting.

What would be really nice, is some sort of plastic plug add-on that would allow 5.5-6mm bullets to snap in to provide the advantages of both types of connectors.

I use deans on all of my RC stuff. The motorcycle packs get 6.5mm deans, but I have adapters for both the ESC and batteries so that I can use them with deans too. Works well, and makes putting packs in series a breeze. Positive is female on battery, and Negative is male. I use shrink wrap to keep them close together so there is less chance of short. Insulated male sides could be used to keep the positive terminal encased for storage.
