Needle in a haystack if you ask me.

The only place that I can think of that might stock this is http://www.greenhobbymodel.com.

And online obviously, eBay and Hobby King comes to mind.

I assume you mean these?

(There is still another type that looks like a small version of the Tamiya connector, but that is white, box-like in appearance, with 1.5mm steel pins not 3.5mm gold plated. It would be good for about 15 amps I guess.)

Assuming the one shown above is what you have in your model, then these are called 3.5mm banana connectors. They are good for up to 60 amps.
The EC3 name is used when the 3.5mm bananas have been pushed into an optional added outer plastic surround part. The blue plastic bits are merely twin tubes that you are supposed to push the connector into after soldering it onto the wire.
eg thread wire through plastic tube, flux banana connector, tin, solder to wire, pull wire drawing connector into plastic tube.

Many of us use bananas for our electric models, but we avoid the plastic parts necause they make the thing overly bulky, and also for want of a better description, the plastic "frays" under use, leading to cracks after a while.
A far better way, and I suggest you try this, is to stick with the same inside metal parts, but simply slip a heatshrink on and heat to cover with a match or lighter.


Green Hobby would have those alright, the metal parts, but I doubt they would ever get asked for the plastic bits.
I saw some of those plastic outer tubes in 4mm size in Green Hobby about 3 years ago, but I'm sure they lay there long enough to rot with nobody wanting them, the plastic parts I mean, and everyone using heatshrink over their banana connectors.

There is a soldering tutorial Soldering Battery Cable Tutorial showing the common way of using those connectors (1 male + 1 female each side), but many modellers who got started with the plastic parts use the two male - to- two female arrangement as I showed here. You will notice how much neater the heatshrink makes it.

Hope this helps.

I prefer the bullet connectors used with the plastic fittings when using on lipo battery connectors. On ESC`s i just use the bullets with heat shrink. On a connector thats plugged in and out a lot i think its better with the full plastic setup. I could be alone in that though. The connectors are better held together in the plastic housings as well when plugged in.
