If you're going w/ RC connectors, I probably have some Tamiya Connectors you can have...  http://www.google.com/products/catalog?hl=en&rlz=1G1GGLQ_ENUS249&q=TAMIYA+CONNECTOR&um=1&ie=UTF-8&tbm=shop&cid=5737493381706344421&sa=X&ei=LVpeT6S4FYSYiQL7gK3bBA&ved=0CGsQ8gIwBA#

If not, they are dirt cheap at Rat Shack...

Thanks for the offer Terry. But, I'm a bit leery of the Molex type connectors for repeated connecting and dis-connecting.
I'm going to buy some of the 3.5mm HXTs after work tonight and try them. I've been reading up. They are built for repeated use and are used by a lot of the RC guys. It won't cost me much to try them either.

Hmm...  Those looks like connectors I tried years ago with my car stereo...  They work great for a while, but eventually the plastic sheath came off of the pin...  As for the Tamiya, I always hated them b/c I thought they were a bitch to pull apart.

Let me know what you find, I've got a possible project in mind, and I'm looking for locking power connectors...  melikes the 4pin hirose and the 4pin mini-xlr right now...

So, I bought some HXT's and tried them. They are easy to work with and inexpensive, but I found that some of the wires I am working with are too thin. When filling up the solder cup on the HXT's, the wire wicks up some solder and makes the transition between the solder and the wire very brittle. I noticed that with just a few wiggles, the wire snaps off of the connector.

Since I really like the connectors, I'm going to try just soldering the very bottom of the connector to the wire and filling the rest of the solder cup with silicon to act as strain relief. Also, If I don't fill the solder cup with solder the wire won't wick it up all the way to the top of the solder cup. Hopefully that'll make the wire less brittle at the junction. I'll also try two applications of heat shrink on the wire the next time.

Those HXT power connectors like like or very similar to the battery power connectors used inside computer Back UPS which would use a larger wire, but they appear to be solid connectors.  Thanks for the progress update.

i use the tamaiya 'cos that is what comes attached to the batteries i use. but they can, as said above, be difficult to pull apart. but once you get used to handling them, they are fine (they rotate). but the connection is secure, and the connectors are crimped not soldered, which might be a bonus for you...

Here is another option.  These power connector used for bicycle lights so they are both locking and waterproof.  The lock is very secure.  It is the common size 5.5 x 2.1mm barrel with an o-ring lock and seal, so it will connect to a non-locking 5.5 x 2.1mm barrel also.

The above link shows both the male and female version of the connector.  These connectors are also available attached to a non coiled cord.

I've used this connector for both my bicycle and audio gear for a few years now without a problem.

Those look OK, except the connectors are permanently attached the wires. I need bare connectors that I can solder myself.

If I was going to splice wires, I'd go with these. http://taperssection.com/index.php?action=dlattach;topic=154149.0;attach=106407;image

Which are starting to look really good to me now. They have nice beefy wire and a nice tight fit. I'd have to figure out a good way to splice into them though.

Those look like a 2 wire version of the 4 wire connectors that are commonly used for trailer lights. Perhaps a visit to your local RV/boat/U-Haul dealer is in order if you need more than two wires.

Well, I decided to go back to the RCA connectors I've been using. They provide a rock solid connection, are cheap and easy to source and are very easy to work with.

I do have a few of the HXT connectors left (6). I'd be happy to send them to some of you if you want to check them out. I'll put them in a bubble mailer and send them USPS for free. Please PM me with your address if you want a couple to check out. I really don't have many, so only PM if you think you really might be able to use them. I'll let you know if/when they are all gone.

I'm a bit leery of whether they can be repeatedly connected and dis-connected.
fwiw, the tamaiya connectors work time after time. the crimp is inside the plastic - the only issue is that the plastic has to be rotated the right way to make the connection work; this is a feel thing, and once you figure it out, it ceases to be an issue.

Thanks for the heads up. I'll pick some of those up to try. The ones I got from Radio Shack don't really lock. I just needed to assemble my battery system again so I can use it over the weekend.
I probably won't switch everything back until I exhaust all the options.
