Hi, can someone answer this question please? I purchased a used Slow Stick and it has a Dean (I believe) connector. My Thunder battery has a connector as shown in the pic.

Can someone please tell me what connector I need and where to get it? Thanks!!

Umm... a female Dean's? You'll find that you have to choose a standard connector for yourself, and convert just about everything you buy to that standard, be it Dean's, XT60, whatever. Just choose one, get plenty of spares, and learn to solder them.

You might be able to find that at your LHS. If it were me i would solder new connectors on. Micro on your plane to match the battery. Or, full size deans on your battery. You might want to think about future planes and keep a common plug......

As rrg says, this is a job for your local hobby store. If you don't have one locally, here's the simplest solution from a reliable vendor that will ship to you VERY quickly for $2 shipping. (I'm sure you're anxious to get that new plane in the air).

Of course, the more "elegant" solution is to actually solder the plug you need onto your battery or plane, so you won't need the adapter with its extra weight and unnecessarily long wire. HeadsUp carries those too.

Your little battery plug is JST, meant for low amperage setups on lightweight "micro" planes. Your ESC plug is a Dean's connector, the most commonly used connector of them all, but needless weight on planes under 8-12 oz.

There are several threads you can search on this site about "favorite" or "best" connectors. It's true that you want to chose one style and commit to it, so that you won't need a bunch of fussy adapters or multiple setups for different planes. Personally, I hate soldering, so I've been very happy with Anderson Power Pole connectors (AKA Sermos). These can be soldered, but you want to invest in the crimper which allows you to quickly install these connectors on anything without soldering. They can be modified (trim off the back end) to save weight when needed. The other reason I like them is that they are MUCH easier to connect and disconnect than Dean's, especially in tight quarters (most battery compartments are cramped) and ESPECIALLY if you have arthritis. Dean's can be quite stubborn, and when you muscle them apart, it's very easy to damage your plane. People modify them to get a better grip. I hate Deans. Even if you solder the Andersons to save $40 on the crimper, they're easier to solder than Deans. For micro/indoor flyer stuff, you'll want the JST's.

Either invest $50 here: http://www.powerwerx.com/anderson-po...pole-sets.html
on some Anderson Power Poles and the crimper OR invest your future time and frustration in Dean's or JST's or EC3's or others.

Excellent. Thanks all. So, the adapter you link below calls one side "T-Plug" ... that's the same as a Dean?

BTW, here's a safety tip:

Whenever changing or installing connectors on a battery, ALWAYS do one wire at a time.

Do not clip both wires at the same time (your cutting tool will short out the battery, possibly dangerously and surely to the detriment of your battery's health). Keep one wire insulated while you're working on the other one. Finish up that side, get your connection insulated with heat shrink and "capped" somehow, then do the other side. (Another advantage of Anderson connectors is that once you crimp the metal bit on to the wire, and snap it into the red or black housing, it's safe from accidental shorts).

Yup, generic Chinese ripoff version probably. I think your plane's plug is actually a generic T plug rather than a Deans branded plug, but I'm a little color blind so can't be sure. All the T style plugs available are compatible, except I believe there is a "mini T plug" available. Yours is the standard size.

I've been using these T connectors from HK for yrs with no problems. If you find them too tight, flatten the spring. Not a big deal. The XT60 connectors from HK work very well too.

Gord.

Agreed... go ahead and convert everything you have to one style of connector now. I use Anderson Power Poles for everything but the smallest stuff and for that I use JST connectors. It will make your life much easier as your collection grows.

Can we assume you mean the PP15-45 Anderson connectors? Without trimming, those are a bit large, but you can trim them down to just over 20mm length, if needed, I guess.

Looking at the data sheets, there are hook-like features on the ends of the contacts - I suppose to resist separation. Those hooks don't make them harder to separate?

That's correct. I've been using APPs since the mid-80's when I raced R/C cars and trucks and I've never had a failure of these connectors. The hooks make a good positive connection and they are advertised as "self-cleaning". They are not hard to separate, but of course they won't hold the weight of a battery should it come loose in flight (ask me how I know).

If you go to these connectors, I highly, highly recommend investing in a crimp tool.

I might as well add the XT-60 hooded connectors. Gold plating does make soldering the wires very easy.

I recently converted all batteries & ESCs to them. They pull apart easily. If you couple a dummy male or female to each other during soldering they will keep perfect alingment when you finish soldering.
I no longer use heatshrink tubing on any exposed connectors. To darn hard to fit correctly............Good black plastic electric tape is far easier & better.
