Like I said in my first post, I am getting back into this. But seriously how can there be so many connector types? Some batteries are "standard" but what from what I have read the definition of standard differs greatly! All I am trying to do is power my receiver on an old Nitro TC3!

I have no problem soldering but honestly are this many types of connectors really necessary? I was looking for a BEC adapter, then I learned that a BEC also might be the same as a JST? And then there is the Futaba J which I think is what I need. All I'm trying to do is convert the two wire BEC to the 3 wire of what I think is "standard?" Or is it?

What is the "standard" connection and what is "universal" connection that comes on batteries? Some have Tamiya and others replace everything with Deans and now my brain hurts. It the standard the three wire connector that only has two wires in it?

Connecting receiver batteries should be universal!

Deans is pretty much the universal now....

I use mini deans for all my rx/tx packs and regular deans for ep car/plane packs.

It's completely retarded. There are at least a half-dozen major battery connectors (for traction packs (7.2ish volt packs)) and it varies from country to country. If I had to take a guess I would say the old "Tamyia" plug is a standard for ground vehicles despite the fact that 80% of users cut if off and use something better. I use Ultra Deans, but they are not perfect, sometimes they oxidize/warp/wear out and they have a variable plugging force and can be difficult to plug in and unplug. Then Traxass [sic] had to throw a wrench in the works a few years ago with their new connector. It's a fine connector and all, but holy crap, not another one. And to boot their starter box wand thingie still uses a "Tamyia" type connector.

Somebody needs to form a "World Wide Commission to Unify these Dumb Connectors" group.

It's somewhat the same with "radio type" connectors, but there seems to be fewer options, thankfully. There is basically the newer Futaba ("J" I think) connector which has the little tab notch thingie on one corner of the plastic connector. And there is the "JR" type which is has chamfers (and on top of that there are at least two different size chamfers!) on it. You can trim either one to fit the other. I hate the JST deal, you can force one of these into a standard receiver, just make sure you have the negative and positive right, not a good system. And if you have an old Futaba G system I feel for ya, maybe this (without the bent pin) is what you want (and/or soldering skills with a does of X-acto wielding)?:



I usually just find the connectors I need and cut and solder the wires, just make sure you don't produce "hard-point" (which is basically impossible) in the wire that will fatigue and break with time and vibration. Use good shrink wrap/tape and make sure the connection is not allowed to flop around in the car.

Then there is the whole wiring deal, which I'm not entirely sure of. That may be from years past where Airtronics had some wires flipped around. Not to mention the whole positive/negative shift thing, oh don't get me started...

Somebody needs to be slapped.

What's wrong with choices?! I think it's great that there are multiple manufactures... I hope they come out with more, deans are getting a little old.. I've ran bullet connectors and that was so easy, unfortunately I no longer have a battery like that so I run deans..

IMO this is like saying why are there so many different kind cars? Can't we just make one and mass produce it. Now How boring would that be?

Options are your friend brotha... Just buy a decent soldering iron and you're set...

Deans are getting a little old??? They are just about the best way!

They offer the lowest resistance next to hard wire and bullets....

When you ask about a standard...
The connectors have been one general shape for the receiver since the death of "Futaba-G"

As far as receiver packs, that can be as subjective as any other battery pack.
Many guys use Micro Deans for their packs and as an on/off switch, reliable & efficient.
Servos today can also suck more juice than they used to.

If the pack you have has two wires & looks like it could plug into the receiver it will likely fit. just make sure the polarity & pins are lined up properly.

Thanks everyone for all the comments and guidance. I appreciate the patience while I figure this stuff out!

I think I get it - The problem is the switches on my cars have JST/BEC connectors and my battery packs have universal/Futaba J connectors. So like you all said I'm just going to cut off all the existing connectors and make everything Deans. Or I can convert the BEC plugs to Futaba J. I guess you just have to pick a connector type and go with it! That way no matter what I need to connect I can always have extra connectors on hand to solder on and make it fit!

dont get me wrong, I love deans... i choose them over anything else, but after they get a little worn and start becoming harder to pull apart... thats when i find myself pulling the wires because they are so small. If they made an extra long deans connector... then that would be the sh*t
