Deans connections
Hey guys i was wondering what was the difference between deans and regular wiring? Also if anybody can give a a rough estimate on how much would it be to remove or put on deans that would be helpful thanks.

Deans plugs replace the connectors between the airsoft gun and the battery. They offer a much lower resistance than the standard "Tamiya-style" connectors found on most airsoft batteries and chargers. I read somewhere that the deans connector actually has a lower resistance than the same length of 16 gauge wire, but that's probably just a marketing ploy.
Deans plugs might increase your rate of fire slightly, but won't increase battery life. If anything, you might get less play time out of a Deans setup because of the increased current flow.
If you really want them, it's probably something you could do yourself. You have to cut off the original battery and charger connectors and replace them with the Deans plugs, making sure you've got the positive and negative correct. It's a really simple soldering job and has been covered many times across the webernets. If you don't know how to solder, it's a great skill to learn.
You'd probably want to make an adapter for the charger though, because that connection isn't as critical as the one in your gun, and you'd want to keep your options open.
And as far as the price for someone doing it for you goes... that would depend on the number of batteries you have. Not sure if M A/N does re-wiring...

i have used deans for years on my R.C. cars. and they do help. i have read a artical in a rc mag years ago about deans having less resistance than the wire you use or the solder joints you put on them. i have to question that
also try to put aligator clips on your charger, and make deans and junk tamiya plug tails to attach on the gator clips. when you charge than you can charge your batts, and buddies batts if needed.
sorry to butt in but needed to get it out
oh yea make sure you use flux when soldering, don't count on flux in solder. also i suggest using a resin core solder holds better. don't use a high silver content solder can't explain why just don't. old dude in rc told me why but forget sorry
I'm calling complete and total bull**** on Dean's connectors for airsoft. I cannot see how under normal operating conditions that you will gain anything that would justify using them. Other than another reason to feel superior about yourself, they are next to worthless. At least untill someone shows me actual DATA from airsoft use saying otherwise. Forum posts from ASR are NOT data.
Just installing Deans does nothing. Just like installing a new nubbin without changing the bucking. If you want the supposed "advantage" of Dean's connectors, you should, at a MINIMUM, change all of your wiring too. Honestly, unless you are willing to run a matched set of batteries, change all of your wiring and possibly the motor, the connectors are a waste of time.
Just changing the connection to the battery in an M-14, stock out of the box, got an increase of 1 ball per second faster over the standard factory connector. So YES there is a difference, but if you want more of an increase, and a more reliable connection, change out your wiring and get a mosfet(which is not needed but wanted). These are all things I have done and I am testing them as we speak. I installed (with Mavericks help) a SW mosfet, with burst capability, motor control, and motor breaking, as well as a 11.1v lipo battery and Helical gears . A Mosfet upgrade will save your trigger plate and it will stop your motor on a dime. It also has quicker trigger response, and at 20 bps at 370 fps with a stock motor. Once I put my rig through a proper field test. I will post my findings....All I can say is, anything you can do to create a better flow of electricity to the motor as it is turned on and off will benefit you. Some benefits will be seen some won't, not without a volt meter and a close eye on you battery output......My two cents..

Nobody in airsoft says "ball" when referring to BBs.
What kind of M14? How many samples did you use in both halves of your test? Was the battery in the same state of charge for both tests? Was it the same battery? How much time elapsed between the first test and the second test?
I'm sure you are a nice guy, but I just don't see it. Anyone can have an opinion and a forum account, and you may think it made a difference, but I would like to see real proof. Proof which nobody has been able to supply. Ever. The opposite of "anecdotal" is still not "data."
If you ever have occasion to do it again, especially at Montgomeryville Army/Navy, I'd like to see your tests.
ETA: And you could gain a more significant increase by simply using a better battery.
I'm not saying that the connectors don't do anything measurable. I'm just saying that they should be the LAST thing you change, and they will not make a world of difference. Somehow every fourteen year old kid thinks that he needs these connectors to compete. That simply is not the case.
I have to agree with Lou and Bracket that Deans are somewhat overhyped, but I still think they're an upgrade over normal connectors. When using a fully charged 7.4v LiPo in my G36c, I noticed an increase of one or two rounds per second; a small improvement, but it's there. The other two things I like about them are that they're smaller than tamiya Connectors (I've had lots of problems with tamiya connectors being too big in the past), and they don't get worn out like tamiya connectors (after a while, the clamp that holds them together may break off from use; it's happened to me several times).
Actually recently we did do a test for one of our employees that purchased a brand new airsoft gun.
Gun: echo1 SOCOM m-14
Stock fps out of the box: 365-385fps
Stock BPS: 10
The only modification was the deans connections, the battery was not charged in between tests, thus it had less power that the initial test.
Deans connections BPS: 11
Tested with KSC .20g bb's, using a paintball red radar chronograph.
Conclusion: Deans connections do indeed help lower the resistance in the wiring harness of airsoft guns.
Lower resistance would mean more BPS. Shot count per battery was not tested thus no conclusion can be made in this case relating to shot count.

Thanks for posting that. It was most helpful.
Actually, Bracket and I are discussing a test using a bench power supply to see how much of an increase these connectors give over the tamiya connectors. The nerd in me loves data.

Please post the results. I am interested in knowing if the Deans I installed over the summer are doing something for me.
Don't hold your breath on that. I checked the equipment we got here, and it would be very difficult to measure the exact resistance of these things within any degree of accuracy. The solution I can think of would measure the current going through a controlled circuit with the different connectors, but even then, there might not be enough of a difference to rule out other experimental factors.
I'd have to buy two sets of the connectors, a bunch of high wattage resistors, write a microcontroller program to measure the current... make fancy graphs and crap...
And I couldn't test this on an AEG until I come home in May anyway.

Or, you could just test the RPS before and after the instillation of the connectors. That's probably what 80% of the people here really care about (no offense intended of course).

The two questions we're trying to answer here are "does it increase rate of fire?" and "does it increase battery life?" How do you plan on answering the second part?
If we can determine the difference in current draw in an AEG, we can unambiguously determine how long the battery will last based on its capacity.

I switched to deans because I came to Airsoft from the world of R.C., Because of that all of my batteries and chargers were already wired for deans. I'm not sure if they help as far as ROF, but one thing I have noticed is that you don't ever have to worry about a crimp comming undone and a pin pulling out in your battery, because the only 2 joints are soldered. Also, the chances of the plastic melting and causing a short is much less(I am not sure if this could happen with an airsoft gun, because the motors are smaller and have much less current draw).
In reality, all of the above is just a personal experience, and one case out of 1000.
I agree with MaverickMonk. The main reason why I switched to Deans is because Tamiya plugs provide a poor electrical connection, and aren't durable. They pop out of the plastic casing, the prongs get bent out of shape, they bend inside the plastic casing, and melt if something shorts out. If you need to replace the prongs you need to get a special crimping tool, which aren't cheap. Most people just crimp them with a needle nose which doesn't hold up. The wires can pop out of the prongs which would suck in the field.
I installed Deans onto my galil, and did notice a slightly higher rof. It isnt really anything to brag about, just maybe one or two more bbs per second. I mainly got them because there a better design. They are a more durable plug. Instead of tubular prongs, there rectangular plugs that slide against eachother. There spring tensioned eliminating the need for a locking mechanism (that can break off), and makes a better contact. There is no need for crimping because you just solder them on. The plugs offer a larger contact area as well. I also like them because there smaller, and make it easier to fit batteries in guns.
So for me I think its just a preference in terms of a better design, and ease of use. I would install them in high rof guns, or for those looking to enhance the durability of there aeg.

I can't detect any difference in performance with Dean's.....but maybe there is a slight improvement...I don;t know....
I do know that if you have a Deans gun and your battery dies, there ain't many dudes out there with a Deans battery to let you borrow....
AND....if you're battery connections are in a tight spot (SIG552, in the stock tube, etc.) it is a distinct possibility that the skimpy shrink wrap that goes on the solder point can get rubbed through easily causing a short and possible battery/switch/wiring/motor death, not to mention an electrical fire....
so for all these reasons, they are not worth the trouble to me.....
unfortunately, I do speak from experience.....

I just had an idea. I am taking a class at school called Energy, power, and transportation. We are learning how to read variable meters. One of the settings on the meter can read resistance in ohms up to numbers in the 100k range. I think that I might be able to test my battery with deans (9.6v) and my friend's with battery with Tamiya connectors (8.4v). If I am thinking about this correctly, the different battery voltage should not affect the reading, correct? Because all Tamiya connectors resist a certain amount of volts, and Deans connectors resist a certain amount of volts? Just let me know.

No. In this case, we need a multimeter that can read extremely low resistances, like, micro-ohms. And if you're testing the voltage of this battery, the voltage across the leads won't change at all between the two different connectors, because it's an open circuit.
Come back when you've taken "Energy, power and transportation 2".

Alrighty, that makes sense.

I mean to say that if I did have a multimeter that read micro-ohms, then the voltage of the battery should not affect the resistance the connector has, correct? For example: If I have Deans on a 9.6 battery and on a 8.4, then the resistance should be the same for the connectors, right?

If you jabbed a multimeter set to measure the resistance of a circuit into the terminals of a battery, you would more than likely damage the multimeter. It reads resistance by applying a voltage to the terminals and measuring the current. It's essentially a small open circuit. The battery would be applying voltage of it's own, and would damage the multimeter. (Though they often have built in fail safes)
And yes, the battery WOULD have a drastic effect on any measurement you try to obtain. You would have to design an experiment that isolates the connectors from the rest of the system as the only experimental factor.
