Male dean/Tamiya connector on the battery?

In case anyone thinks it's not worth it because of price.... That $7 will cover putting deans on every gun/battery you have, unless you really have a LOT. And even if there isn't a huge performance increase, the ease of use alone should be a good reason. I only use lipo's, and when I use a gun with tamiya connectors they get really hot, and even with a 9.6v 5000mah battery they heated up a lot....

Maybe it isn't that there is ease of use, and it is not the issue of there is not a noticable performance increase, it's that people are claiming there is with no substantial evidence to back themselves up. Evidence FTW

For those who are not willing to press the link, it states the following:
Deans-UltraPlug
-Contact Resistance female / male = <0.3 mOhm
-Continuous Current = 60A / 75A

Tamiya
-Contact Resistance female / male = <1.5 mOhm
-Continuous Current = 15A / 25A
There's a difference between a person who has a screwdriver and a person who knows what they are doing.

Deans are only effective on high amp situations only, airsoft guns simple don't draw enough power from the battery at one time to justify a deans. Putting them in an RC plane or truck is a no brainer because you can't stop the motor. If i get a high speed gun (25rpm+) and I plan on running the motor indefinitely, I'll go to deans.

If you are ripping the leads out of the tamiya you need to either calm the eff down or learn to install them properly. If you are using a good wire with thick insulation and you crimp it around the wire and into the insulation, its very hard to pull them off

Thank you guys!
I am going to buy the electrical wire from true value & have my friend solder it for me, since I don't have a soldering iron at home.
I guess I just use the male dean plug on the gun since I do have 3 pairs of deans at home. Since I am using an external battery case, I just worry the plugs will disconnected if I bump into something.
The mechbox of the gun is totally stock (dboys brand), and I use a GnP M120 motor with it. I did test it with a 9.6V 3300mah battery, it does give high ROF & respond pretty instant with the dean connector (the mechbox has no fuse).

Last question is, how to solder the dean on the wire? wire from the hardware store don't come with clips or clamps to clip on the the dean. Do I just stick the wire into the slots (dean), and solder from there??

Thanks again!

You have it backwards. You solder the wire to the metal tab sticking out on the female deans, and onto the shorter tabs on the male deans. Just plug them together then put the wires on the exposed tabs, really.

Gotta love the Metric system.

Like I said, you still won't notice a difference in performance between .0003 and .0015 Ohm. Resistance only comes into play at PEAK amperage (in respect to performance of an AEG). We're talking fractions of fractions of a second quicker response of the first shot on auto. If that's going to be the deciding factor between hitting someone and not, you need to take better aim anyway.

I'll be home in 4 days, I'll get some real numbers for shits. Although, they probably won't be accurate because I don't have Kelvin probes, but for a comparison between the two it should be adequate enough.

With those numbers you listed above though.

Ohm's Law wrote:V = IR

V = Difference in Volts
I = Current in Amps
R = Resistance in Ohms


At 20A:
Tamiya: 20 x .0015 = <0.03V lost
Deans: 20 x .0003 = <0.006V lost

Our batteries fluctuate voltage at much higher rates during use anyway.

You won't notice shit. There have been plenty of advantages for Deans listed in this thread. Replica performance simply isn't one of them and there is no necessity to switch.

Actually I am not switching from tamiya to deans, nor deans fr tamiya. I just need a quick fix on the gun battery supply source.
I have 3 pairs of deans at home ( extra stuff fr the GnP guns that I have), and I pretty much just need the wire & connector to be solder on & have enough length to reaches the PEQ box on the URX(SR-16) unit.
My second concern would be the battery itselfs. Do I have enough roon in the PEQ box to store a Nimh battery, or have to buy a peq15 lipo battery?
Very simple & straight forward, not much mathmatics involved, since this is my second DIY aeg since 08.

What PEQ do you have? There are batteries with all three chemistries that can fit into PEQs.

I have the VFC AN/PEQ15 battery box.
I know they make the lipo battery for that, but I try to save some $$ not to buy the lipo balancer.
I probably will buy one from cheapbatterypack.com if I have the correct configuration.

Hrm, I am fairly certain you're going to need lipos with the 15s.

I guess I have to buy that lipo and then solder with dean again ^^; I don't know if the gearbox is lipo ready or not~~
Wonder if the thinner 7V lipo will fit in the peq15?

All guns are lipo ready. And an 11.1v fits, so why wouldn't the 7.4v?

I guess 11.1V will work then.
True value doesn't has that type of wire, maybe radio shack?

Does JB weld works?
