Dean connectors

[donkeykong]

So what are the main benifits of the dean connectors, I searched this and all I could find was people saying switch but not reasons why. They are low resistant so I am guessing you are going to loose less power over the connector meaning longer run times, but will it be significant enough to notice. Also if I switch the evx plugs I can kiss my warranty good by right. So I guess I am trying to convince my self that it is actually worth it. So whatever plus's there are post them up please. And where are the best places to pick them up. I know I can get them from my LHS but if I can get a handful online cheaper than I will

Deans are way more reliable and don't heat up and burn like the tamyya style.i buy mine at tower if i'm ordering other stuf.if not there my lhs.price isn't much diff.i use the micro 4 pin which was the orig "the plug to use" back in the day.not worth it for me to change over.these lasted me for decades with no problem.and about 1/2 the cost the the ultra's

RESISTANCE IS FUTILE

How much better are zero-loss connectors than Tamiya-style plugs?
Below is the measured electrical resistance of Deans, PowerPole and the old standby Tamiya connectors.

• Tamiya type: 0.0033 ohm

• Deans Ultra plug: 0.0009 ohm

• PowerPole: 0.001 ohm

• AstroFlight: 0.0011 ohm

What does it all mean? By switching to zero-loss connectors, you'll send more power to the ESC and motor and waste less on heating connectors. The numbers become even more telling when you factor in wear; after hours of use and many plug/unplug cycles, Deans, AstroFlight and Powerpole connectors lose little efficiency, whereas Tamiya plugs lose their grip and develop even more resistance.

Assuming a 40 Amp draw on the Batteries.
To calculate the Voltage Drop Loss over the connectors:

V= I X R = (40 Amps) X (.0033 Ohms) = .132 Voltage drop for Tamiya connectors
V= I X R = (40 Amps) X (.0009 Ohms) = .036 Voltage drop for Deans Ultra Plug connectors


Expressed in Watts,

P = I*I*R = (40 Amps) X (40 Amps) X (.0033 Ohms) = 5.28 Watts loss for Tamiya connectors
P = I*I*R = (40 Amps) X (40 Amps) X (.0009 Ohms) = 1.44 Watts loss for Deans Ultra Plug connectors

Dammit Jim I'm not an electrical engineer!!

That was good learnin'!

You can always re-install Tamiya type plugs if a warranty issue arrises. It is WELL worth it to install the deans or power poles. I have seen the tamiya plugs get so hot that they melted the plastic portion of the connectors together. They are JUNK! If you are set on running the tamiya connectors, check the female ends and make sure they are not "spreading out", if they do just bend them back into shape.

i once soldered the connectors the wrong way and two batteries started sending power dierctly the wire was smoking but the connector was stil cool enough to pull apart :shock:
