Dear Modelers,
I hope that my email will find you all in good health.I would like your advise concerning electric connectors.I have been flying small electric airplanes for the last 15 years,using power pole(sermos) without any problem.Because I would like to move to bigger electric airplanes,my sermos are not suitable anymore,because I will be playing between 60 and 80 amps.
I did search in the internet,and yesterday I had the opportunity to touch (my friends airplane)the supra X, golden connectors(pro x4 dc p3, rated at 120 amps peak,and 80 amps continue)They look verry nice,build quality looks great,and when they lock ,you feel a klik.
Anyone having used these connectors before?Are they reliable?Thanking you in advance,I hope to hear from you soon.
Merry christmas,and a happy new year to all of you,always with happy landings!!!!

The 30A and 45A power poles are fine for large electrics. They are rated 30A at something like 600V, so they are certainly made for high power connections (600V x 30A = 18,000W). If you look at things like the high power safety switches, they are often made using power poles, like this:

I personally fly 10S aerobatic planes and use the 30A and 45A power poles. I have been running them up to 80A (40V x 80A = 3,200W) with no troubles and expect to be running them even higher in my next (bigger) airplane. Lots of us use them and I have not heard of many, if any problems.

Hi there from Toledo

I have used Anderson Power Poles since 1989 on packs from 2s to 10s Lixx cells, 6s to 24s NiCad/nimh packs, and ESCs from 25A to 100A.

I have never had a failure with APP products.

I use the APP for the pack and ESC connections. I use bullet connectors between the ESC and the outrunner or inrunner motor.

My charger has adaptors from banana plugs to APP and other brands too for helping newbies at our club training days.

I don't know the connector you asked about. I am standardized on Deans Ultra connectors.

I understand that Deans are rated for 50 amps continuous and 70 amps burst. However I read there are people using them in 100 amp burst (30 seconds) configurations without issue.

Here is a 5500 mah 60C pack shown with a Deans on it. T
that pack is rated for 330A continuous, 440A burst

You may know all this but, FWIW, the standard approach is to increase voltage rather than current In order to achieve the wattage you want to hit.

I don't know what wattage you are targeting but you said you would be running between 60 and 80 amps. Could you go to a higher voltage and drop the amperage? Remember higher amperage also means bigger where higher voltage does not. Just keep that in mind. Higher voltage and lower kV ratings on the motor are a better path than higher amperage, assuming you have a choice.

A 12 Cell Lipo pack, 44.4 volts nominal, at 60 amps = 2.66 KW or about 3.6 horsepower. That's 100 watts/pound on a 26 pound plane.

This may all be obvious to you but just in case it was not.
