Powerpoles on everything from RX packs up to 12s on my 7HV. Simple to assemble, reusable, solid crimp connection to the wire, and The oxidation from initial connection doesnt effect the mating surfaces once plugged together. It's the ideal connector in my experience. Used Deans, Traxxas, EC3, EC5, and nothing has worked as well as the APP.

The contact itself is good to 80-90a
I heard they were only good to 60A, but I've had a hard time finding anything solid about this on the web.

Gary, what are your repective HS's for the 600 and 700?

On the 600 (titan X50-E) I'm spinning 620's at a shade over 2200, and on the E720 I have three modes setup, 1600/1700/2000. 98% of the time is in the 1700 mode.It sounds strange to say it in this day and age, but that's my "3D" mode. Very smooth 3D, like in the 1990's, not crack style. That can be done in the 2000 mode, but it cuts flight time from 10+ minutes to roughly 6 and I like long flight times. I want to get it back down to 1600 for most of the flying, as the power is fine for my style, but I tend to stall the tail sometimes. Have some longer tailblades to try and if they work I'll be back up to 12-ish minutes at 1600.

back on topic regarding connectors. I did notice last weekend that I'm seeing a touch of pitting/wear on one terminal of the deans on one of my 720 raptors on the ESC plug. I will probably change it soon, but this ESC was originally installed in a 50CC plank conversion in 2006 (12S), and then in the Synergy conversion (12S) that I was working with a few years ago, then back in the 50CC yak untill just recently when I got this machine flying, so it's had a rather lengthy life so having to change it now doesn't bother me

Nice thing about power poles (also called Sermos) is that they are self cleaning everytime you connect/disconnect them.

I actually started with powerpoles when I got into e-power around 2000~2001 but only lasted a year or so with them before going to deans on everything. It seemed I was keeping the hobby shop in business buying tons of the little plastic covers as they were constantly cracking.

Cracking? I melted a couple on the connection between PS and Charger when I overdrew some amps, but I haven't cracked any of the dozens and dozens I've used.

I just bought a used Logo 600 w/ EC5 on the ESC and 4 pair of used packs... currently debating (w/ self) about changing them over to PP.

oops, bounced it!

Plus you can buy the metal contacts for 25 cents and easily replace them if they are worn.

I've heard that before, but have yet to see in my 25+ years of using these connectors on cars, and helis. I'm not saying its not happening, but I would like to better understand what is contributing to this. The plastic that is used on the APP housing is more brittle than the ECX plastic, or the Deans plastic. But in my models, I haven't noticed that the housing is under any stress.

Anything over 6S, EC5 period they work great. Also use them on motor and esc wires to.

...Once upon a time there were Nitros, flybars and frequency pins...

My only complaint w/ EC5, besides having standardized on PP, is that they're hard to separate, and I'm afraid I'll jostle the heli off the table or into something when I separate them. I'm getting better at technique, but I can do PP in one hand in an emergency, or while holding the removed canopy out of the dirt, etc.

oops, bounced it!

Hi all,
Very interesting thread with tonnes of info.

I am only using 2 x 2 cell lypos 2500 to connect to rx via the regulators 5.1.

Are deans connectors ok for this ? or would you recommend switching to these other types of connectors ?
The model is a large 1/5 scale longranger..

Can someone show a photo of the EC5 or Powerpoles as in my club most if not all tend to use deans.

thanks for help and apologies if this question takes it off topic slightly.

Matt

I would imagine EC5 would be hard if not impossible to remove easily. Just try prying the 4mm bullets off one at a time. EC5 makes it more than doubly hard as you have to removed both simultaneously.

That is one of the things that are sort of putting me off from converting to EC5. I considered just bullets. But, one carelessness is all you need for a quick bonfire.

4mm bullets are also impossible to fit 10gauge or thicker to fit in the tiny hole for soldering. I enlarged the hole with a drill few times to do the ESC but that gets tiring too. So on the picture above, I used the 5.5mm bullets not because it was needed for current but to handle the thick wire soldering. Knowing I'd be using Deans, no point of going big on certain parts unless you do it all the way around to eliminate the "weak link".

Something similar to EC5 with low insertion/extraction force will make me change.

We switched to EC5 connectors after crashing two machines due to the Deans connectors unplugging in flight.

Benny, they aren't hard to get apart. The plastic case makes it easy enough.

Aside from not coming apart in flight, another benefit is soldering the EC5. It is a pleasure compared to the Deans.

The amperage draw there is very minimal....Deans will work fine........Ron

I got this one down good.

As for the dean coming apart, tell Kyle to go easy on the heli
Did you secure one end of the dean or were both ends flopping in air?

The connectors should never pull apart in flight. Deans or not. Just means the connectors were going to fail...Ron

I do remember seeing these on early days of Trex600e when E flight was new. With the angled plastic battery tray that flexed, depending on how tight the connection was, under hard load, the battery flexing actually pulled the connector out and caused crashes.

Boy! That seemed like ages ago.

Same thing happened to me, but from EC5's I then switched to 6mm shrouded bullets, to decrease resitstance in the wiring to a min on the high powered systems.
