Sixth or seventh Anderson Power Pole failure this Summer...lost count

McKrakin,

Are these genuine APP's or are they a knockoff you picked up somewhere at a great price ??

Been there, done that and old enough to know better.....

I've had failures like that with APP. I think using them for ESC/battery connectors is just the wrong application for them. IMO, they are more suitable to connect components requiring less frequent connection/disconnection like car audio systems, etc. The hard plastic apparently can't tolerate many mechanical loading cycles before failure.

In ten years, I've never hard a plastic connector fail. I use them precisely for connecting batteries to ESCs because they are well designed for this application. The metal connectors take the spark on one surface and normal loads on another, so they are great for high current applications.

I read more obvious misinformation in this thread than I've ever seen before about Power Poles. It's weird about the debate between cheap, solder on connectors and high quality, crimp on connectors never ends.

I agree. I've never seen a PowerPoles fail, I've been using them for about 5 years and they have been flawless. My first Logo 600 had thousands of flights on it with the same PowerPoles on the Castle 80hv without a failure, when that ESC burned down I took the plastic housings off and put them on the new one. You guys are doing something wrong if you are having them fail. Hell, I've never even HEARD of a housing failing until now.

I know break fliud will break down some kinds of plastic, make it brittle and crack. Did you get any of that on your stuff? Maybe other cleaning agents will cause plastic to fail.

All of you who use these connectors......look closely at the corners where the tab part of the housing comes into the main body. Tell me if you see hairline cracks there. Look closely. A crack is a crack.

I used to use them on my RC buggies back in the 90's and found that the electric contact cleaner would cause them to become brittle and break the tabs off like this.

Ernie are you using any contact cleaner anywhere near the APP's?

Nope...No contact cleaner used anywhere.
I still think it's the CA glue.

CA will craze some plastics. But the APP housings are made of polycarbonate, and should not be affected by CA
If they are in fact molded polycarbonate then any kind of solvent will stress relieve them and they will just crumble apart. When we would have a PC part stick in a mold we would put tapping fluid on it, wait a couple of minutes and just flake the pieces out of the mold. If the part was big enough you could hear them cracking.
So if they have fuel residue on them, they will fail. If you have any kind of oil on them, like WD-40, bearing oil, anything. Some solvents will take longer than others.
One of the things that will make a molded PC part fail faster is sharp inside corners (like on the APP's), lots of stress.

4 years in the hobby, 40 years in molding.

Like I said...Anderson Power Poles

I actually have three different brands and at least one of every brand has failed the exact same way.
One of those is genuine Anderson Power Poles...which I believe has the most and fastest failure of all of them.

It's a nitro heli so there is definitely oil residue BUT the one on my charger broke the same way.

If the CA glue doesn't do it...what about the spray kicker I use to instantly cure the CA?

I checked over 100 real APP connector housings and not one shows sign of stress or cracking. Some of these have been around almost 20 years. Shrug.

I checked over a dozen of mine tonight, no cracks. Some of them have been used for three seasons on a 10s Logo. I also charge at 40 A.

I don't glue them, but I do use the Anderson keeper clips once connected. Perhaps this added securing reduces vibrations and stress.

Enjoy things that money can buy IF you don't lose the things money can't buy.

I dunno. Carey's comment has been my observation with the ones I have used. Not sure what makes some crack and others not, though I am suspicious of having unknowingly used knockoffs back when versus the real deal.

Dr. Ben, funny you mention possible imitation APP. I was very cautious with my supplier and willing to pay a premium to ensure they were genuine, especially after suffering unneeded pains with generic deans connectors. Maybe your plastics were different.

Switch to EC5 connectors and be done with it. Should of quit after failure #2

I checked mine last night, no cracks or breaks to be found. No intention of changing connectors, these are still the best I've owned. EC5s are not something I'd ever go back to, I'd have to find something else. Good thing I'm so happy with the App.

Yes the kicker will have an effect. Basically, anything but water!
If you have oil on your hands and touch them it will start to attack the plastic. So if you are working on your nitro and charging batteries you will get oil on the connectors. By the way, I promise not to use that in the next E vs N thread.
A lot has to do with the processing of the parts. Something the user has no control of. If when they are running the mold using mold release the parts will have some cracking right away. If you get a new part and it shows signs of cracking or stress whitening, it will fail eventually.
Best thing you can do is keep anything but water off a PC part.

Bents pins? Compare crimped to new ones prior to inserting into casings.
