Deans and Anderson power pole test to failure


"The load was a 16 volt lead acid battery through a carbon pile battery tester. The battery tester is capable of 500 amps for short bursts. Unfortunatly it was hard to regulate a constant amp draw. But I tried to start off at 50 amps work up to 150-200 with 300-350 amp bursts. then try and hold it at 350 amps or greater untill the connector or wire failed.

To summarize all 3 connectors, the deans, anderson 45 and anderson 75 were more then adequate for loads up to 200 amps."

Great video. Thanks! Nothing like hard facts to prove a point.

Use a good quality 4% silver solder it won't fail like that.

Now THAT was cool. One could argue a way to make the connection better for the Deans but not many would do it, this is a real world application and a weak point is just that. Hummm, never knew that. Time to finally switch out to APP's...

I did not hear it mentioned but, were the APPs soldered or crimped?
It appeared that the failure in the Deans was not the connector, but the method of connecting the wire.
Good test, thanks.

I came away from the video thinking that there was zero reason for me to swap from Deans. 120 amps is the peak for any of my aircraft and I'd previously waffled over whether to step up to a bigger connector. Now I don't have to worry about it!

The 45amp and 75amp equals constant 45 and 75 forever. Knowing this it's easy to know that you could get some time at 200 amps. I have a 24V carbon pile testor and have tested failure points of types of cells and chemistry. Combat robots have peaked at 1200 amps without connector failure.


thanks for sharing the very good video and data!

Good to see some real world testing - thank you for sharing.

Proves what many folks understand through experience: the solder will melt on Deans type *usually* before they fail due to the limited contact area, and APP/Sermos are industrial quality and tough as hell .

In my testing, the solder will melt on Deans with 10AWG at around 70-80A continuous (5+ minutes).

Would be interesting to see the same test with the silver solder that Reptileman suggested. It does have merit. I don't run more than 75 amps so I'm good to go.

I would be interested in seeing that test at higher voltage.

Though this test is excellent the one point that is easy to overlook is the test duration. While these tests may be useful in determining the "peak" current, they may not fully describe the tempature rise that during the full length of a flight.

Here is the thread were this video originated. There's another video with the testers comments about different connectors.

sweet! I really like my APP connectors.
