[Elecraft] K3 and Power Poles

I fly RC helicopters and use Power Poles on all of my connections. My motor draws 75A with spikes over 100A. The model experiences broad frequency vibration, direct exposure to heat, cold, and moisture. I've never had a failure of a connection, an inadvertent disconnection, or wore one out.

Now to be fair I buy Anderson brand and use their crimper. 

If you are having issues with pp then my first question is where you obtained them and how are you attaching.

The only odd thing I do is coat them with Vaseline ( which I'm told is bad). After almost 10 years I figure I'm due for a failure or such.
