Anderson connector for quick disconnect?

I am planning on bringing 24v to my Morningstar MPPT 60 but have an Anderson connector as a quick disconnect close to the charger. Would this connector cause too much resistance or be a poor choice for other reasons?

Deans have an average resistance of 525u-ohm (micro ohm) which is .000525 ohms. So using E=I*R, Assuming 60 Amps your looking at (60*.000525=0.0315wats) 315miliwatts of loss.

Anderson Powerpoles have 600u-ohms. I think your safe!

I like powerpoles as they are easy to work with and you can solder the ends on with a pencil torch (no iron required like deans). I use them on a 50W panel & a 4000W electric bicycle) but they can wiggle vibrate loose under heavy vibration so keep that in mind (Strip of Electrical to be sure it stays).
I use deans on my model planes and helli's where a loose connection can cost me 1000's...

I like to secure my Andersons together (mated that is) with a small zip tie.
Easy to cut to remove, non-metallic, inexpensive and for me, held together on the back of a motorcycle ride from upstate NY to FL and back...

Good point! And will definately hold better than electrical tape

What I have found with Anderson connections is sometimes the connection point is bent on initial installation / wire insertion. You'll know this is happening if you can pull them apart with zero effort (almost falls out).
I have found that putting the connetor down on a flat surface and pressing down firmly or even giving the end a good pinch straightens the contact point and you get a nice solid "SNAP" when you put them together.
