Battery connector 600amp

How is it to use these connectors on a 600amp burst battery pack?

I do have anderson SB350 to connect two cables together. But for single attatchements. How are these connectors?
Will they handle 600amp bursts for 10sec?

Or you guys got any other opts?

I use Andersons for big stuff, or Amphenol HVSL conenctors for high end applications. But with 50 mm2 cable that's not unreasonable.

And 600 amps calls for at least 95 mm2 cables. And even then, that's for a 5 second burst.

Seems to me you are in the territory for big contactors, or big bolt terminals.

However, there are some big andersons, and multiple sets could carry a lot of amps each.

Im making gokart. So it should be said i dont push 600amp all the time, its burst only.
I know people used 35mm2 cables on 600amp gokarts.
But the connector i showed, its brass, how is that compared to copper?
Wont it be enough?

Got any affordable other options, if this aint good enough?

The reason i want these single connector instead of the double is that im connectinf multiple packs in series.

Hey

I analyzed my 8 lap race and average battery current was 125A, event max was over 600A.
I'm using anderson 350 connector and 35mm2 cables and both are just fine with that. Anderson is 350A continious.
Here is graph also.

While there is no substitute for dedicated high power connectors, I wonder about the effectiveness of the bolt in the terminal fixing used in welder connectors. Some of the welder connectors have a copper crush tube under the bolt; others rely on the bolt compressing against the wire strands, a crimp connection would be better suited to high vibration environments and outdoor applications.
