Default Question on big, higher amp ESCs

Hello All,
New to this forum so please bear with me if this question has already been asked.

I am making a setup where I will need atleast 350A at 12s voltage.
i was looking for the esc options and came across a few of these-

1. 400A ESC CAR 12S LiPo R-Snake

2. Flier esc controller 22s 400A


Now both of these have 2 sets of positive and negative wire for the battery(2 red and 2 black wires)

I have 2 batteries 6s each.

How should I wire these with the ESC using both set of the wires.

Thanks.

I can wire the batteries in series to make a 12s out of 2x6s batteries but the question is why there are 2 sets of battery wires(2 positive red and 2 negative black) on some higher ESC's.
I can't attach the pictures yet, but you can search 400A ESC R-Snake.

Thanks.

I'm not familiar with that ESC, do they have an instruction manual posted anywhere?

I wonder if they bridge the cells for you internally?

I did find some info over here, maybe one these guys might be able to give you some more insight on it:

No.They don't have any instruction manual.

I also think it's just extra wires to connect batteries in parallel, to give you high amperage capability.
Basically two wires rather than one thicker wire.

Still, i will need more info to before connecting anything to it.

Thanks.
