Argo FET for 2 alternators, 3 batteries

Replacing an old diode battery isolator here. The original was simple, with two inputs and 3 outputs.

Argo does not have a FET isolator with two inputs.

I was suggested to use two Argofet 100-3, and connect the outputs in parallel. I created a simple schematic of my understanding. Can someone with expertise on those boys to chime in?

Hi jetkit, same here :)

Picture is from last weekend. Note there are inputs from alternators and some other wires missing.

I was assuming it will work and had found confirmation on a YT channel PYS.

Will have first hand info in two weeks when I'll do the test.

I have some other concerns regarding return voltage to INPUT in this state (picture) but I don't want to highjack this thread.

Tested last weekend and sure it works.

Not that I did extensive testing because my batteries were fully charged.

I didn't measure current passed to each battery bank but voltage was present and there was no voltage drop across input/output terminals.
