If analog inputs are reversed, or swapped what does it do?
Does each work individually on its own?

Next problem! So I bought this cheap contactor off ebay
And when I apply 14v to the small silver contacts the main contacts do not close (I've tried in my circuit and with a 12v battery and a multimeter on the bench)
So it's faulty isn't it?
It seems obviously faulty to me but I've been wrong before so I'm just looking for confirmation please!

This is a very steep learning curve I'm on, but I'm undaunted, I'm making progress slowly and that mistake only cost £13
I just tried it at 48v. Guess what? It works.

Do you think the main contact will be ok at 48v then? I tought the main contacter was rated for 48v, not the coil. I could still use it if it will cope.

Thanks to woody for original pic
So for 12v read 3.2v and rather than two cells there would be 8 LifePO4s, so a bank of 8 andersons.
And charge at 3.5 - 3.6v? So no need for any ballancing.
And then remove the 8 andersons in your charging loom and plug in the anderson jumpers as in the pic only there would be four, not one to plug in probably use 8awg silicon.

Board design is a bit tricky (3-layer with vias in pad and lots of heat sink area needed) and input can't be > 15V, so at 12 V you'd need near 70Amps for the 800 Watts total output. Everyone seems to have these, and RS has a much lower price (but is evidently discontinuing it as it's only "until supply exhausted").
