DC-DC Chargers in Parallel

Yes, I agree the lynx is huge. So, I have seen on a shematic from Victron where you only run the postive wires to the busbar and the negatives are only linked together from start battery. Can I ask are you running one pos and one negative from the starter battery and them linking them together and also what size wiring are you using?

I think you may be referring to the non-isolated version? I purchased the isolated version. I haven't got to the wiring of them yet, although off the top of my head I think I will wire them independently of each other (perhaps with another busbar at the battery so the terminals are clean & I can add a fuse). From memory, those units called for 6 AWG.
