I don't have ammeter, yet, on main lead from alternator so I can't say what max current I see. Mind you I doubt I'd ver see as much as 65 A. I don't let the aux battery become deeply discharged ( have solar panels).

And assuming the alternator can put out 90 A, when hot, pulling 65 thru to the aux leaves 25A for the rest of the van. It seems very much like an outlier situation.

The one thing about the blue seas acr which does give me pause is the max current allowed during forced combine. As in the starting battery is dead and you want to use aux to start van. I haven't had to try it but I wouldn't want to crank more than a few seconds.

Never found the current rating a limit.
