Anybody know if its safe to use an ACR inbetween two banks on an onboard charger? I don't wanna mess my ACR or battery.

The ACR is only connecting the batteries together when charge voltage is present and separating them when a draw is occurring. It cannot differentiate between your alternator and a converter.
So, go ahead, it's OK.

I use a single bank with my acr to charge both batteries.

I ended up using a dual bank with my ACR. I found that if I had the charger only hooked up to the starter battery, in the "maintenance mode" the house batteries were never combined thus not maintaining them. So now when it charges it combines them both, house and starting, and maintains all the batteries.

It depends on the maintenance voltage of the charger and the minimum voltage the ACR combines. Mine stays combined even in maintenance mode.

To clarify, if using a single bank charger with an acr/switch (ala blue sea add-a-battery), you'd hook the positive end of the charger to the same post on the battery combiner switch that you have your positive from the alternator hooked to, and NOT hooked directly to one or the other battery, right?

Just hook it to one of the batteries. After several hours check to see that the light is still on, on the ACR. If the light is still on then they are staying combined during the maintenance cycle. You are then good to go.

I guess that makes sense. You'd want to put the charger on your "deader" battery, then, right? I know some acrs (again blue seas in particular) won't recombine if the voltage of one of the batteries drops below a certain threshold (11.7v IIRC).

I would wire it to the house battery.

i have a two bank charger so if i "straddled" the ACR I should have no problems.... I am correct in understanding what has been said?

Just use one bank of it. If one battery gets too low for them to combine, you can manually combine them with a switch.

well without me installing a switch I think I will use both banks and then when I charge I will disconnect the ground on the ACR. This should keep it for combining the two banks and I won't have to worry about anything since the ACR won't be on...
