Hey, So I've read tons of postings and build threads and I think I've got it straight, but I want to confirm with those that have already done this. Here is the set up that I will install. Please let me know if you think Ive gone off the rails anywhere.

Isolation circuit:

Starter battery pos--> Blue Sea (BS) ANL fuse block with 300A Mega/AMG fuse --> BS ML-ACR Auto charge relay with manual control --->do I need another fuse block here?? --> positive terminal of house battery.

Starter battery negative ----> ground and to house battery negative

BS ML-ACR will also have contra switch and LED indicators wired to cabin

Need advice on wiring dual voltage indicator to cabin. Separate wiring direct from batteries?

Fuse box:

House battery positive --> BS ANL fuse block with 125A Mega/AMG fuse ---> BS 100A circuit breaker -->Do I need a low voltage disconnect here?? BS 12 circuit panel with neg bus --->relays --> accessories.

Does this look right?

Thanks,

Porrick

This is what I use -->DUAL BATTERY VOLT METER FOR TOYOTA PRADO 150, LANDCRUISER 200, 2016 HILUX

And yes, separate wire directly to each battery.

Thanks for the help!

Okay, maybe my questions were too general. Let's try this:

Does anyone here use a low voltage cutoff on their house battery? If I run an ARB or similar fridge, there will be a min voltage cutoff built into the appliance, right? So what is the advantage of an LVC -- am I going to ruin my deep cycle battery if I fully discharge it by mistake?

Thanks.

IMO it's not worth the cost to add a low voltage shutoff that can handle 100A. If you have individual items on the circuit you worry about forgetting I would add smaller low voltage shutoffs to those circuits. (Your fridge will have one built-in)
