I did same to mine last year - same as indicated above. Best thing I ever did, particularly for piece of mind when the stereo is on all day at a raft up. I moved everything from breaker panel to this house battery - I can run the fridge all weekend, as well as the stereo.
Either way thanks for the reply!

I don't think you want to install an ACR with what you are wanting to do. You are just adding a 2nd battery to your port battery/motor for a 2 battery house bank/start, (think of it as now 1 big battery) while keeping your SB battery/motor separate. An ACR is for 2 separate batteries (not paralleled) with 1 single charging source, for example; 1 motor and 2 batteries, (1 battery is house, 1 is start)
Just keep your battery switches set to that each motor and it's battery are separate from the other.

Personnaly, I'm not a believer of switching battery switches all the time, or running in the ALL position. My preference is to always have them set so 1 motor starts from and charges 1 battery, and the same for the other. That way you'll never end up stranded because you forgot to switch the switch once you reached your destination and ran them all down. The switches are for use for a dead battery start, always 1 good battery. IMO. But you ain't the only to run as you do and I'm sure you are aware of the possible result,
Deep cycles require a lot longer time to recharge. Not something short motor run time will achieve, at least for long term charging. If you are determined to charge by alt, have you considered upgrading to a high output alt? Need to change the alt wire too. Or if possible on board charger and plug it in in the evening. Best option if possible.
Disclaimer, I don't know how well 2 alts work together to charge 1 bank when the other is low when all are tied together. Just not my method, thus no experience. I guess it sounds good in theory
Ideally, you would send charging from both alts to the house bank, and then use an Echo Charge or an ACR to keep the isolated start battery topped off.
But then what you propose to try, it' simple, easy and requires no added accessories, just memory. see if it works for ya and tweak if need be.
Thanks

I have an ACR on my house battery also. Works great without fear of killing my port starting battery when voltage drops.
The "house" pulls against both batteries until voltage drops to 12.75 then disconnects the starting battery. It reconnects when starting is at 13volts hence a charge is present.
Sounds like your wanting to let your stereo kill both batteries and rely on your S battery to crank both engines. I wouldnt want to do that do to our type of boating long distances from shore. But, it depends on your level of saftey.
If it were me, I would install 2 house batteries with both house batteries set up with ACR on both engines to allow charging. Best of both worlds with piece of mind for both motors. I have been out there when an starting battery died and had to use other battery to start engine. If you killed the other with stereo, well, hope you have plenty of beer for the tow home :-)
Take care!

So 4 batteries. 2 start and 2 as house totally isolated from start except for the 2 ACRs between each side and possibly a battery switch for that super rare condition?
Is there any conflict of 2 ACRs working together?

Hey nailit! I hear ya, and that was my original thinking when I was reading about the ACR's. But I just couldn't figure how to accomplish the actual wiring. I hate being such a "diagram guy" but sometimes I just need to see it to get it. Do you know of any diagram of what you are describing. I'm interested in this thought!
Thanks!
Thanks!
