Blue Sea Add A Battery Install

[cab13367]

Great pics of your upgrade. I am new to the boards. I have 2000 Outback LS and adding a battery and looking to redo the whole battery setup. Can you help me with why the thermal circuit breakers are the way to go?

Two reasons: (1) If they trip, I can just flip the lever to reset. Don't have to worry about carrying extra fuses. (2) I have an onboard smart charger (ProMariner ProSport 20) that can direct more current to the battery that needs it (usually the stereo battery) but I also have an Automatic Charging Relay that will combine the batteries once it senses the charge, thus defeating the benefits of the smart charger. So when I plug in my smart charger, I open both the thermal breakers which isolates the ACR, which means it can't combine the two batteries when the smart charger is plugged in. Make sense?

Al, what is the black item right under the battery switch?, then what is the next item down?
Thanks

That's the Blue Sea Automatic Charging Relay (ACR). When the boat is running, it automatically combines both batteries so that both are getting charged by the alternator. When adrift or anchored, it automatically isolates the batteries so I don't accidentally run the starter battery down. I set the battery switch to ON and forget it.

What kind of Thermal Curcuit breakers in these pics? Trying to find them online for my system...

Thanks

They are made by absolute. I got them here, except the new ones have a built in digital amp gauge.

Sorry, the correct term is not welding calbles but "welding leads". Just had to get my 2 cents in....

Right! Leads is the right term, not cables. Thanks for setting me straight.

Dumb question here; does the house battery side just power the amps or does it do some of the other aux items like heater, blower, lights etc?

I have the helm bus (which feeds the heater, blower, lights, etc.) and starter connected to the house battery and the head unit and amps connected to the stereo battery.

with all my new exile equipment i am debating adding another battery. i have the stock 2 battery set up but i may add a 3rd, 2 batteries for accessories and 1 for cranking

Since I added a third amp this winter, I am going to be adding a second stereo battery this spring just to make sure I don't run out of juice on those 3 and 4 day weekends with no access to 120V power in between days on the water.
