Dual Battery Setups! Let's see them! Multiple Batteries Thread!

I ended up putting the switch next to the switch blanks on the driver side (added another one there too). When you have too many switches, you gotta get creative lol


As for the lights on the switch, both go on when both batteries are being charged. This usually happens automatically a couple of minutes after you start the engine, or if you manually connect the batteries (by the rocker switch or the actual unit using the yellow lever/button). The lights on the switch turn off when the batteries are isolated (car off or manually disconnecting). Hope that answers your question

 

Thank you sir.

 

One more question when both batteries are engaged the yellow button pushed down correct??

 

yes

 

Isn't the yellow pushed down manual override?

 

Do you think acr switch button to a fuse block which is connected to the house battery instead of directly to the battery would make a difference? Is that where acr sense voltage?

 

When you push it, that's your manual override, bc you're manually pushing it down lol

When you let it turn on by itself (or with the rocker switch), it gets pushed down automatically.

Every time it is pressed down or depressed (either automatically or manually) you can hear the click of that button in your engine bay. I can hear it from inside cab. And when I turn off the truck, I can hear it depress as I walk away.

 

Doesn't matter

 

There is one thing that's annoying about the Blue Sea unit.

After a long few days of camping and not driving, my fridge, lights, and other accessories (all hooked up to my aux battery) will drain the battery down to like 8-9 volts. But the thing is, the ACR unit will not auto connect if it senses that one of the batteries is super low on voltage. So what I've done to remedy this is I manually press the rocker switch to connect it, then finally after a long time of driving and the alternator finally charges it back to something decent, the ACR unit will finally connect automatically.

Also, one time when this car cut me off (so bad that I had to break or else he would hit), I tried speeding up to catch him. So much that my RPMs were super high and my alternator (high output 250a) I guess was charging so much that the ACR unit disconnected the batteries - I guess for safety.

 

Sounds like you didn't relocate the voltage sensing wire. I plan on relocating mine all the way back to tap into my rear 12 v plug in the bed as far down the line of connections as I can get it. That should keep your voltage output perfect at all rpm ranges. Otherwise it's sensing and adjusting at the stock fuse block and could be putting out way too much or too little into your aux terminals

 

Anymore info on this? Thx

 

In regards to the batteries not connecting when the house is low, is designed to do that. Or at least until the starter is fully charged.

 

My switch has apparently decided to stop working, and I've been lagging on contacting bluesea.

 

This happens when the aux battery is low. My house batt is never low bc all my electronics (except winch) is hooked up to the aux batt

 

Yeah I went back and re read your post, that's weird.

 

my house battery is perfectly fine and the blue sea will not turn on automatically . But if i throw on the manual enable everything works fine Not sure what to do :/

 

How long have you waited? It takes like 5 min after the engine has started.

 

On Monday i drove it 30 minutes and it still did not click on. I was on the freeway.

 

Anyone use a charger to keep your batteries topped off? I've got a super short commute, about 5min and it really isn't enough to charge my starter let alone the house.

 

i use a oriellys 3 amp trckle charger.
