Battery Charger for Dummies? o_O

Here is what I has currently.

You have the same setup I did so you need to spend ~$85 on a DVSR. The one thing I wish I had done was move the batteries all the way forward in that compartment using longer cables and bus bars (http://www.amazon.com/Blue-Sea-Systems-Common-5-Gang/dp/B000OTJ89Q/ref=sr_1_13?s=boating-water-sports&ie=UTF8&qid=1395715675&sr=1-13&keywords=marine+battery+terminals).

If you have a switch and already have dual batteries Norboo, I am missing what you were wanting to do....I must have misunderstood, I would just go with what you have. No need to reinvent the wheel unless it won't get you to where your trying to go. Sounds like you only need a decent shore charger.

I am pretty handy and know my way around tools and audio, etc... but this is my first time working with a battery. I needed to understand what I have and what I needed to know what I want.
I need a on-board charger. The charge in the battery compartment is a shore charger.
I do need to move the batteries around but not sure how I wanted them arranged yet.

Marine Boat Battery Chargers : Which Type Do You Need?

That's my video... thanks!

If you have no AC power, have you looked into solar?

So does the Blue sea add a battery kit not charge the house battery while the engine is running ??

Yes, if you set the ACR on the battery side of the switch, then the ACR allows engine charge to go from the start battery side to the ACR, it senses an appropriate charge, and lets the current pass to the house battery. If however, you wire the ACR on the load side of the switch, it will not close and allow current to pass to the house side bank. Guys that have very different battery banks set theirs up this way. Guys that have similar battery banks will use the ACR on the battery side. You can wire the ACR directly between the batteries like the Blue Sea diagram, or you can hook it between the Battery side posts on the switch...it is the same in either place. I can add a few diagrams if you like...

Actually, either way it will take a charge from the engine and send to house battery, because the battery switch will be ON whenever the engine is running.

I think what @txav8r is talking about is when you use a single-bank charger on the start battery with the battery switch off.

So I think I did it right per your wright up. On the acr terminal A went to the start battery and terminal B went to the house battery. Am I correct? I have the switch wired just like the diagram

Did you connect the ACR terminals A and B go directly to the batteries, or did they go to the BlueSea master battery switch? It works both ways, but there is a difference.

 

[wakeformer]

They went to the batteries i added 4 new 4ga lines to the boat

House battery has one line going to acr on b side and 1 line going to B side on the switch
The start battery was done the same way but on the A side

 

[maboat]

In that case, your ACR will work with the engines charging and the battery switch ON.
It will also work with the engines off / battery switch OFF and an external charger connected to the start battery

Awesome thanks
