Do you use your VSR??

[shawndoggy]

no

The concept is that people would want all the juice topping off a strater battery before any others.

Just FYI, they don't all work like that. The blue sea add a battery that a lot of people use is just a "dumb" combiner. When the voltage from the alternator passes a certain threshold, the combiner puts both batteries together so they can be charged. When the voltage drops below a certain threshold, the batteries are separated. So the loads from the two batteries aren't combined together, but there's no way to really ensure that one battery is "topped off" first.

I need to educate my dealer on that then. He told me that was the whole purpose, so that alternator amperage was not being drawn to recharge stereo batteries as a priority until charging was not necessarily full, but voltage was high enough, so, I think maybe same thing just expressed more accurately by you.

I believe that there are other, more expensive systems that work the way you describe. The blue sea add-a-battery seems to be the most common system, and it doesn't work that way.

Here's a bassboat example (no personal knowledge or experience with it... just posting to show what I'm referring to): http://www.stayncharge.com/proddetail.php?prod=SNC-AllCharge1224

this is what I use:

Thats what I have on the boat...and is not what is shown in the 2010 manual.

Is that not the VSR? ANd I have no Idea what VSR is/means?

Read my replay above I explained it. The bottom black module is an ACR, the red thing above is a battery switch.

Vsr = voltage sensing relay (the black box in the pic) = yes you have a vsr. Aka acr (automatic charging relay)
