Default Battery Question

I have a couple of questions regarding batteries - hope to get some help.
I have three battery banks - see included photo.
The Port engine and Generator Batteries has a starting battery and a deep cycle battery.
The forward battery bank (one center right) has a starting battery and a deep cycle battery.
The center left has two deep cycle batteries.
I do not have the Inverter battery option.

It doesn't make sense to me to have a deep cycle and starter battery connected together. That battery should simply be the starter battery for teh starboard engine and the other set the starter for port engine and generator.

The third set of batteries would be the house batteries (should be all deep cycle). Did whoever I bought this boat from not know what the heck they were doing or am I off base here?

Thanks in advance!
Scott

Scott,

4100 SCA also. Like you no inverter battery (but will probably add one in the future).

In each of the battery locations on your image (I'm looking at the same thing in a 2000 4100 SCA owners manual) I have a single 12V 8A8D w/1450 CCA, not two like you do.

Scott you did not say what boat model or year you have but I assumed it’s a bigger boat like Paul’s. I agree a bank should not be made up with starting and deep cycle batteries. The set up Paul has is a good way to go IMO.

Default Thanks!

Paul,
That helps knowing what you have since we have the same boat. Do you have the two boxes in the center? I have a total of 4 batteries in those two boxes. One box I am thinking should just be the starting battery and the other would be the house batteries. Then the box for the port engine and generator should just have the one starting battery.

I would like to get the inverter batteries as well!

Scott

Yes, 1999 4100 SCA. I will be spending some money on batteries this spring.

Yes, two nice battery boxes centerline and one between the stbd engine and the seacock for the AC raw water pump.

I have a 95 2700 with one cranking and two house batteries and this is what I use for the charger. Each battery is charged, maintained, and monitored separately. Works perfectly!

Hard to get a better performing product than ProMariner IMHO!
