Hi John,
We do not at this time have a starting battery.
The setup is from the PO and is a four house battery bank, they are in the hanging locker in the master state room.
We have a 36’ sail boat. We plan on cruising.
We want to move the four six volt house batteries and add a starting battery. We are going to move the house batteries to under the satee and add two more for a total of six batteries.
The added two and the AGM conversion for the house batteries will be done at a later date, or when the 4-6voters die.
We plan to have all AGM batteries but do not want to throw out the 4 – 6volt batteries yet.
We plan on keeping the AGM starting battery separate using say a trickle charger to keep it up and the alternator to charge it when the engine is running of course.
We are currently installing a host of other equipment and want to keep using the boat.
One reason for the AGM for a starting battery is that the space for one is over the PSS shaft seal and they recommend no gas emitting batteries by their product as it wrecks the rubber. Plus like I said we plan on changing to all AGM in the future.

We have all the equipment except I have not yet purchased the cables.
I thought it best to actually move the batteries facially first then buy the Xantrex cables and windlass cables. Also using some existing cables until we can replace them. This current setup is about 20 or more years old. Original battery charger is 30 years old.
We have two anchor windlasses.
We have three battery selector switches.
We had four; I have remover one to the old bow windlass.

What we are in the process of doing.

Moving 4 – 6 volt batteries
Installing 300 amp fuse
Installing a shunt
Installing a 110 amp slow blow breaker
Installing the Xanterx 2000 charger inverter\ getting cable sizes and lengths
Installing the Link 2000 battery monitor
Installing the Blue Sky controller
Installing a 135 watt solar panel on top of the dodger
Re-routing all the cables from 3 battery isolator switches a two anchor windlasses’.
Removing old original battery charger and some cabling
Installing the anchor windless and battery cables to the new battery bank location about 30’ of a cable run.

Not necessarily in that order.
There is some wood working and other not so miner details but that is the gist of it.
