X2 battery Relocation

I have a 2007 X-2 and decided that I did not like the battery setup. Apparently in 2008 or 2009 dual batteries became standard and was done in a neat, trick way. I took it one step further and moved both batteries to behind the rear panels where the ballasy pumps are. They fit, but the panel it at a slight angle as opposed to being perfectly perpendicular. Whatever I use those rear compartments for ballasy anyway. My boat only had a single battey and then 4 wires to each post, dumb, dumb, dumb. 1 wire to front harness, 1 wire to amps, 1 wire to ballast and one wire to engine. Here's a list of what is needed, makes you kinda understand why msrp goes up every year on our boats.

60 ft 0 awg copper wire to feed batteries
100 ft 4 awg copper wire for amps, jumpers and acr(automatic charging relay) connections
10 0 awg lugs
20 4 awg lugs
6 2 awg lugs
1 hydraulic crimper 00-10 gauge
1 blue sea 7610 ACR
1 blue sea 8686 battery switch panel with 24 hour circuits
5 80 amp car stereo fuse holders and fuses
2 blue sea marine terminal blocks with covers
100 ft 1/2 inch wire loom
50 ft 1.25 inch wire loom
1 24 series battery box
Stainless Steel screws
cable ties with screw hole
heat srink tubing 1/2 inch and 3/4 inch
noalox gel for connections,available at home depot, prevents corrosion
20 ft of 12 gauge wire for bilge pumps and starting isolation circuits
10 12 awg lugs
1 15 amp waterproof fuse holder, for acr
1 20 amp onboard charger, optional
1 red 5/16 terminal lug
1 black 5/16 terminal lug
1 package of battery terminal covers, rubber

As you can see, alot of material is needed. I am not quite finished. I am going to take some photos of what this looks like this weekend. But I wanted to start the writeup.
I wanted to move the batteries to the back so I can use that storage under the seats where the stock batteries are for waterskiis, etc.
I had to rotozip the hdpe on the left rear panel and move the ballast timers to the rear hatch compartment, my switch is under the seat. Stock location on 08-newer boats.
Before I continue, does anyone care about doing this?? This is going to be alot of typing and photos......

I am thinking about doing something very similar w/ my '06 X10, very interested in seeing your pics/write up. Who knows, it may even inspire a few others to do the same.

Thanks in advance!

Wiring diagram

This is pretty much how I wired it, from blue seas site, I cannot take the crdit for this diagram, but it gives you an idea. A few differences, Both of my negatives from the batteries go to a negative distribution bus. Also the alternator is tied into the starting wire of the battey switch. More photos to come once I get down to the boat.

That diagram show an alternator wire going to the battery, do you have that?

My 02 XSTAR only has 1 pos. wire, and the ground coming from the engine, and I believe the alternator is connected through the starter. Just wondering, because Im in the middle of buying all the components for a Dual battery system, using a perko switch.

I'd love to see some pictures of this. I'm adding an on-board charger to my dual battery setup, but nowhere near your project. Does the factory put the dual batteries under the observer's seat in the '08-'09 boats?

I was going to go with the blueseas switch as well, but switch out the 24 hour thermal circuit breakers with 15A switch breakers (like the main DC house voltage). That way I can flip them and not worry about the bilge or radio draining the batteries when the boat is in storage. I've seen a few posts where the switch is off and the batteries are still drained, like the post Turbosdad put up few weeks back.

Ron, do I have to come by tomorrow with my digital camera?

The factory puts the dual batts haphazardly under the observer seating in the 08/09 boats, to answer someone's questions. I say haphazardly just because to me - they seem like they are just sitting in random spots on the floor, with covers that don't exactly fit. In an odd place - it does cut off the 'flow' between the cooler bench compartment and observer seat compartment. Just not very tidy, or well thought out, imho.

Definitely worth posting the photos and details of this project.
