Ttmott I like the sound of this set up I’m following also.
I just don’t think we’ll keep this boat long enough to invest in another project like this.
 
Lithium battery life is dependent upon their temperature environment. Charging and discharging need to be within 18 Deg F and 140 Deg F with optimum charge and discharge rates in a narrower range. Locating them in the saloon area makes best use of their capability due to the tighter temperature control. Also, for the most part this is unused space in the boat and as the batteries will never require service for a life cycle of at least 15 years it's perfect and also opens up quite a bit of useable space in the lazaratte.
Thanks for the info. Very interesting stuff.

I won't keep the boat long enough to realize the payback either but it's such a cool project and simply steps the boat up to another level of comfort. Lithium technology is an area where sailboats, RV's, and alternative energy are really leading the pack; SR was heavy into looking at the supercapacitor start modules like the Maxwell units just before they terminated yacht production and I'm sure they were also looking at the LI technology as an evolution because it brings so much to the experience. The technology is mature and will replace lead acid; however to retrofit one of our boat's systems requires the entire electrical system to be changed which is where the real added cost is. If you really want to see some impressive LI systems look into the larger exploration yachts; I am lucky enough to know the owner of a large Nordhavn and the electrical systems including the lithium battery banks are impressive to say the least - whet my appetite...

My thoughts as well in regards to cost. I have to believe the cost actually exceeds simply replacing a generator after putting a ton of hours on it. Yes, there is the quiet factor but at night I barely hear it with the ac running and in the morning if you want piece and quiet, simply shut the genny down for a few hours. I think Joe's and Greg's set up is the cost effective option which I plan to do when life stops getting in the way. But I agree it seems like a cool project if you take the money aspect out of it.
So my guess is being you live in the space coast area of Florida, you work for NASA or one of their Contractor's? You definitely seem to know your stuff! Looking forward to following the progress. Thanks for sharing.
 
Definitely a cool project I agree with COD you know your stuff. A little over my electrical knowledge ( ok a lot) but I’m intrigued with gadgets and automation please keep us in the loop

Materials and components for this project are close to $16K. I enjoy doing this kind of stuff so I'll do most of the installation work which is a big offset; to hire it out would be a big nut to crack. I retired from Lockheed Martin now own an engineering and program management company so we have the resources to design and develop a system like this and a deeper capability to work with manufacturers and developers.

I completely understand your position on this. I just did a ton of upgrades on my boat, replaced MFDs and radar that was working fine at the timeouts to have the newest and best, replaced the shore power cord because it was a little marked up and I wanted to it longer to reach farther away pedastles, ETC. In the end they are boats so there really is no “good” investment we can make in them but they are all fun projects.
 
I just completed installation of all new Garmin gear, replacing all the Raymarine equipment the boat came with, plus some new stuff.

The new Garmin 8616s just barely fit, but they sure are nice! Technographics made the new panel, plus panels for the VHF speaker and keyboard. It was actually cheaper to put the Garmin keyboard in than to have the hole from the Ray keyboard filled in and gel coated.

Looks Great, I love the big Garmin screens. They fit perfectly on the dash.
 
They were a very tight fit, and required a lot of trimming behind the dash panel. But I agree they're really nice!
I had the same issue with the Axion XL 16s. It was a tight fit.

Is anyone else missing anode ports on thier QSMs? The QSM specific anode kit I bought from boat zincs has 3 large and 4 smaller anodes and diagram from SBMAR site shows 3 anodes on the stainless piping near the aftercoolers, I only have 2. I am missing a bung on the stainless
Pipe going over to the raw water pump. I also only have one port on the tranny cooler open for a anode because the other one has a line going to the shaft seals. I am assuming this is all factory but if I am the only one missing them then I will worry about it.

I have a zinc on the crossover pipe. Not sure why you do not. I can tell you that the zinc is never used up and i move it down to the bottom one as those get used up each season. I also only have the one zinc for the gear cooler.

I wonder is the water drains out of this pipe at rest and it was determined that the anode was not necessary because of that.

Mine is the same as Dstick's.

Mine is the same as yours. Seems I read somewhere the later engines did away with a couple of the zincs. I think the third time I change them I'll have a complete set on hand for the next change.....
