    If this was a battery related mishap and those batteries where Lithium I am getting more concerned for every boater who seems to be slapping lithium and solar and large alternators in their boats. Sure, Lithium battery in and of itself may be safer than years past but they still require sophisticated electronics to manage so much, I suspect these electronics can be mal-installed or stop working properly...?

    What I don’t get is why would you want lithium batteries on a 90 footer. It s not like you gojng to run the boat on batteries alone so what’s the point? Traditional batteries work and won’t set the boat on fire

    i can understand the appeal on smaller boats but not on a 90 MY.

    does anyone know for a fact that San Lorenzo buses lithium batteries ?

    Yes. The company that supplied the lithium batteries and technology for the San Lorenzo SX88 features this very boat on its website.

    Well, I don’t think “Pay More - Get Less” green energy test marketing was a success. So they’re stuck with having to make stuff up.

    RER, I can only see a reference to the model on MG website, not to this particular boat.
    Do you have reasons to think that the one burnt in Valencia was equipped with lithium batteries?
    I mean, at Sanlorenzo they would fit anything the buyer wants, and while in their range the whole SX line is the less targeted at experienced boaters (being the only one IPS powered, to start with), I doubt that all the (many!) buyers were silly enough to pay extra for lithium batteries, just to pretend to be "green", whatever that means...

    'fiuaskme, I don't get why would you want lithium batteries on any boat, period.

    I don’t know what to tell you. I don’t know what you’re looking at. Pascal included the link in his post above. There’s a photo of the boat at the top and the rest of the details are there big as life.

    When I referred to “this very boat” I was referring to this very boat model in answer Pascal’s question if San Lorenzo used lithium batteries.

    I'm looking at the same website as Pascal and yourself.
    Which does show an SX88, but with no evidence that it's the particular one which is being discussed.
    They built dozens of them.

    I answered you above. Did you read my reply? I’m not going to argue which shade of blue the sky is.

    It seems to me that you didn't read my question.
    WHAT makes you think that the boat on MG website is not only the same model, but exactly this "Pesa" thing?

    …lol, you figure it out. I’m not going down your rabbit hole.

    Rabbit hole?
    Pascal asked if SL uses lithium batteries, and on top of answering yes (which would have ben correct in general), you specified also on this very boat (which as we all understood by now, is something you have no clue about).
    This is what triggered my question, not the desire to drag anyone down a rabbit hole.
    Why so many people think that answering "I don't know" to a question is a sort of disgrace, I wonder?

    Lithium Ion batteries are inherently dangerous and will combust if overcharged, damaged by puncture, crushed or exposed to extremely high temperatures above 180 degrees. Lithium Ion performance degrades drastically under 32 degrees f and over 130 degrees f. and cannot be charged after reaching those temp points.
    The new Lithium Iron Phosphate batteries will not combust by any of the above means and are 100% safer and have been in the marine marketplace for about 1 year now & the advantage for any lithium battery will be 50 % weight reduction over AGM. Lithium has a 80-90 % charge rate vs 50-60 % charge rate with AGM and the biggie here is charge cycles and warranties. Lithium Iron Phosphate batteries will give a charge cycle of 8,000 vs 700 - 1,000 cycles for AGM. LIPB warranties are 12 - 15 years whereas AGM are 2 years. LIPB's also have a much higher charging density so they don't discharge as quickly as AGM. BUT the cost factor for LIPB is three times that of an AGM but the LIPS will out last the AGM by 8-10 yrs. before replacement is needed. I would take Lithium Iron Phosphate batteries for less weight, Higher charge density , 8,000 charge cycles and 15 year warranty over an AGM system.

    Thanks for the highlight.
    I wasn't yet aware of these LIPBs, but they sound like worth looking into.
    Which brands would you suggest to consider?

    State side Dakota and LifePO4 are two of the players. Its kind of the wild west manufacturer wise between applications of auto, commercial land movers and marine with many different companies manufacturing. One other great aspect of LIPB is the number of cells fit into one size casings . You can have either 12v, 24v, 32v, 48 volt cells in one case @ different AH so that's a big advantage over series and parallel wiring on most banks.

    We have LifePO4 on our AB. As Captholli says Lithium Ion have serious safety concerns but LIFB has moved well beyond those. Dakota and LifePO4 have been doing this for a while.

    Lithium battery technology is rapidly moving forward and many proven technologies and companies.

    @captholli: great, thanks again.
    @olderboater: interesting to hear of AB, but by "LifePO4" do you mean the type, or the specific brand as mentioned by captholli?
    I'm asking because I just checked the distributors I'm familiar with, and found neither that, nor Dakota.
    On the other hand, I noticed that Victron (widely used on this side of the Pond for both batteries and electronics, but so far I've only seen their AGM and GEL stuff) now include also LIPB in their website.

    LifePO4 is a type, Lithium (Li) Iron (Fe) Phosphate (PO4). Dakota is a brand. LIPB is Lithium Ion Polymer Battery.
