    Actually, captholli in his post #15, used the LIPB acronym for Lithium Iron Phosphate Batteries.
    And his post #17 suggested that LifePO4 was also a brand.
    Anyway, semantic aside, I think I'm beginning to learn what we are talking about!

    Do you possibly remember which brand of these batteries (however named! :)) you've got in your AB?
    I'd be surprised if they were Dakota, because around here they are unheard of.
    Which doesn't mean they aren't good, of course!

    LifePO4 is a brand manufactured in China by a mega battery plant that produces lithium batteries for all segments of industries. Probably should have this thread placed under a different heading / thread. The original topic was the San Lorenzo and "why"? for lithium aboard. Installations like the S.L are custom built battery systems with very sophisticated power management systems to control / shave to the main A.C. buss and I sat on the side lines whilst the battery powered catamaran thread was going strong here for pro's and con's but I can state that there are several vessels 150 ft + that have 1 mega watt + or over 1 million watts or more of stored battery power that can carry the entire vessels house load for 48-72 hours without any internal combustion engines running. Battery technology is catching up but vessels 150 ft and up that have them are designed around " Battery rooms"

    Actually while a manufacturer may have jumped on the name, LifePO4 is a generic term used by all brands of such batteries.

    In answer to Mapism's question of what brand we have, we have Renogy.

    I had no idea that LifePO4 was the acronym for Lithium Iron Phosphate, I learn something new every day. Now that I Googled different batteries, I see several battery manufactures marketing under LifePO4 . The jist of this thread with San Lorenzo Lithium or for that matter , Benetti, Feadship , Oceanco etc the batteries are all custom built cell stacks in proprietary enclosures and really don't resemble anything on the retail market as electrical automation companies are manufacturing battery systems for specific needs and applications.

    Specifically for Lithium (Li) Iron (Fe) Phosphate (PO4). So actually the chemical symbols. However, variations on this being developed constantly. You are correct that most LifePO4 in larger boats are custom built cell stacks. Actually a few cell stacks shown on the retail market. However, while standard LifePO4 batteries might be installed in runabouts or center consoles, those groups or stacks in larger boats are designed for that boat. The battery company and the builder communicate throughout the build.

    Now, back to the fire in question, I put no credibility to the statement that the cause was a "battery failure." Perhaps a do it yourself regular lithium installation but then that doesn't describe the current state of the art at all. More likely an installation or charging issue if battery related at all. Sort of a throw away line when likely the most known at the time was an electrical fire was suspected. I can't imagine Sanlorenzo installing regular Lithium batteries. AB/Fipa/Next and Sanlorenzo are accessing the same information and technology.

    The small sailboat cruising community has pretty much been on this conversion to LifePO4 for at least two years now.
    One of the popular YouTube channels featuring TransAt sailors Ryan and Sophie have been on the leading edge. I believe that Ryan is a principal or somehow related to Dakota LifePO4 batteries made in the US.
    Many others are using a product our of EU called SuperB. @mapism you should find information on SuperB I am sure of it.

    While I am being convinced that LifePO4 is indeed safe thanks to advancing BMS, I am still not sure it is fool proof as there are so many electronics that are involved in managing these beasts, what if electrical short or poor installation or vibration will cause the BMS to fault?

    As @Pascal stated earlier, this is now a very viable energy management, off the grid, whateveryouwanttocallit option for boats in the smaller range, think 40-45 foot sweet spot for sure.

    Probably because of so many bad ''Injectors''.......
