Before you do parallel strings take a look at this: https://www.orionbms.com/manuals/pdf/parallel_strings.pdf

Have you checked out this page? It looks like Victron supplies an app which includes a cable gauge calculator. I haven’t used it but it might be what you are after… https://www.victronenergy.com/blog/2014/10/02/victron-toolkit-a-new-app-for-android-and-iphone-users/

Hi! I am doing a complete repower of a 1953 wood boat with Electric Yacht motors as well! More info here: ‘Advice Building an electric boat' https://diysolarforum.com/threads/advice-building-an-electric-boat.38409/ It looks like maybe you are working with PYS in BC? If not you might want to...

Thanks! I can post pics if everyone wants

Wow great point I didn't even think about the temp vs flames distinction. @David Collins Elide seems to activate after 3-5 seconds of flames. Any thoughts on this? Thanks!

Also I think @Will Prowse pointed out in this thread that maybe other chemistries reignite but LFP would not: https://diysolarforum.com/threads/can-lifepo4-batteries-combust-in-thermal-runaway-event.999/post-599432

Thanks for your insight! Thats Elide vs. ALO effectiveness distinction is news to me. Could you share the source?

Just an update. I switched to 48V motors, Victron Inverters, and am using Orion 2 BMS which "talks to" the Victron.

I 100% agree with you. I was very surprised that a BATTERY MAKER would use the term so loosely when it really means something different!

@Will Prowse Thanks for everything you do! You are an amazing resource to me! What do you make of this statement from Relion: "In extremely rare critical failure scenarios (i.e. severe physical damage from a crash or abuse of the battery in extreme applications for which it was not intended)...

Hi everyone. Just want to throw out an idea and see if it helps. I am building an electric boat with 4 sets of LFP batteries (150kW). My understanding is that the LFPs don’t suffer thermal runaway ON THEIR OWN but in a mobile application like mine I worry about scenarios where the batteries...

@Will Prowse Could you clarify why the battery behavior in the “spearing” video isn’t an exothermic reaction resulting in combustion? It doesn’t seem like the spear provided a spark. It looks like a second major puncture resulted in a fire, no?

Thanks very much. The Nordkyn website articles are indeed excellent! And I reached out to custom marine! Thanks again!

That is super helpful thanks. Would an installer know this or is there a vendor who could put that system together on paper for me? Do you suggest just building my own batteries from cells or is there a good battery brand which works with these BMSs but doesn’t have a massive premium? Thanks!

Thank you for taking the time to respond.

Hi all! Newbie here so forgive me for my inevitable mistakes. I have searched the forum for similar threads but might have missed them so I am taking the plunge and posting my own question. I am converting a 1953 wood boat (42' long, 25,000lbs) into an all electric boat. Don't ask me why...

As a commenter recently said in a great YT video on this subject, ambient heat has a large impact on cycle life so there is an ROI in keeping the pack cool. I am in the process of building a large pack for my all electric boat (1200Ah @ 108v using 144 EVE 302s). I have successfully used a...
