LiFePO4 Batteries: Discussion Thread for Those Using Them as House Banks

Yes it does help and reads real close to the fla battery basic report and most of it applies to all battery chemistries.

It’s very aspirational , other then a requirement for alerts from the bms , largely says very little other then making no allowance for LFP technology

Really ABYC should have supported LFP only chemistry for boats.

It disappoints even me and really, my expectations were low

Written as a political compromise among their industry’s masters

You know better then to make this demeaning comment because I have explained the process to you in laborious detail. TE-13 will be issued as E-13 later this month. All of the "shoulds" become "shalls".

As I told you very professionally and respectfully some time ago, the Standards are created by volunteers from all areas of the recreational marine industry including: the USCG, UL, boatbuilders, classification societies, equipment manufacturers, technicians, etc. The ABYC works hard to ensure that there is a good mix of each of the market segments so no one segment can dominate.

Further any interested party is invited to join in the process and submit comments during the review of the Standard. These comments carry just as much weight as comments submitted by committee members and each comment is reviewed and adjudicated.

I explained all this to you several months ago and invited you to join in with your considerable professional expertise. Your response was along the line of "I don't give my advice away for free so somebody else can make money off it..." which I found odd based on your 13k posts on this very forum. I tried once more to explain that the ABYC is a non-profit organization and any money made is plowed right back into its work. At that point I realized that you would not be swayed and I shut up.

That all said; you have no idea how difficult it was to generate TE-13 and try and keep it balanced so that this technology can continue to develop.

It’s pretty clear they haven’t really differentiated between the different Lithium chemistries. What advice is given is pretty common sense. The only thing that I’m not really doing is the advance notice of disconnect. But then, nothing on my Lithium house bank is safety critical. Engine runs off the lead acid starting battery

I couldn't agree more. <ranting deleted>

In case your BMS does not have the advance disconnect warning: you can connect another cell monitor, I’m not sure which ones allow to set alarms but bet some do.

This all will only work when you have access to individual cell terminals.

About that ABYC draft document being implemented: They are messed up in their heads. “Should” does not become “shall”, it must become “recommend” and really, at this level they should be ashamed of that document taking that long and at high school level at best, even though it’s just a recommendation.

I agree , the stuff about thermal runaway is Li generic , the recommendations are few and far between and the vast majority is aspirational. Sadly the ISO spec looks like it got written by the same author

No you have not. You have given your opinion again and again. And I fully disagree with it.

So list the industry entities that find their products are disqualified by TE-13. How many of them contributed to this? And how many of their competitors?

The average reader of LiFePO4 threads on CruisersForum knows more about it than what these industry experts write in this document. It’s ridiculous.

On retrospect most of what is listed looks like cut and paste from several manufacturers and mostly several of the LIPO Rv life forums . On here we all ( I hope ) agree the only chemistry we should use is LiFePo4. Which would make almost half of that document useless .

[newhaul]

About the only thing it did say specificly is that the bank needs a BMS. We all know that already .
Don't a fraternal group of entitled useful idiots to tell us what we already know

[CharlieJ]

Curse the darkness. Light a candle. It is up to you.

For me trying to explain in a courteous, professional manner and receive insulting comments in return, not worth the fight. I yield to your technical superiority and arrogance.

Hi Charlie,

I personalty found this publication very helpful, so I agree with you. I just finished a project with a local very talented engineer who introduced me to the world of LFP I largely misunderstood prior to meeting him. He have had a few similar but simpler projects completed before me and was very professional following due diligence making sure I understand what I get into. As one of the steps I sent this publication to him asking to review and comply (mainly for insurance purposes) and he got back to me with a feedback that this was helpful and some of the points were not covered by the design, so he has corrected it.

Now, I am going to read all the posts in this forum discussion to catch up with the community...

Bottom line, for users who are not super technical (like me) it worth using this publication and this webpage https://marinehowto.com/lifepo4-batteries-on-boats/ and go line by line with the designer/installer to make sure everything has been addressed. Fun never stops!

At same time, Rod of MarineHowTo - thank you very much for all the articles and knowledge sharing, glad to see your picture recovering! Best wishes!

I invite readers of this post to join me on this here: https://marinehowto.com/
