Why did you buy golf cart batteries when they were so inferior.

That said, I'm all in on adopting new tech that makes sense. Progress is real, which is why I love my new(er) anchor, my composting head, and probably a bunch of other stuff we have.

I know "drop in" is not as simple as that. There are other changes that need to happen on my boat, so I'm here to learn, so I can make an informed decision about how to best make the switch.

Loving the real-world experience and info. Can do without the condescending preaching.

IMO if you can get 9 years out of your lead acid, then the only benefits of LFP is lower weight. Other things like faster charge acceptance, lower discharge floor, no worry about partial state of charge really doesn't matter. The only other thing would be if you had some electrical item that liked higher voltage (like a Spectra watermaker) or did a lot on night passages on autopilot.

Whether LFP drop-ins are "drop-in" depends on your electrical system now. I got 4 $300 drop-ins and only charged setpoints on boat with nothing that had a "lithium" setting. Took off 4 days later to Bahamas for 4 months never on shorepower.

Little did I know that buying Lithium at multiples of the cost which will burn your boat to the waterline at sea was better!

Multiple times the cost? No, pretty much comparable or less than LA if starting from scratch.
Catch fire? No, this article written by the president of ABYC

You might want to educate yourself before posting. LiFePo4 are not subject to thermal runaway in a manner other lithium chemistries are. They are widely considered to be safer than lead and AGM batteries.

Hey, you completely thread drifted my thread and completely changed the subject to lithium. The thread was about fork truck batteries being superior to golf carts.

Oh, I get it Boatpoker and Mike OReilly , it’s not ok to be condescending but it’s completely ok to thread drift and completely change the subject of people’s posts.!!

Mvweebles, what do you think of that, sounds very very impolite to me. Much worse than condescending!!

If you read your initial post you will realize your the one that made this thread about lithium

I think my Original Post „shows“ why they were superior. But it’s sort of a thread based on the past, it’s not really to represent current lithium thinking..

What does this mean then…

I think you are a 'right-fighter.' Someone who has to be right even in the face of total defeat. The smartest-guy-in-the-room.

You can control how your message is delivered but not how it is received. You're pissed that you cannot control the conversation about forklift batteries when that was a red herring to begin with - you have an ax to grind to support lithium. Not enough for you that people are quickly adopting the technology opoortunistically - you want them to tear-out FLA/AGM systems that meet their needs perfectly and go Lithium NOW.

As far as Mike O'Reilly and Boatpoker, you happened to pick two people who's posts I respect and look forward to reading. Mike is an exceptional writer and takes very thoughtful positions that are well described and supported. He's a very respectful poster. Boatpoker is a surveyor with vast knowledge that he freely shares and rarely gets into pissing contests. Somehow, you managed to cross paths with two of CF's best contributors. Go figure.

Yeah, I know Lithium Batteries work very well.

We have been using them for years as BIOS Batteries in all our computers.

They last so long sometime folks/techs forget about them when a computer doesn't boot-up properly.

Thankyou Mvweebles for your input.
Do any of you know how hard it is to install and test a technical solution and then create a thread on this.
It is extremely difficult from the testing perspective and then we have to put up with the negative comments on here.
I know…I have had a few run ins with Jedi who also starts technical threads. I don’t always agree with him, but at least we create an environment of moving forward. Jedi knows a lot and I have a lot of respect for him…

This is how I see it as well SB. I really haven’t found a compelling reason to make the switch yet. I think it’s a better technology, but making the switch comes at a cost, not just of the new batteries, but in redesigning parts of my charging system. I’m learning there are relatively simple ways around these issues though, which is what I’m appreciating about the discussion.

See… this is great to hear. Thanks.

This site is loaded with tech nerds, and you named one of those that is totally obsessed with his techy projects.

I have a few at work just like that who can bore the hell out of you with long troubleshooting stories.

I'm like just tell me what fixed it so I can note it on our monthly report which details all repairs, Cyber Security Scans, and usage on all our systems. (simulators)

I know how to troubleshoot and don't need all the details.

I guess the obsessed ones are lucky though and are in the right job whereas the rest of us can do the job pretty easily, but to us, it's work not fun.

I do enjoy messing around with the solar setup on my boat though and building chart plotters with old computers or RPi's using OpenCPN.

Okay… but Mvweebles, but this was not really the question…
It was the sentence you highlighted…. What’s your opinion on that

Here is the sentance that was highlighted: "Mvweebles, what do you think of that, sounds very very impolite to me. Much worse than condescending!!"

What do I think? I think Boatpoker and Mike O'Reilly were being polite under the circumstances. I think the rude, impolite, and condescending award goes to you. Seriously, do you really think you can kick-off a thread on the back of "Lead of Dead" and think it's a "technical discussion" on forklift batteries? If it makes a difference, a quick Google search shows a lot of LFP fork lift batteries so the old-school technology is apparently being displaced.

I think you may want to take a break from this thread. Rule #1 - stop digging.

Yep, I think I’m getting it Mvweebles, so you Mike and boatpoker think it’s completely ok to take over other people’s threads if you consider them to be Axxxxxxxs.
I guess you important guys are allowed to make your own rules.
Strange, I thought Mike OReilly was a squeaky clean polite guy.

Well, could be there's a consipiracy against you. Or it could be you're just outside the pale. Granted the constructive criticism is pretty heavy on the 'criticism' side, but I'd encourage you to consider your approach needs adjustment - there is no consipiracy against you. A bunch of strangers read your posts and arrived at a similar conclusion: You're a whackadoodle.

If it helps, as a trawler guy, I've often felt I don't get a seat at the 'adults table.' The Cool Kids on CF don't take well to powerboaters despite my having interesting creds (past full-time delivery skipper, current distance cruiser, full time liveaboard, etc). Aldus Huxley's boating-adapted version of Animal Farm: Sail = Good. Engine = Bad. It's a reason I don't participate here as much as TrawlerForum which is a much nicer forum.

If you have issues with Mike O'Reilly/Boatpoker, you might want to move on from CF (do not under any circumstances try SailingAnarchy where you would be crucified unmercifully). From my perspective as a shunned powerboater, they are reasonable - the cream of the crop.

I have to say, you made my day with the suggestion I might be one of the CF Cool Kids.
