This CHARACTER has a Phd from Doofus Maximus University of Dorkville. seriously he's clueless !
Doesn't know that LFP IS LifePo4. Doesn't know what a LiPoly is or what is a 18650 MNC or NCA oivey.
It's just so funny because it's so sad. Maybe next time he can build a rocket to prove the earth is flat too.

Hey, I resemble that remark! ?
Joke all ya want, but many here have already had that rude awakening in their first few months of lithium ownership. The next five years here might be a crying fest when all the China batteries that were expected to last 20 years are dead in just a few...

I think he called out Will...anyone catch that? 4:40 mark

generally speaking, he is right, FLA is good in many ways , is cheap, an can last 10 years and more if properly used.
The only drawback is the huge weight and space needed that is not very compatible with mobile use.
Lithium has its strong points too.
And there is as much types of FLA technology than there is type of LFP ones.

I see what you did there.

I'm probably the biggest LA fan here, and I've been using them in banks for over 3 decades.
I'm probably also the biggest lithium fan here, and I've been building with them for over a decade now (longer than 99% of the fanboys here I'm sure).
When I defend LAs, it's not because I think they are better, or because I'm an old fuddy duddy stuck in his ways (I'm "only" 45, but that feels ancient with all the young Bernie Bros here). It's because I'm trying to keep people from making expensive mistakes. LAs from the local store are cheap, don't have crazy shipping charges, and they do what they are supposed to do, usually for at least as long as you expect them to. And if they don't, they have a warranty.
Lithiums are small and awesome. The quality cells are not cheap. They will not last forever as most fanboys believe. A high quality cell should last about twice as long, or a little more, than a quality deep cycle LA. A used BYD with only 60% capacity left will be dead in 1-5 years. A cheap blue china cell from XYZ looks great at first, but I bet most are almost dead within 5 years.
Why do I say that? Been there done that. Fanboys think these things are perpetual motion machines. They think all lithiums are the same. They're not, and unfortunately all you kids will see that in a few years or sooner. Only my best cells (Samsung and Sony) have lasted more than 5 years without losing more than 50% capacity. And even them, not much longer.
Let me ask you fanboys a question:
Your laptops, cell phones, power tools, etc that came with quality lithium cells...how many years did you usually get out of the battery packs before they seemed like they no longer held much of a charge, or you were charging them 2 or 3 times as often as when new?
If you say more than three years you are a lying dog-faced pony soldier
So why the f*&k do you think your cheap blue China cells are going to last 20 years? The ignorance, denial, and just plain stupidity of the fanboys here is dangerous when preaching to kids and newbies who just came here for the truth. You think you know the truth, but you don't. You fanboys can't handle the truth.
Let's revisit this video in 5 years. That guy may seem much smarter to you then than he does today.

I just set a reminder for March 8, 2025 on my Android phone. If its battery lasts that long.

If you want to compare LA and their life to a cell phone or laptop. Then run that LA battery in a 100% duty cycle and get back to us. How many 100% duty cycles can a LA battery do, before you have killed it? I know the Lithium batteries in my cordless tools have lasted a lot longer than the Ni-Cads they replaced. I don' think they're some magic bullet. But they're the best we have for the general consumer today. Also the same amount of usable AHs in LA Golf Carts will cost more than I just spent for 280AH of LFPs.
all these stupid engineers in every sector of every market from phones to tools to cars are using lithium. Theyre just too ignorant to know about the superior qualities of lead. Theyll be sorry just wait and see. If I dont know something, then they surely dont either.

Don't play stupid. Phones and tools never used lead. They used ni-cads or ni-mh, and lithium is far superior to them in small devices.
Cars still use a lead starter battery, UPS systems still use lead, and the telecom industry still uses lead. Most applications that used lead still use lead. Lithium batteries are still a relatively new technology that is evolving very fast. It's the wild west out there right now, so the scams outnumber the quality. Since everyone here shops by price alone, it seems, there is bound to be a lot of unhappy buyers.
Some of you just can't comprehend English. I'll say it again....quality lithium is better than lead, but not all lithiums are created equal. We have no idea yet how long those blue cells will last....and I doubt all the blue cells are created equal.

yes probably the same stupid engineers who told us that a plain tungsten bulb is crap and you need a bulb full of non ROHS electronics and tubes that contains mercury to have less light (and bad quality over that) than a tungsten bulb can give. and Oh, the life being a lot shorter also...

I don't know, and neither does anyone else. That's my point.
Winston, Calb, Sinopoly, and maybe CATL at least have some track record we can go by. But even they are evolving and improving often. Batteries made with quality cylindrical cells (cells that have been used in other devices for years), like Tesla or Battleborn, should last a long amount of time. We can only go by what we know, and we don't know anything about these new cheap cells other than the market is flooded with grade C rejects. Anyone who has used a lot of 18650s know there are HUGE differences in quality and capacity from one to another, even though they look identical. And there are 100s of junk brand cells for every good one. Same goes for these aluminum cased LFP cells, I'd assume.
While the solar industry has pretty much decided LiFePO is the future, other industries aren't so sure yet. There is so much research being done right now on other chemistries that charge faster, run cooler, have more capacity and work in freezing temps. I wouldn't be surprised if there's a new flavor of battery out in 5 years.
For those that need storage now, go ahead and buy decent lithiums. Just don't believe the hype about them lasting 4000 cycles or 20 years.
We need more testing data to weed the good from the bad. There's not much out there. Here's one study...check out the problems encountered and capacity losses as these reach 2000 cycles (in a very controlled laboratory environment).
