LiFePO4 is a subset of lithium-ion chemistry. Li-ion also includes nickel-manganese-cobalt, nickel-cobalt-aluminium and others.Quote:

As for car type accessory batteries of the LiFePO4 type, I found this video interesting.
They talk about construction and durability when it comes to off-roading, amongst other things ...
LITHIUM VS AGM BATTERY for Overlanding. Should I spend the money? - YouTube
(noting it's 2 years old, so pricing is out of whack, and IIRC, lead-crystal gets a mention)
Hi Redtail and just be aware, the guy in that video is a moron and has no idea what he is talking about.
The video is full of misinformation and just out and out B/S.
If you are seriously considering going to Lithium batteries, you need to become a bit of an expert on the subject first, because most lithium battery sellers have business morals equal to that of an alley cat on heat.
If you are watching these types of videos, the first warning is when they claim you can not take a lead acid battery, be it folded or AGM, below 50% SoC .
This is total crap and there is no battery manufacturer that states anything like that.
Most state their batteries can be cycled down to 20% and a number now state their batteries can be cycled to 0% SoC.
Again, YOU need to become the expert.
LTO batteries are making headway
22000 cycles down to near 0%
a tad expensive though...
Now I'm curious! Which one's the moron? LOLQuote:

But let me say, having had that discussion, it would be a totally uneconomical and pointless move to lithium for my situation and needs right now.
(Should I change out the car in the next two years, lithium would be a no-brainer, IMHO for many reasons. Again, keeping an open mind until it's time to do so.)
I like to think I do my background research by checking facts when I'm looking for gear and design.
(Having a tame chemistry teacher in the household is quite useful, too.)
Getting back on topic as far as this post goes, I noted the remarks about the battery's physical construction and it not falling apart after 1,000km of corrugations.
This made some sort of sense, having seen a brand new starter battery fall apart on a trip a few years back.
Thanks for the heads up.
I shall endeavour to remain scientifically skeptical!
Our caravan came with an Enerdrive package including a 200amp lithium battery, 2000 watt inverter and 40amp DC-DC charger.
It all works very well.
The research I did suggested the Enerdrive gear is good quality.
The caravan company said they find Enerdrive good to deal with.
Enerdrive have a good YouTube set of videos and an active help line.

Commercialization and advances[edit]
The performance and capacity of lithium-ion batteries increased as development progressed.
- 1991: Sony and Asahi Kasei released the first commercial lithium-ion battery.[39] The Japanese team that successfully commercialized the technology was led by Yoshio Nishi.[40]
- 1996: Goodenough, Akshaya Padhi and coworkers proposed lithium iron phosphate (LiFePO
4) and other phospho-olivines (lithium metal phosphates with the same structure as mineral olivine) as positive electrode materials.[41][42]- 1998: C. S. Johnson, J. T. Vaughey, M. M. Thackeray, T. E. Bofinger, and S. A. Hackney report the discovery of the high capacity high voltage lithium-rich NMC cathode materials.[43]
- 2001: Arumugam Manthiram and co-workers discovered that the capacity limitations of layered oxide cathodes is a result of chemical instability that can be understood based on the relative positions of the metal 3d band relative to the top of the oxygen 2p band.[44][45][46] This discovery has had significant implications for the practically accessible compositional space of lithium ion battery layered oxide cathodes, as well as their stability from a safety perspective.
- 2001: Christopher Johnson, Michael Thackeray, Khalil Amine, and Jaekook Kim file a patent[47][48] for lithium nickel manganese cobalt oxide (NMC) lithium rich cathodes based on a domain structure.
- 2001: Zhonghua Lu and Jeff Dahn file a patent[49] for the NMC class of positive electrode materials, which offers safety and energy density improvements over the widely used lithium cobalt oxide.
- 2002: Yet-Ming Chiang and his group at MIT showed a substantial improvement in the performance of lithium batteries by boosting the material's conductivity by doping it[50] with aluminium, niobium and zirconium. The exact mechanism causing the increase became the subject of widespread debate.[51]
- 2004: Yet-Ming Chiang again increased performance by utilizing lithium iron phosphate particles of less than 100 nanometers in diameter. This decreased particle density almost one hundredfold, increased the positive electrode's surface area and improved capacity and performance. Commercialization led to a rapid growth in the market for higher capacity lithium-ion batteries, as well as a patent infringement battle between Chiang and John Goodenough.[51]
- 2005: Y Song, PY Zavalij, and M. Stanley Whittingham report a new two-electron vanadium phosphate cathode material with high energy density[52][53]
- 2011: Lithium nickel manganese cobalt oxide (NMC) cathodes, developed at Argonne National Laboratory, are manufactured commercially by BASF in Ohio.[54]
- 2011: Lithium-ion batteries accounted for 66% of all portable secondary (i.e., rechargeable) battery sales in Japan.[55]
- 2012: John Goodenough, Rachid Yazami and Akira Yoshino received the 2012 IEEE Medal for Environmental and Safety Technologies for developing the lithium ion battery.[26]
- 2014: John Goodenough, Yoshio Nishi, Rachid Yazami and Akira Yoshino were awarded the Charles Stark Draper Prize of the National Academy of Engineering for their pioneering efforts in the field.[56]
- 2014: Commercial batteries from Amprius Corp. reached 650 Wh/L (a 20% increase), using a silicon anode and were delivered to customers.[57]
- 2016: Koichi Mizushima and Akira Yoshino received the NIMS Award from the National Institute for Materials Science, for Mizushima's discovery of the LiCoO2 cathode material for the lithium-ion battery and Yoshino's development of the lithium-ion battery.[58]
- 2016: Z. Qi, and Gary Koenig reported a scalable method to produce sub-micrometer sized LiCoO
2 using a template-based approach.[59]- 2019: The Nobel Prize in Chemistry was given to John Goodenough, Stanley Whittingham and Akira Yoshino "for the development of lithium ion batteries".[60]
- 2022: Battery startup SPARKZ announced plans to convert a glass plant in Bridgeport, WV to produce zero-cobalt lithium batteries.[61]

What interesting in that list is 2001 Dr Jeff Dahn He is now working for/with the company NOT the one Solid state battery one that paid for my EV[thumbsupbig]
"Jeff Dahn is the Chief Scientific Advisor to NOVONIX Professor Jeff Dahn is a leading researcher in the field of lithium-ion batteries and materials and currently holds the title of NSERC/Tesla Canada Industrial Research Chair with Dalhousie University"
The time frame, Commercialization and advances for the next gen is helped I think by the sheer brute computing power now available to test and simulate models of new tech
Some might have heard of him? Try "In 2019, Jeff Dahn was among the first people to suggest that an EV battery might last for one million miles before it needed replacement. Today, he and his researchers have published a paper in the Journal of the Electrochemical Society that suggests a battery that can last for 100 years is possible. The paper has the rather engaging title of Li[Ni0.5Mn0.3Co0.2]O2 as a Superior Alternative to LiFePO4 for Long-Lived Low Voltage Li-Ion Cells. It’s a page-turner, to be sure, and anyone who chooses to delve more deeply into it is welcome to do so"
New syntech Graphite is of double interest to me due to Hazer Hydrogen in WA which spits out two tonnes of Graphite for every tonnes of Hydrogen

Battery changes are both extremely fast and slow
Not investment advice just my interest in time frames :)
