I was simply responding to MattsAwesomeStuff's silly statement about LFP being "antiquated and problematic"
You're right, I was unaware of these new cells ... which aren't available to the DIY market, which is the relevant context anyway.
I think it was Duncan who pointed out that literally every single DIY build that used large format LFP cells that ever reappeared here had multiple failures after a few years, and that literally zero people who'd used OEM batteries has had a failure.
Naturally a casual forum observation is not the strictest of scientific methods, but, regardless of whether it's literally true or just generally, and, seeing as how I haven't heard of anyone using LFPs in years unless they were built around that expectation from years ago, I stand by my assertion that LFPs are antiquated and problematic.
All things being equal, they last 10x longer than the usual 3.6 - 3.7V li-ion chemistries
I think you'd have to fudge your data pretty heavily for that to be true. In DIY EV context, it certainly seems that either all things aren't equal, or, they're massively failure prone.
it is not the 16S (60 V) 43 Ah module used in the Chrysler Pacifica, and not even built of the same cells
My bad, I was too lazy to look it up, presumed these were the cells that were all the rage a year ago that have since fallen off the map.
MattsAwesomeStuff, so if all of those aren't usable, what would you use?
They're usable (except for the ones you can't actually buy anymore). They just come with compromises you have to work around.
In addition to your list, Leaf and Volt packs are still popular, because of their smaller form factors (avoid or be careful with 1st gen Leaf packs, they suffer from degradation issues).
You're generally not going to be able to fit a whole 96s pack into a vehicle not designed around the size and shape of the batteries you pull out of an OEM EV. Like fitting soup cans into a rubbermaid, it's just not going to pack as nicely as the original box. Which means you're not going to get the same top speed or performance out of vehicle as the original. To many DIY EVers, that's perfectly fine. They're not in a racing or performance mindset. They're in a "build a fun car that can quickly reach legal highway speeds and casual driving range."
