Unless these tests involve the vehicle they were designed in, being tested on the road, I wouldn't sweat it. You can make or break anything in a controlled environment.

Knowledge of precisely what breaks them can be applied to their use within the vehicle to determine "best" practices for longevity. Hence his comment about small charge deltas and try to keep under 45C (easier said than done in the SW).Unless these tests involve the vehicle they were designed in, being tested on the road, I wouldn't sweat it.

Maybe you missed taking the time to read his bio and posting history.Did I miss any parts?
For those that asked, my interpretation of this is the delta he is talking about is the charging difference (ie cycling the battery from 10-90% is a larger delta than 40-70%).I will say that the delta is a HUGE issue for this cell
Are your comments generically about raw cells, or vehicle-specific packs with cooling and BMS?I will also say our testing takes us outside of what the truck allowed during our road testing. Do not expect me to make any more post about this specific cell, but I will entertain generic questions based on my 13 years of experience on testing a wide variety of cells
I was under the impression that "delta", when talking about battery packs, referred to the variation in state of charge between individual cells in a pack, particularly when under load.For those that asked, my interpretation of this is the delta he is talking about is the charging difference (ie cycling the battery from 10-90% is a larger delta than 40-70%).
W = A x V, our battery is supposedly 400V, but maybe your car scanner gives a different number?Mickey's the expert and I will be the first to admit that the plural of anecdote is not "data", but I have 53k miles on a 23 platinum. Just ran FDRS battery diagnostic and the pack is still showing 100% health and a capacity of 396.4 Ah...whatever that means.
This is the only useful and understandable post in this thread full of 3 pages of questions and non-answers or vague answers.Mickey's the expert and I will be the first to admit that the plural of anecdote is not "data", but I have 53k miles on a 23 platinum.

Actually I think he said he was going to keep it for a while because 8 year warranty was good enough, but also that their tests exceeded the conditions that the truck's BMS would allow, so the batteries might last longer than his tests imply.Really perplexed about this post. The tldr seems to be
“I’m a battery expert and the battery Ford uses sucks and I’m selling my truck before the battery warranty expires. Please don’t ask me questions as I’m an expert and I can’t share any info”

Your calculation is close to the battery sticker on the side of the 2022 packs.changes our calculation to 146.7 kWh which is still better than it's supposed to be
