Yes those are the latest version, likely better than the below, as per older "A" model.
Stored in coolish conditions at 50% SoC isolated / no charge / no load will lose maybe 10% capacity at most over twenty years.
Cycled between resting 4.35V as 100% and
avg 80% DoD
below 1C current rate
maximum LVC 3.1V as 0% DoD only occasionally
charged at 0.4-5C in warmish temperatures
will go 7-8000 cycles, EoL defined as 70-75% SoH.
> Do you have any data on your claims?
Nope, there are a dozen variables that impact longevity, they all interact with each other, industry is focused on high-C rate EV type applications where they "only" last 3-5000 cycles.
> Also how do they perform at very low temps vs the others in this thread?
If by very low you mean in 0°C territory, the only LI chemistry that stands out is LTO, real odd man out.
With all the rest including LFP, charge rates need to **drastically** get reduced as 0° is approached
fast charging in freezing temps can instantly render the whole bank scrap.
Active warming is often implemented as needed, for very fast charging even to 35-40°
Discharging in cold temps does not cause damage, but rapidly becomes slower and much less efficient, as with old-school lead banks.
