See my reply to you in the other thread. In short, let's wait on valid data before we jump to conclusions on cycle life. It's ultimately moot; time will kill either cell type long before cycle count does.Also, the EHW5/EHW5B series cells are the only ones with the crazy lifespan. Those are the cells you want, for longevity sake. Not the Panasonic Insight cells, as @mudder is quickly noticing in his testing when he says "capacity decreases ~5% after ~QTY600 cycles". That's HORRIBLE compared to the EHW5 cells.
Yeah and I mean 600 Cycles is probably 1 or two cycles per week for me... even with the hypothetical prius AC, age degradation might even outpace cycle degradation.See my reply to you in the other thread.

My rational stems from your previous statement:Not sure why you'd say that?
When I made this statement, it was unclear if you were going to stick around this forum.I can say with 100% certainty that the Insight modules are NOT ehw5 cells. And no, the W doesn't stand for welded. I plan to make a post in the "47AH fomoco" thread to straighten up several misconceptions you guys seem to be perpetuating on this forum.
Not sure why I'd help you, though, after the way you've treated me in a few threads so far.
I 100% agree. I probably do less than 2 cycles per week... So QTY1000 cycles is ten years. I can live with 5% cycle-related capacity reduction over a decade... age-related capacity is certainly going to be higher.Yeah and I mean 600 Cycles is probably 1 or two cycles per week for me... even with the hypothetical prius AC, age degradation might even outpace cycle degradation.
We need to decide what the term 'continuous' means in this instance:From what I can tell, the EHW5 modules are rated for 300A, while the G3 cells are rated for 375A instantaneous and 150A (30c) continuous. The Cmax cells are rated at 100A continuous and 150A instantaneous.
Does that sound right? I'm just piecing this together from information online.
Just curious, as I had read that previously at some point. Seems odd Honda would sell their modules to a competitor (Toyota)... but obviously if they don't own 50% they don't have any say in who they sell modules to.Yes, why?
That's honestly insane. You could not feasibly even do this much in a day. Drain the pack sure. But charge at the 10kw, uhh no.5AhG3 cell just broke QTY1000 cycles:

We've now charged and discharged 15 kWh through this single cell. That's equivalent to 720 kWh cycled through a 48S pack... which is equivalent to a non-MIMA car requesting continuous [email protected] kW for ~3600 minutes AND also continuous [email protected] for ~4300 minutes.
-you drive five days per week, 52 weeks per year.
-each day you use the equivalent energy consumed in four minutes at full assist/regen,
-QTY1000 cycles represents ~3.5 years of driving.
-after 3.5 years, cycling has decreased your cell capacity -3.5% (-175 mAh).
Note the slope has decreased (good):
[email protected] cycles, the per-cycle linear reduction was -222 uAh/cycle (averaged across all cycles)
[email protected] cycles, the per-cycle linear reduction is now -194 uAh/cycle (averaged across all cycles)
47 Ah FoMoCo cell:

Note the slope has decreased (good):
[email protected] cycles, the per-cycle linear reduction was -6 mAh/cycle (averaged across all cycles)
[email protected] cycles, the per-cycle linear reduction is now -4.7 mAh/cycle (averaged across all cycles)
FYI: As mentioned previously, these lithium cells are heavily influenced by ambient air temperature. Today and yesterday were fairly hot, whereas the day before it rained in the afternoon... you can see how much it cooled down on the local maxima that was a trough in it (around cycle 85).
FYI: The 5AhG3 cell is less affected by temperature, likely due to how much warmer it's getting by itself (due to its smaller ampacity).
