You used to be able to drill and tap them but that is no longer allowed by EVE...
lol yup... until He shows evidence for his opinion with long term comparison testing its just an opinion. hes not even compressing them correctly at all there showing his bias regardless. until I see some actual long term testing showing it doesnt effect capacity as well as cycle life I am just as inclined to believe it might.
Not so long-term testing and he confessed that he was likely wrong.
Have you seen such information for a LiFePo4 cell? I haven't seen this detail in the EVE/CALB datasheets.but even that is likely to exceed the calendar life expectancy of the cells.

PVs actually say that they will fade X% in 25 years. It would be nice if the same was available for the cells.
So more recently he seems to believe the compression matters now... I agree he is learning and I totally respect that as we all learn as we go and make mistakes. But hes quick to form and share opinons based on incorrect assumptions like the series he did bashing the JBD 300amp relay bms that he himself damaged by changing setting incorrectly and causing the relay to quickly cycle on and off over and over bypassing the cooling time mechanical relays need to prevent burned and fused contacts. He then went on to explain those setting and the presets made no sense which to me made it clear he thought the mechanical relays could switch on and off quickly like mosfets with no tradeoffs. I love watching his stuff and value his input but I think he could benefit from being a little more cautious about what he tells people from time to time. He is quick to blame things.You need to watch that with more attention. He doesn't admit that he was wrong. He shows that his cells have expanded and it might be stressing the terminals.
At about 7' he assesses the swelling and considers it to be not that bad and refers to another youtuber who had restrained his cells and got the same swelling even though the cells were restrained.
IOW it's a click bait video title.
My understnding of his thoughts on restraint aren't that you shouldn't do it but that, in low current applications, the effect on cell longevity is pretty much irrelevant - you might only get 3000 cycles instead of 6000, but even that is likely to exceed the calendar life expectancy of the cells.
Is the EVA foam shown in the video provided by Seplos, or is that something that Andy added?So more recently he seems to believe the compression matters now...

That is why I asked. Do any of you Seplos owners care to answer?foam is not a good separator material should be fiberglass sheets.
Oh how this thread has aged. We expected to see the B markings on cells. Now the Chinese has one upped their game and started sanding off the original QR and printing a new one on it. And then sell it as Grade A.
seplos provides it for their mason kits by default, but you can purchase it through alix tooIs the EVA foam shown in the video provided by Seplos, or is that something that Andy added?
it isnt just foam...foam is not a good separator material should be fiberglass sheets.
Thanks. Andy specifically mentioned EVA in the posted video. I'll surmise that he added it himself without reason or any sort of properties measurement on his behalf.it isnt just foam...
and no , it should be fiberboard, as that will not allow for cell movement
no, he is using the sheets provided, but next to a "squezy" eva side, there is a added thin plastic seperator behind the glueThanks. Andy specifically mentioned EVA in the posted video. I'll surmise that he added it himself without reason or any sort of properties measurement on his behalf.

Your two answers were confusing. Thanks for getting me straight.he is using the sheets provided
