Add to that only 8 sales.The store has been open for only 6 months. open in Jan 24th 2021.
$513 (after discounted) for four 200Ah batteries, that seems a lot.
62% from Sanben were bloated right out the package and tested at 306-314 aH out of 320.It's important to compress these cells. They will bload up immediately, if they're charged without. Will said in one of his last videos, that's because of the thin casing because they're designed to use in automotive applications, where they are fixed in a frame.
Don't know if you are the same person or not, but that is the second QR I have seen for March, 2021 LF280s. Some suppliers are selling slightly older ones, i.e. made in 12/20. Mine were 12/20 production but the three I tested so farhad 286, 287, and 288 amps.I ordered from Sanben, 8 x 280 Ahr cells. Received in good condition. Not swelled at all. Perfectly flat. Seemed to measure as matched. Did a top balance which went very quickly. Load tested to 282 AHrs when configured as an 8S pack with cell cutoff at 2.7 volts. Happy with that order.

This is the QR code on one of the cells. They all had the same date code.

I have recently placed a second order, am a bit nervous, but hopeful. I think we just never know.
As a note, this the 'same' set of batteries is now $1350 from them, not the $1223 shown above. That was the price in June.
I've heard this automotive use a few times, but try as I might I cannot find an EV manufacturer that uses thin wall prismatic LiFePo4 cells. I'm sure if they did there would be plenty of used cells available from dismantled cars, just like the Nissan Leaf cells.It's important to compress these cells.

For sake of options, Basen ships the same batteries as Amy. My set of eight EVE LF280 were all in perfect physical shape, all were IR=.17, and capacity tested 286-288 (out of 5 tested so far). It was cheaper to get my EVEs from Basen in the US with one week delivery than waiting for cells from China. Glad I found Basen as I am thrilled with what I got and the service, not to mention having them in a weekI received SLT/Amy’s 280 aH batteries and they were all flat or slightly concave, voltages within .001 of each other, IR= .18-.19 mOhms. Great condition. Capacity tested at 284 out of 280 aH, 25A discharge from 3.65-2.50V. Wonderful.

Check out David Poz's videos where he dismantles BMW, Volvo, and Chevy battery packs. Not a thin wall prismatic cell in any of them.
And how would you cool prismatic cells if they were clamped together in an EV?
And this looks like another too good to be true store.
