I bought them last year from 18650batterystore. Works fine. At the time I bought them, I didn't know about the production issues with the LF280k. Don't know if they sorted them out. I'd probably go for the 304 version. $4 (4%) more for 9% more power.

Or grade B 304's from them. Almost 10% more power, $30 less. That's about $500 savings on a 48 volt battery.

Thanks all. What's the difference between Grade A and Grade B - and are those standard across manufacturers or vendor dependent? I presume A is better than B?
Long long ago I use to buy factory blemished batteries at a decent discount - electrically identical and I swear sometimes the "blemish" was a simple overstock. e.g. Call it a blemish to get it sold at a lower price without impacting the primary trade. Is A vs. B something similar?

Yes it's similar.
Manufacture a bunch of cells and the highest yielding cells go to the EV market and are called grade a and are priced for that.

That is a respectable price and they are very correct when they say a proper A-Grade 280K-V3 tests out around 300-305 AH.

Alas I'm USA based, shipping from NL would probably be prohibitive. As would any return issues.

18650batterystore is legit, mostly but recently they are not sending out test reports so because of this I would say wait until they have this problem solved.
If you are after the cheapest grade A and need to buy a good amount: sunfunkits: https://www.sunfunkits.com/productg...ss-certified-prismatic-cell-32v?ProductID=130 that is going to be the cheapest at $98.96/cell shipped & delivered.
They appear to have a 40 cell pallet in the us warehouse: https://www.sunfunkits.com/productg...ss-certified-prismatic-cell-32v?ProductID=141 but price is not as good at $109.35/cell plus shipping.
Right now I'm leaning towards batteryhookup:
https://batteryhookup.com/products/4-new-eve-3-2v-280ah-lk280k-lifepo4-prismatic for smaller amounts the report can be downloaded by anyone and its v3 cells in stock, but expect to pay sales tax + shipping for most places so it ends up closer to about $145.00 cell shipped.
There is also ezealco.com but there toxic relationship with docan makes it harder and harder to recommend; especially when both companies use the same report and then claim they are separate companies...
But yes 18650 is legit, however, do not order until you get a guarantee that you are getting test reports with your order.
