The new cells which Luyuan is selling are direct from EVE
not from battery brokers. Amy has negotiated Direct Supply Contracts with the companies and that means no "new old stock" or 3rd party stuff. *Even the QR Codes reflect the difference as they have cell ratings on them.
New (Matched) EVE-280AH/896Wh cells - Photo of one which I received from Amy @
Luyuan Tech Link to 280AH cell page.
The laser welded Lugs on the cells are quite a bit nicer than having to deal with bolts, grub screws etc.

There are two classes,
The Matched & Tested @ EVE Factory, cost more obviously but still a good value. If a 3rd party was to do such batch testing, it typically costs 50% of the cell cost which is added to the price. See QR Code shown for a Matched Cell.
Matched & Batched cells will charge & discharge at equal rates and will remain in balance far better over their entire operating range.

<--- Bulk Commodity cells which are still Grade-A but not matched and usually on the edges of the Grade Spec.
Unmatched cells will deviate and most often will have Runners which will either reach discharge Lo Volt Cutoff or Hi Volt Cutoff before the other cells limiting the overall capacity of the battery pack. Bottom to Top Charge & Balancing can address some of that to "a point". A Good Active Balancer can also mitigate some of these issues but it's not a perfect solution.
FYI, CNY (Chinese New Year) has just ended and all the Chinese businesses will be back to "Full Throttle" by the 1st of March, expect at least 2 weeks delays on things due to backlogged shipments & orders and of course any Covid Related delays at the shipping & receiving ports.
SHIPPING TO UK can be tricky since Brexit and things being sorted, never underestimate bureaucratic stupidity, they always find a way to mess things up. Contact ANY Vendor directly on Alibaba using the messenger / chat facility on the webpage. The Shipping Guesstimators are only sample shipping rates.
Hope it helps, Good Luck.
PS: Before anyone asks how I got mine so quick, the last batch was by Air-Freight (ouch $) and UPS even screwed that up.
