We get reseller grade A. The best of the EVE rejects. ?
I don't think there is an official definition of Grade A cells.Some further questions if I may...hope their not too simple or repetitive ?
Is there an 'official' definition of Grade A cells vrs Grade B ?
And what qualifies as "Matched" .
similar "balanced" (I presume at same Voltage and SOC, and thus capacity ?)
And re discussion of an initial 'long' charge at 3.65V / =TOP Balance to 3.65V ? .. but its recommended to not do that again ? Are new Cells presumed not to have been charged to that ? used cells one would assume have ?
I did some searching and sent out a Request For Quote on Alibaba looking for a different supplier for 280Ah cells.
I read all about Amy and Xuba. Even with all the guidance, some people still seem to have troubles. Their prices weren't the best, so I ordered my first 4 from UNIS. They work great, but, for some reason, I couldn't get them to send me a new label to replace one that was peeled back in shipping.
Emily from Shenzhen Basen answered my RFQ with an offer of $77.40 per cell. MOQ = 4. She says they are Grade A new cells.
Shipping is $268.00. With the Alibaba service fee, a batch of 16 came up to $1536.53 delivered to my door via FedEx (after they get off the ship).
I ordered two sets of 16.
Now, we wait...
I need help I don't understand the difference between EVE cells and shishen cells . referring to the 280ah cells that are everywhere on Alibaba and aliexpress ?Aliexpress first 105ah I find :

Eve
174x72x205 = 2570cm3 -> 0.109ah per cm3
You see...the 280ah got a lower energy density then the 105ah.. if my numbers are good.
They are all Eve cells. Basen is a supplier just like Xuba and UNIS. They are all in the Shenzen region of China.I need help I don't understand the difference between EVE cells and shishen cells . referring to the 280ah cells that are everywhere on Alibaba and aliexpress ?

Alibaba might give that information on a detailed receipt. But Basen should be able to tell you how to get a receipt that shows VAT.Basen just made me a door to door offer including customs and import VAT. Just about to answer the question, how to get a paper about the paid VAT to apply as a business owner for VAT refund.
Are here some EU citizen with import experience, what sort of paper did You receive as a proof, the import VAT is paid?
I would like to know the answer also ...I tried to find out but couldn't ..I talk to my accountant and importers sped companies. Was also at tax office and they said for vat to work on invoice of company where I purchased batteries also need to be info of EU based company who imported batteries in EU and their tax number and proof that vat was paid by them ...have batteries on the way so when they arrive in 20-30 days I will have more infoBasen just made me a door to door offer including customs and import VAT.
