Looks like shipping per cell drops a fair bit once you go from 16 to 32 cells.

I see Amazon sells EVE 280k LiFePO4 cells. Seller is HiXMi. 429 USD for four cells plus shipping.
Has anyone bought these? Comparison to what Luyuan is offering?

Docan offered me two versions of the EVO 304ah cells. EV Grade and ESS Grade, also a MB31 type.
Not sure what the difference is?

I think there is a thread around here about MB31 swelling. I'm happy with 280's probably go with the EV grade I don't know what they mean ESS grade is that considered Grade B. Jenny Wu sent me a spread sheet of tested batteries the QR codes did work on the QR code checker. She sent me pictures of the QR codes that matched they were the ones that showed up. I need to get a shunt to know for sure how many amps went in. $43 is temping but I asked her for a quote on the same type she quoted $949 something like that including shipping that comes out to $60 range I think I got the EV grade. Never know what will happen if one fails I have heard that she will send another one to replace not sure if that is true. Sending anything back to them will cost more then the value of the battery.

That would maybe make sense, ESS could be a new marketing term for B grade. I will go EV. Do you think it's necessary to get the QR in advance? I'm working with Jenny too.

Kilo's cost money to shift about. 280K is 5.6kg each.

I've seen previous quotes from Docan with free shipping, or 40$ shipping for the whole order of 16 cells.
Some vendors get creative with shipping and pricing, so it's a valid question to which I received a smart ass answer

Notice how the price is higher than the earlier quotes for these cells ($85 vs $70). That's because shipping has been factored in.
My response was not intended to be a 'smart ass answer' by the way; just some humor.

Your answer was informative, thanks. It was the next answer that was useless and created more noise than signal in the thread.

That cart works for the US landed cells that include free shipping from Houston. To get the prices ex China including DDP you have to contact them with your address and they'll get back to you with a quote.I've seen previous quotes from Docan with free shipping, or 40$ shipping for the whole order of 16 cells.

I just priced the EV quality lf280k v3 LiFePO4s at Docan for $74 each, which includes shipping to my California address. Wonder if that lower Sept quote is for U.S. delivery, or are the prices going up? As I consider ordering 16 cell or more, also wondering if EV quality means flat sides? I have ordered 3 sets of 8 x EVE 280 ah that were called grade A, and none of them have complete flat sides, as there seems to be minor bulges or slight dips in the sides of most battery cells. Wondering: What are people seeing in their received v3 EV quality LiFePO4 batteries lately? Does EV quality from Docan mean flat sides that I would expect for a Grade A LiFePO4 ? or maybe not? ... Just Wondering :+)

totally flat sides will never happen in my opinion. the aluminum case cells the walls are just too thin to self support. they are basically thick enough to keep the fluid from leaking out and no more. (this is not the same as swelling)

For one, there is absolutely NO SUCH THING as "Perfectly flat" prismatic cells. The jelly rolls within always leave 2 very slightly raised bumbs. The basic is very thin aluminium, similar to an American Pop Can. At present the LFP cells have pretty much bottomed in price and not likely to drop further (of any significance). NO COMMENT on Docan and "EV Quality" cells from them. FYI, These types of Prismatic Cells are "not" used in current EV's, it isn't 2015 anymore.
