Cell ordering journey

[Jimmynik1]

Just placed my order and wanted to document it to potentially help any others looking to order in the future.

I ordered from Minji Guan who works for Dongguan Billion Electronic Technology Co., Ltd.

My order was 16 310 cells with 2 8s150a daly bms with bluetooth.

The total total including ali's fees was $2539

I placed the order on 8/6 and was given tracking on 8/13

This is the link to the tracking.

Three of the boxes are the same weight and the fourth is heavier because it likely has the bms in them.

This is the link to my cells.

Hi
How was the experience? Were the cells good quality?

I need high discharge cells for my robotic platform and settled on Eve LF90k cells. The same person(Minji Guan) is offering them for 33 USD each, While EVE official Store on Alibaba is listing them for 65USD. He claims they are grade A Original eve cells.

Should I buy a 12s 90Ah pack from Dongguan Billion or should I get a 10s 50Ah pack from EVE (Same price)? Any help appreciated.

I also bough from Dongguan Xinfang , 16 cells of EVE LF280K . But it seems there is a sticker with a QR code on top of the original QR code . This seems very alarming .

Unfortunately it is impossible to remove this sticker ...

Also while I am top balancing all the cells in parallel to 3.65 V it seems some of them are getting slighly bloated .

Any ideas of what it might be , is this normal practice now ?

Ohh FACK man, I heard of people doing this but I was like meh they probably not going to go through the hassle but clearly this is now a fact:
