Figured its time to document my process of buying/receiving/testing these cells
First off: Working with Amy is nice. She responds super quick and gives honest (and true) information
I ordered 32 (8x4) "EVE 3.2V 280AH NEW GRADE A". Here is the timeline of events. Once my capacity tests finish I will put my overall recommendation (yes or no), on the top post...
Status of cells on arrival:
Between then and now:

- 1/31/21 I reached out to for a Quote
- 1/31/21 She replied asking for detailed shipping information
- 2/2/21 I changed my request from 16 to 32 cells
- 2/3/21 I got a new total quote: ($529) shipping to west WA, total cost of ~4300
- Some general back and forwards over a few days as I lingerd on if I wanted to pull the trigger.
- 2/6/21 I payed Alibaba
- 2/6/21 Amy Confirmed
- <Chinese newyear!!>
- 2/22/21 Amy replied said they just got the next batch from Eve, welding studs now
- 2/28/21 Amy said they went into shipping
- 3/2/21 I recieved pics of the cells being packaged, voltage checked, etc (but could not get a test report)
- 3/8/21 *domestic* tracking info provided (doesn't help when the cells are on the boat
- <LOTS of waiting>
- 4/1/21 I asked if she had any info on the boat, she replied with ETA in Cali on 4/4/21
- 4/9/21 I followed up for status
- 4/10/21 Amy replied saying they have been unloaded and cleared customs, waiting on Fedex in cali now
- 4/12/21 Fedex tracking came alive
- 4/19/21 all 16 boxes arrived on my door
Status of cells on arrival:
- Packaging was great. I honeslty think you could have yeeted these off a 50 foot building and they'd likely be un-damaged. Very very nice packaging, double boxed, etc.
- Every cell was 3.295
- No visual imperfections (except one positive terminal is not centered by a mm or two)
- Got 32 busbars and ~70 bolts (32 isn't enough for most uses, I mentioned this to her)
- The bus bars, imho, do not look near thick enough to handle 300A of current. They are ~1/16th, maybe 1/10th of an inch thick, made out of <Some shinny metal?>, and 3/4 inch wide. But Will used these on his 280ah video and seemed OK with them /shrug.
Between then and now:
- I screwed around with the cells quite a bit (hooked up 4 to series to test a few 12v things, hooked up a 48v string to test my Renogy inverter/charger, etc)
- Had to figure out how TF im going to get more busbars. These aren't apparently things in the USA. I contated Amy and she was willing to send more over rush Air shipping for 1.2 per + 33$ shipping
- I bought 18 feet of 1/8''x1'' copper, and made my own busbars
