I just completed testing 36 EVE 280AH cells purchased in the Group Buy thread.
Tester: https://www.aliexpress.com/item/32821857011.html
Wire gauge increased to 10. Connected to cell via lugs (in other words - a high quality connection, not the alligator clip method).
Amperage: 15
Temperature: 60-70F
Starting voltage: 3.65
Ending voltage: 2.2 at the tester, ~2.5 at the cell
The IR on all cells measured at 0.20 at 15 amps at the start of the test.
I am confident in the tester as the results line up with multiple shunt readings while the cells were in a battery, including Victron BMV-712.
I wanted to post this front and center so it's easy for everyone to get at this data.
