I seem to have an issue that I can’t find much information about on the internet. I recently purchased a EBC-A40L on Amazon. Upon setting it up and running some tests on a LifePo4 cell, I noticed when doing a charge test CHG-CV I am unable to get the Cutoff Current to go above 9.99a.
Example:
Using the buttons on the tester, when I’m doing a charge (CHG-CV) I can set the charge current (30a) and the constant voltage (3.5v) without issue. But I am not able to get my cutoff current to go any higher than 9.99amps.
I’ve also tried the computer software and have the same issue. On the EB Tester software using the single test window, I set the charge current to 30amps, then the charge voltage to 3.36v, then the cutoff current to 29a. When I hit start the cutoff current changes to 9.99a on the screen and during the test when my voltage reaches 3.36v the charging will continue until the current goes down to 9.99a then it will cut off.
I have tried 2 different versions of the EB Tester software v1.8.5 and v1.8.8 and both have the same issue.
When I power on the tester, I show I am running V3.0.3 firmware, but my startup screen does not say ZKETECH on it like I've observed on some other videos on the internet.
Thanks in advance for any help anyone can provide.
