Assistance Interpreting LiFePO4 Test Report

[Xhumeka]

I think I would be able to fully understand this chart if it was in English, but I'm having a hard time interpreting the results from this test report I received for cells I ordered from Eric Wang of "Shenzhen Hongxinda New Energy Co., Ltd.":

Would someone mind assisting and give me the "Coles Notes" of this report? Thanks!!

Looks like they are showing a capacity test (shows 95-100AH's) then a recharge to about 30% in preparation for shipping cell.

1) charged to full, put in about 77.7 AH's of charge to full 3.65v at 30A. Held at 3.65v until current taper off.

2) discharged at 20A until 2.58v cell voltage reached. About 4.75 hours at 20A's for about 95-100AH.

3) Recharged to 3.28v and allowed to current taper down. Put in 22.33 AH's.

Thanks RCinFLA!

Why they just don't have a seprate charge curve and discharge curve? I have this same tester and this combo/discharge makes it a PIA to see.

So I made a profile for charge and a sperate profile for discharge.

Beautiful curves for both and clear and easy data.

I think for anyone buying a bunch of cells the ZKE is an excellent investment. Also many people have compared it to very expensive testers and found it is very close to there readings.
