What is the delta peak? I mean, the delta peak is the same in every Imax?.
I put, now, 0,5 amp and the cell started warming up
However, the Imax show 1,57v (charging) and didn't stop yet. Is it normal?

First, I put low current to not damage the cell (low current is better than high current).
I decided to discharge them fully to charge them fully, to know the exactly capacity...
