Unexpected current/voltage step with Multiplus 12/500/20 while charging LiFePO4

Hi everyone,

I set my Multiplus 12/500/20 to LiFePO4 charging curve yesterday when I replaced my former AGM with my new LiFePO4 (integrated BMS) in a camper van. Now I just had a look at the overnight charging curves and I am a little bit curios what triggered this current/voltage step? I would have expected the current to go down to ~0Amp continuously without interruption.

Any suggestions? Help is much appreciated and therefore thanks in advance.

@Thorben it looks like a load cut in, diverting current away from the battery.
