My Blue Smart IP65 25A gets interrupted during the charge of a LiFePo4 (Li-Time 12V/100Ah) in the Absorption Phase. This is because the nominal charge current only drops for a very short moment (appr. 20 sec 25A down to 18A) in the Absorption Phase before the internal BMS cuts the circuit. The battery goes back to full charge current for a few seconds for a couple of times before it finally stays with 0A. The charger status is „interrupted“ and it can never find an defined end. I confirmed the charge behaviour with a laboratory power supply at 8A charge current and I confirmed the battery reached full capacity with an electronic load.
So the question is: Is there a setting that would accept a very short „Absorption phase“ and the charger would come to a defined end?
