Quattro LiFepo4 Charge sequence

I have selected Lithium batteries in the VE Config 3 and LiFePO4 in the following battery type panel. An explanation of the settings appear in a pop up table.


I have watched the charging process:

Bulk = Constant Current, with voltage steadily climbing towards 14.2V

Absorption = Current reducing and voltage nears 14.2V

14.2v and current down to 10A


My question is when does the Quattro switch to float (13.5V)?


I realize that the terms Bulk and Absorption are not applicable to LiFePO4, perhaps Victron could change the headings to "Charging" & "Float" in a future update

I had this advice from a very helpful victron tech in Australia.

basically the Quattro switches to Float after being in Absorption for 1 hour. No science, no "Smart' profile just 1 hour

if I had looked at the data panel it does say "Max Absorption time = 1 Hour"
