That's the difference between 14.4 and 13.6
Note the 20A 'smart' charge @ 14+v exceeds the 13.6v/35A wfco.
What does East penn suggest, 30% of C20 or 150*.3 = 45A
45A charge until battery V = 14.7v
hold 14.7 @ battery for hrs
float 13.8v

there is always this from PD, fast means high current to 14+v, hold 14+v
14.4v boost, 13.6 'normal', 13.2 float
WFCO theroy of operation:
"If the converter observes no significant variations in current draw for approximately 44 continuous hours, it will drop the output of the converter from 13.6V to 13.2V."
Ask why 44 hrs before float.
east penn states c/20 --- 20%... The 30% is for a monoblock design.
Those charts above , wfco vs 20 amp charger, mean nothing IMO as anyone can make a chart.. I would need testing data to prove anything...
