when should a powermax pm4b drop into float mode

"The threshold you talk about is probably the inflection point where Bulk ends and Absorption starts. At this time the voltage has risen to the max set point and the amps just start to taper. Converters can make this confusing because they may drop voltage at this point. Some portable chargers may increase voltage at this point. Still the same process, charging curve is just different."

yes, this is what i was referring to.
