when should a powermax pm4b drop into float mode

Put the lid back on and now you have a good 75amper charger that has Vabs of 14.8. (You no longer have a "four stage" converter. ) You are now in charge of shutting it off when you figure the batts are high enough. No automatic shut off. 14.8 is too high as a Float except at the North Pole in winter.(end quote)

...so no more auto float mode?

won't 14.8 cause excessive gassing?
