But, I'm getting off the subject.
lifepo4's not needing absorption---that was the lifepo4 charging philosophy a 2-3 years ago when nearly all lifepo4 converters/chargers were single-stage 14.6v (no absorption or float stage).
More to my point . . . if a standard lifepo4 (lithium iron phosphate) cell (with a typical 2.5v LVD and 3.65v HVD) is used by a battery manufacturer, and the manufacturer recommends only bulk charging at 14.6v, I assure you they're recommending this at the expense of cycle life. Charging a lifepo4 cell at 3.65v (Maximum Rated Charge Voltage), or a 12v lifepo4 battery at 14.6v, 24/7/365, will reduce cycle life short-term, and permanently damage the cell/battery long-term.
