14.7v regulator would be on the high end of what an AGM battery will tolerate. sulfation/batt life would go down, capacity would go up... you are better off under 14.2v for longer life.

for a few months during testing for Shorai LFX 21 .. determined actual AH capacity was too low for R80G/S when combined with cold weather/heated gear/short trips. a higher output voltage regulator 14.4v-14.5v was tried ... conclusion was one still needed a larger AH capacity battery. but overcharging risks increased during extended rides. switched back to OEM voltage regulator. technically LiFePO4 reaches full charge at 14.6v, so 14.5v would still be under threshold. too close to LiFePO4 limits for extended rides...

this document is worth reading ... contains information specific to AGM 12v batteries. PB chemistries are well established technologies with a voluminous amount of information out there. key is knowing which set of technical information to drill in on.
