I would not want to float an LFP above 13.4 volts. 13.2 - 13.3 is better. I don't know anyone that recommends holding LFP long term at 100% charged.
14.6 is also higher than necessary and is more likely to cause a fault in some lower cost brands from CN that many look at.
This generally gives the standard PD or the PowerMax with adjustable voltage an advantage. Both drop to 13.2 volts for long term.
That is my opinion. Good luck to the OP.
