Effect of no absorption on LiFePo4?
I bought a low end 100Ah LiFePo4 a couple of years ago. The manufacturer only listed charge and float voltages on their spec sheet. Later I asked them about absorption and they told me 14.4v. They ...

Charging to 14.4 on any regular basis as described by the OP is sufficient to keep the cells balanced. There is no recommendation to periodically change the charging cycle for balancing. Yes if the battery is short charged to 13.6 or less it may or may not get any balancing from the BMS. Could go years like that without issue. The primary time balance can be a critical process is when the battery is first assembled to verify the cells are at the same level to start with.
X2….Mythology has it that LFP’s are in someway ‘fussy’ to charge when in fact (except for cold weather charge constraint) the opposite is true…
OP suggest he may have ‘damaged’ his batteries (how so??)…The basics are, don’t exceed 14.6v, don’t equalize, float at or below 13.6v (or not at all), don’t leave on charger for an extended period of time (say, once fully charged), no need for a full charge except for occasional cell re-balancing and (if applicable) SOC meter resynchronizations…
Applying this basic charge regime is a minor price to pay which negates conventional battery maintenance and achieve faster charge recovery times and a far deeper depth of discharge..
