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 ...

It seems like you're confusing my post with Don's, I didn't say anything about a "calendar-scheduled approach…".
The Battery Management System (BMS) in all LiFePO4 batteries has a cell balancer built into it and it works every time the battery is charged completely. Some batteries (like Battleborn) need an absorption stage to give the balancer more time to work; they typically only balance at 500mA so it can take awhile. Its transparent to most battery owners unless they have a BMS that displays battery cell voltages.
Its all in the specs of the battery you buy, if it doesn't say anything about an absorption stage then you don't need one.
