Years ago I use to use 14.2v absorb and 13.6v "float". For the past 3 or so years just been using 14.1v absorb and 13.6v "float". 14.1v is the lowest I'll go fo the reason my SOC will reset the capacity to 100% whenever the pack voltage reaches 3.49 to 3.52 V per cell on average.
Packs performing just fine. Depending on batteries/ cells and what bms it has might dictate what voltage is needed for balancing of cells and resetting soc capacity.
If someone wants to use full capacity of the batteries or just partial it won't make a difference as long as the cells stay in some sort of balance with a periodic recharge.
Nothing better than individual choices, one size doesn't fit all.
