Incorrect... a charging source of 14.2V and like an alternator will get LI's to 100% SOC, and as efficiently as a source of 14.6V due to their very low internal resistance as compared to lead acid batteries.I can't tell you much about solar charger settings - I don't have solar and haven't researched it too much. But what does your battery company say about charging? Mine says that the battery rest voltage at full charge is around 13.4, and they recommend CCCV chargers with a charge voltage of 14.6. So setting your absorption mode to 14.2 is similar to charging from the alternator (mine puts out about 14.2) - won't get the battery to quite 100% SOC but will get it close. It also makes sense to turn float off - I haven't read anything that recommends float for lith batteries. More detail than this - I can't even begin to guess.
