Battle Born Charging
This might answer some recent questions. The table is not accurate wrt to the BB comments--don't go by it by the table itself. Wade through the questions and answers to get the true picture. Tak...

"But are you sure you don't reach 14.4volts much later with the Li ?"
You reach the end of Bulk with max charger rated amps still flowing (charger is current-limited) and then amps just start to taper.
So still lots of voltage drop between charger and battery at those high amps. Makes no diff what kind of battery it is.
You will only see the battery at the same voltage as the charger when amps stop flowing. You will only see 14.4 at the battery when the charger is still on too. So for your purposes, you will not be looking for the battery to reach 14.4 at all--that advice in their blurb is just silly. You have to use the start of amps tapering as your marker for when Bulk ends.
Li can take high amps to a high SOC as one of its features. Nobody said AFAIK that means Bulk starts later at a higher SOC. It can mean that amps stay higher during Absorption.
With lead acid batts, a higher charging rate will make Bulk end at a lower SOC at the same absorption voltage. Probably the same way with Li- where you are using a very high charging rate of 50% or more. I would expect Bulk to end sooner from doing that with Li too, but do not have any figures for Li results. (I will spare you my ugly graph on that for Wets)
The charging profile in the batt-uni link looks the same as for a lead acid battery so it is not all magic. An Li is still a battery.
