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...

Well, I find it all very confusing, so it is a good thing I don't have an Li-ion battery.
Your post showed amps tapering from about 85%. That would normally indicate you are in the absorption stage. Yet we are being told that does not happen so soon with Li batts. Where does that 20-30 minutes come in?
With Wets and AGMs it happens that the higher the charging rate (amps wrt to battery AH), the lower the SOC when Vabs is reached and Absorption begins with its tapering amps. It should be the same with Li batts, but perhaps with a higher set of SOCs.
The charging profile graph in the batt uni link should have helped but does it?
BB seems to want you to limit the charging rate to about a 50% charging rate. Typical wet 6s can do about 33% without difficulty. Ordinary AGMs spec limit is about 27-30% but Lifeline AGM allows huge amps in Bulk. If you do the huge amps, expect a low SOC for when amps start to taper.
The BB replies to questions in their link seem somewhat inconsistent or contradictory wrt "floating" at 13.6 and when is "full".
It would be more use if more people with knowledge of all this would post their experiences in managing their Li batts. I find it all bewildering, but I don't have to actually figure it out except from curiosity.
With what those things cost, I would want to know exactly how to manage them if I got any!
