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...

Those setting are basically for all lfp batteries not just BB. Depends on the voltage needed for balancing cells.
I've been using Bulk 14.1v, 14.2v absorb (10 minutes), float 13.6v for almost 4 years now with everyday use.
You have posted that the Absorption Stage for Li does not start till at a high SOC compared with Wets and AGMs.
The BB advice keeps referring to a full charge, but there is also talk of only operating at 80% and under. So when saying they want a charge rate of half AH capacity (which is a lot) or less, and an Absorption time of 20-30 minutes to get to full, does that compute?
IE will that "extra" half hour at 14.4 once amps start to taper get you to full?
Your 10 minutes would then get you from whatever SOC Bulk ends at (95%?) to part way closer to full, but this is still way over 80%?
It is hard to figure out what the "rules of thumb" really are for
1.when camping and
2. for getting to true full and
3. when you should go to full and not stay in the operating zone of SOCs.

"Here are our (BB's) charging parameters for our batteries:
Bulk/absorb 14.2 – 14.6 Volts(14.4 is great)
float 13.6 Volts or lower
No equalization(or set it to 14.4v), no temperature compensation and absorption time is 20-30 minutes per battery(if its an option)."
