Always lots of questions on what to set your BMS to for charging Lithium, the main point to note here is that unlike Lead Acid/AGM type batteries, Lithium do not require a float charge, they simply like to be charged and dis-charged but the general idea if you want them to last is use the mid capacity of the cell, i.e not fully charge it (1 cycle) nor fully dis-charge it, but everyone has a preference on this! My 1200ah x 12v pack has been fitted 18 months now 24/10/22 and cycled 38 times! That is with daily usage!
But here’s a good video to get you started if your a bit perplexed by it all.
