On my recent upgrade i fitted 2 x Ecoworthy 100amp lithiums along with a Victron smart shunt to monitor them as they have no bluetooth function.
Within the shunt app are some battery settings.. I contacted Ecoworth ref their battery settings and received the following back, posting in case its of use to anyone.
I have not tried these as yet but will do once i have installed a couple of new solar panel.

Absorption voltage: 14.6V
Floating voltage: 14.6V
Balanced voltage: none
RE-BULK voltage offset: None
A absorption duration: fixed (adaptive/fixed)
Maximum absorption time: 120min
Tail current: 5A
Current percentage: 1%
Automatic equilibrium: disable (disable/every ____ heavenly equilibrium once)
Equal stop mode: fixed time (fixed time/automatic voltage)
Maximum equilibrium duration: None
Temperature compensation (MV/° C): None
Low temperature cut off (optional): Discharge -20 ℃ charge 0 ℃

That float voltage looks really high Steve would expect it to be 13.4v to 13.6v
 
Agree with Dave’s post above Steve. The thing with lithium is that you don’t need to hammer in every amp at the end when charging.. best possible way to use is charge to around 90/95% max, discharge to around 30% or so max.

Good info Steve.
Any reason why the max absorption time is 120 mins ( 2 hrs) I would have thought the longer the better for cell balancing. Just something I read.

I use 2hr absorption just for balancing if needed as my balancing doesn't start till 13.4v same as my float voltage. If the float voltage was the same as absorption voltage you would have in effect no float only absorption.

Fogstar (I'm just setting one up) suggest 30 minutes per 100Ah of battery at 14.2V.

Agree with others that the Float voltage proposed by Ecoworthy seems far too high 13.6V is recommended by Fogstar which would be equivalent to the max fully charged voltage amount.

Normally 30 min to 1 hour for Lithium, not that important as if using a proper lithium charger the current hardly drops off in absorption mode unlike with lead where it will drop to 2 amps..
If my batteries are charging at 90 amps when the charger goes to absorption mode charge current drops to about 80 amps.
 
Absorption voltage: 14.6V

Far too high best to set the absorption/charge voltage to 14.2/14.3v .
14.6v is the absolute max far better to play safe they will still fully charge it will just take a little bit longer at 14.2v.

Best to set the float voltage to 13.5v as at 13.5v the batteries won't take any charge unless current is being drawn from them.

These are my current settings on the Victron smart shunt.

When I see advise from battery vendors to charge to 14.6v I realise they have no understanding of what they sell, just rely on copy paste. One profile fits all, unfortunately in real life does not work.

Ah but they are “professionals” Raul…😆🤣😂😏
