Just for anyone searching for the settings for Ve Configure with a Lifepo4 Battery (16S) of 52 volt here are the VE.Configure Settings which work fine and I think (together with AI) these are the most optimal I think.
TAB: General
State of charge when Bulk finished 99.0 %

TAB: Inverter
PowerAssist unchecked
Inverter output voltage 230 V
Inverter DC shut-down voltage 46.40 V
Inverter DC restart voltage 48.00 V
Low DC alarm level 47.60 V
Do not restart after short-circuit (VDE 2510-2 safety) unchecked
enable AES unchecked
TAB: Charger
Enable charger checked
Weak AC input unchecked
Stop after excessive bulk unchecked
Lithium batteries checked
Disable VSense (for diagnostic purposes) unchecked
Configured for VE.Bus BMS unchecked

Float voltage 54.40 V
Charge current 70 A
Repeated absorption time 1.00 Hr
Repeated absorption interval 14.00 Days
Absorption time 1 Hr
TAB: Virtual switch
TAB: Usage
Virtual switch usage Do not use VS
TAB: Assistants
TAB: Assistant Configuration
ESS (Energy Storage System) (size:1815)
*) System uses LiFePo4 with other type BMS
(This can be either a BMS connected via CAN bus (e.g. a Lynx Smart BMS) or a
BMS system in which the batteries are protected from high/low cell voltages by
external equipment.)
*) The battery capacity of the system is 314 Ah.
*) Sustain voltage 50.00 V.
*) Cut off voltage for a discharge current of:
0.005 C= 48.00 V
0.25 C= 47.20 V
0.7 C= 46.40 V
2 C= 46.40 V
*) Inverting is allowed again when voltage rises 1.20 V above cut-off(0).
*) Relevant VEConfigure settings:
- Battery capacity 314 Ah.
- PowerAssist unchecked
- Lithium batteries checked
- Dynamic current limiter unchecked
- Storage mode unchecked
Total size of all assistants including the required
(hidden) system assistants is: 1888
TAB: Advanced
limit internal charger to prioritize other energy sources unchecked
I also found this manual for Dyness batteries which is pretty conservative imo, but needed to guarantee vendor warranty: https://communityarchive.victronenergy.com/storage/attachments/dyness-battery-and-victron-inverter-setup-manual-2.pdf
