Hello,
I am in the process do build a DIY LiFePO4 Battery (16s, 280Ah) which should feed a Multiplus 2 GX. I have seen from various posts that the widely used Daly BMS will cause a lot of trouble in connection with the MP2 or the Cerbo GX. Which BMS can be recommended for use with the MP2GX?
Thank you, Tom
Any BMS claiming a successful communication protocol with Victron environment will work (unfortunately I don't think Daly is one of those), you can go for Seplos, JKBMS or others
But be aware that using such a BMS, not validated by Victron, will cause Victron staff not even responding to any question or problem you may have with their HW
You could start here to see if there should bee a bms you could use.

for my self I use REC bms and it work like a charm. It is a litle hard to configure but I have made a xcell to calculate some off the values.

Thank you for your input, but meanwhile I found a solution which enables to use most BMSs with Victron GX. It's a driver for the Venus OS, made available by Louis Van Der Walt over GitHub: https://github.com/Louisvdw/dbus-serialbattery.
There are some interesting YT videos showing how this works, i.e. https://www.youtube.com/watch?v=sHIlP2oJ3DU
