Functions of Cerbo GX vs VE.Bus BMS?

Do I need the VE.Bus BMS if I get the new Cerbo GX?

The new Cerbo GX will “closely follow managed (lithium) batteries ”. It seems like it could connect to my Victron lifepo’s via Bluetooth, and monitor the batteries.

What functions does the VE.Bus BMS provide that the Cerbo GX lacks?

The Cerbo GX is by no means a BMS and as result does not provide Load disconnect in case of low cell voltage or Charge disconnect in the event of high cell voltage.
The Cerbo will "monitor" your (lithium) batteries, provided there are devices (ie a BMV) installed that provide information such as battery voltage and/or current.
You might want to read the Cerbo manual here to see what's possible and what not.

So if you have Lithium batteries, they need a BMS such as the VE.Bus BMS.
