Cerbo GX monitoring 144V battery?

Hello,

I am currently having a car converted to electric drive, which I would like to use as a motorhome.

The driving battery has 144V and it also supplies the 12V network and supplies 230V via an inverter.The system uses the Boostech BMS V3.

I would like to monitor the camping functionalities with a Cerbo GX: water tank levels, temperature and also the battery.


Question: how can the 144V battery be monitored with Cerbo GX?

The person who does the electric conversion says Victron can only do 48V...

Can a smart shunt measure current on a 144V battery?

Thx,
Reka

The SmartShunt likewise cannot work on 144v; your easiest solution would be to use a BMV-700H or BMV-710H Smart, which are both battery monitors specifically designed to work on very high voltage (up to 385v) and would then connect to the Cerbo using VE.Direct just like the SmartShunt/etc.

There is a high voltage BMV for that:

The Cerbo itself must be powered from 12V.
