Wrong Batterie Temp indication

My Multiplus II 3000 has a temperature sensor with cable for the battery.

I connected the eye at the plus pole of the battery.

And made sure the connection at the Multiplus has the right direction +/-.

In the VRM it shows -9°C. The Temp in the room ist +17C.

Faulty Sensor, faulty Multiplus or wrong connected?

Or a bug?

This one goes on the negative pole, not the positive.

I finish now with that issue.

Tried diffrend poles at the battery. Changed the cables at the Victron. No help.

VRM Portal shows minimum -8° Celsius. Tempeartere is about 18 plus.


I managed now to setup a DIYBMS via CAN bus on the GX.

This works and shows reliable Battery temperatures now.
