Hi, when you connect to the batteries with VictronConnect App, there is a possibility to set a temperature offset per battery.

I put a thermometer next to the batterys to get the correct temperature and set that offset in the batteries, so that every battery is reporting the correct temperature before I install them.

Best Regards,

Markus

I know that in the latest firmware one can adjust the temperature offset.

How is the battery offset value used by the system?

The battery sends allow to charge and allow to discharge signal to the VE.Bus BMS (via M8 circular connector).

You can set the allow to charge minimum temperature inside the battery.

The temperature offset is influencing the battery temperature measurement and therefore influences the temperature setting of the allow to charge signal to the BMS.

I hope this answers you question.
