VE.Smart Networking

The battery voltage data is used to compensate for voltage-drop over the battery cables. This ensures that the battery is charged with the exact voltage as configured in the charger - instead of a lower voltage due to resistance in the wiring.

The battery temperature data is used to adjust the charge voltages. When cold, a lead/acid battery typically needs a higher charge-voltage …and a lower charge-voltage when it's hot.

For lithium batteries the charge-voltages remain the same at all temperatures, as long as it’s not too cold. Its better to not charge Ltihium batteries below 5C, to prevent them from being damaged and degraded.

The battery current data is used to allow the tail current setting (see the Solar Charger manual for more details) to be used more precisely as, by having the actual battery current, the Solar Charger can decide better if absorption phase should stop and go to equalisation/float phase.

In VictronConnect, the usage of the battery current data is only shown when the Solar Charger is actually charging. When Synchronized charging is enabled, the Solar Charger also needs to be the master. When the Solar Charger is connected to a Venus device that sends the battery current, the value from the Venus device is used, so the battery current will not show up in the VE.Smart networking menu (see also chapter 5: Limitations).
