For chargers that are already connected and synchronised over VE.Can, pairing them in a VE.Smart Network is not necessary. In case they __are__ paired, the pairing will be ignored. | For chargers that are already connected and synchronised over VE.Can, pairing them in a VE.Smart Network is not necessary.

Synchronising the chargers works in a master-slave manner. The chargers will elect a master among them and that master will be the one to dictate the charge algorithm. As the master cannot be determined by the user, it is important to make sure all chargers belonging to the same network have the **same battery settings**.
