Do you have a start battery and an extra leisure/auxiliary?


Victron Energy Orion-Tr Smart 12/12-Volt 30 amp 360-Watt DC-DC Charger, Isolated (Bluetooth)


This charger will solve the problem with a start battery and a leisure/auxiliary battery, no battery switch is needed and the start battery is not envolved with the leisure battery.


If you are investing in a lithium battery in your RV or boat then this is a must, the alternator can break due to the high amp the lithium battery can charge.

The charger starts when it knows the engine and alternator is running and start to charge the other battery or you can trigger it with switch manually.

  • For use in dual battery systems in vehicles or on boats where the (smart) alternator and the start battery are used to charge the service battery.


The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch and has an engine running detection mechanism.


  • The Orion Tr-Smart charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries.
