Victron Orion Smart 30A 12V DC to 12V DC automatic multi-stage intelligent battery-to-battery charger for lead acid or lithium batteries with Bluetooth connectivity


This intelligent battery charger is designed to automatically?ÿcharge one 12V battery /?ÿbattery bank from another 12V battery / battery?ÿbank?ÿwith its own energy source.?ÿFor example, if one 12V battery / bank is?ÿbeing regularly charged by solar / mains/ alternator, this 30A DC-to-DC battery charger can?ÿpull energy from this battery?ÿbank to charge a second 12V target battery or battery bank. The target battery / bank?ÿwill be charged?ÿat a maximum of 30A, using an intelligent multi-stage approach with full overcharge protection.

This compact and lightweight battery to battery charger can be easily integrated or retrofitted into any 12V system, allowing the user to transform a single battery system into a dual battery charging system. For example, in a vehicle or boat this charger can take energy from the engine starter battery (which is constantly topped up by the alternator) to charge a leisure or auxiliary battery / bank.

In a solar charging system, the charger allows easy conversion from a single battery solar charging kit to a dual battery charging kit, without the need to upgrade the single battery solar charge controller to a dual battery model. This is perfect for systems with a high solar input, where a suitable dual battery solar charge controller is expensive or difficult to procure.

The Orion Smart charger can also operate in a DC conversion mode, where the output power will be adjusted to a stable voltage with minimal electrical noise. This allows the running of sensitive DC equipment from a battery or other DC power source which may change voltage during charging or use.

Key features:

  • Bluetooth connectivity: inbuilt Bluetooth feature allows the charging process to be monitored and settings to be changed at any time using the ?ÿVictronConnect App, without having to access the installation location.

  • Safe unattended charging: the unit features?ÿinbuilt safety functions (protection?ÿagainst overload, overheating, overvoltage, short circuit, and reverse discharge of the battery), which allow the charger?ÿto be?ÿleft permanently connected to the source battery?ÿfor unattended automatic charging.

  • Continued charging during battery/load use: the charger will continue to operate at full power whilst energy is drawn from the battery during use.?ÿThe unit will maintain the charge if the battery is already at full capacity. Any 12V loads?ÿmay also be left permanently connected and running whilst the DC-to-DC charger is in operation,?ÿand will be protected against overvoltage and voltage fluctuations.

  • Compatible with other charging sources:?ÿthanks to the inbuilt suppression filter, the batteries may be charged?ÿfrom?ÿalternative power sources, for example?ÿsolar panels / petrol generators etc., whilst remaining connected to the battery charger.

  • Remote on/off control: using a hard-wired switch, external relay control?ÿor the Victron Connect app, the charger can manually be turned on or off. This allows for greater control over when the charger activates, or automatic control by a Battery Management System.

  • Vehicle battery optimisation: specifically designed with efficient vehicle battery charging in mind. Unlike?ÿother chargers (or split charge relays) which do not instantly charge the battery at full current whilst driving and do not?ÿprovide overcharge protection, this unit will automatically charge at full power, even during short journeys, with full protection?ÿfrom overcharging the target?ÿbattery.?ÿThis charger is also well suited to vehicles of Euro?ÿ6 emission standard and above, as?ÿit?ÿprevents the reduced or intermittent charging associated with smart alternators in these vehicles.

  • System upgrade potential: this unit may be connected in parallel to an identical model in order to boost the charging capacity of the system. This is an ideal option for large battery systems, or those with powerful 12V appliances running directly from the batteries. A second unit may be added at any time for future system expansion.

Additional features:

This charger also features LED indicators to show target battery charging stage and Bluetooth connectivity?ÿstatus.


This DC-to-DC battery charger is suitable for use with any 12V lead acid or lithium batteries. It is not compatible with 24V batteries or a combination of 12V and 24V batteries.
