Victron 18A 12V DC to 12V DC isolated battery-to-battery charger for lead acid or lithium batteries with Bluetooth connectivity and galvanic isolation
Victron 18A 12V DC to 12V DC isolated battery-to-battery charger for lead acid or lithium batteries with Bluetooth and galvanic isolation
- Compact 18A charger with full galvanic isolation suits smaller dual-battery setups in vans or site equipment.
- Bluetooth monitoring prevents ground loops and noise for electronics-heavy commercial applications.
- Multi-stage charging from starter to service batteries works with smart alternators on short journeys.
This Victron Orion-Tr Smart 18A isolated DC-DC charger transfers power from a 12V starter battery to charge a 12V leisure battery safely. Galvanic isolation (up to 200VDC) eliminates current leakage between batteries, ideal for vehicles with sensitive electronics or marine use. For wiring into existing systems, our UK experts recommend trusted installation partners.
Key Features
- Bluetooth Smart via VictronConnect app for monitoring, programming, and remote on/off control.
- Adaptive 3-stage charging (bulk, absorption, float) for lead-acid or lithium batteries.
- Galvanic isolation between input, output, and case prevents interference and corrosion.
- Engine running detection; full protections against overload, short circuit, and overheating.
- LED indicators; parallel multiple units; compatible with solar chargers.
