Product Description

Smart 12V/24V DC-DC Charging for Dual-Battery Systems

The Victron Orion-Tr Smart 12/24-15 DC-DC Charger is a professional-grade 15 amp (360W) charger designed for modern dual-battery systems in vans, RVs, overland rigs, and boats. It takes unstable alternator output and converts it into a programmable three-stage 24V charger—helping protect your 12V charging system while properly charging your 24V house or service battery bank.

With fully programmable charging profiles, built-in Bluetooth connectivity, and support for both lead-acid and lithium batteries, this compact charger gives you precise control over how your system charges. It is an ideal choice when you want reliable, efficient charging that matches the quality of the rest of your electrical system.

Important: This non-isolated model is for applications that have a common ground like vehicles and RV's that use the chassis as a shared ground for both battery systems. For applications where the grounds are not shared (more common in marine setups), an Isolated DC-DC Charger will be needed.

Key Features & Benefits

Adaptive 3-Stage Charging – Uses bulk, absorption, and float stages to optimize charging based on battery state of charge, helping extend overall battery life.

Lead-Acid and Lithium Compatible – Supports common AGM, gel, flooded, and LiFePO4 batteries, making it a flexible choice for upgrades and mixed fleets.
Parallel-Ready Design – Multiple units can be wired in parallel when your system requires more than 15A of DC-DC charging capacity.
Rugged, Compact Construction – A small housing with screw terminals make it easy to integrate into tight spaces in vehicles and marine installations.
