Victron Energy Orion XS 12/12-50A: 12 V specs and what it works with

The Victron Energy Orion XS 12/12-50A is rated for 50 A of charge output maker spec, about 710 Wh per hour of driving at 14.2 V calculated. That is within the max charge current of 12 of 12 batteries we list. Data updated Oct 18, 2026.

Battery charge-current check

Install and wire it exactly as the maker's manual says; we don't size alternators, cables or fuses. The check compares the charger's rated output with each battery's published max charge current (one battery). See the alternator and DC-DC check.

Notes on the sources

Victron states the 1-50 A range applies to both input and output current settings; the datasheet does not list LiFePO4 voltages (set in VictronConnect).

In the maker's words

“An integrated mechanism detects whether the engine is running (engine shutdown detection), which only activates the charger when the alternator supplies power.” (smart alternator quote; source)
