REDARC BCDC Alpha50 R 12V 50A DC Battery Charger

12V 50A DC-DC Battery Charger with Smart Monitoring
Not suitable for engine bay installation

Take full control of your dual battery setup with the REDARC BCDC Alpha50 R, a smart 12V, 50A DC-DC charger built for serious touring. Whether you’re running a caravan, canopy setup or off-grid rig, this unit delivers fast, efficient charging from both your vehicle’s alternator and solar input.

Paired with REDARC’s Smart Battery Monitor, it goes a step beyond a standard charger, dynamically directing power where it’s needed. When your batteries don’t require full charge input, the system uses spare current to power your loads directly, easing battery stress and improving lifespan. It’s true battery management, not just charging.

When power is tight, the Alpha50 R helps recover a flat starter battery in as little as 15 minutes. And once your auxiliary battery is full, it’ll automatically send excess solar to top up your starter, helping you avoid flat starts the next morning.

You can track everything in real-time with Bluetooth connectivity and the RedVision app, from charge status and current draw to time remaining. For full system integration, it also works with REDARC’s TVMS Rogue or Prime, creating a fully connected power hub in your setup.

The Alpha50 R is simple to install with a clean pushbutton interface and screw connections—no soldering or guesswork required.
