REDARC BCDC Alpha50 – 50A DC to DC Charger

Maximum power, maximum confidence.
The REDARC BCDC Alpha50 delivers a massive 50A of fast, efficient charging to keep even the largest dual-battery setups powered — no matter how demanding your gear is. Whether you’re running fridges, lights, inverters, comms, or full touring systems, the Alpha50 ensures your start and auxiliary batteries stay topped up using power from your vehicle’s alternator or solar.

With Green Power Priority™, solar is automatically prioritised to reduce alternator load, minimise fuel consumption, and maximise free energy from the sun.


Instant Insight

Stay fully informed with real-time monitoring and control via Bluetooth and the RedVision smartphone app. View charge status instantly, customise input current limits, and protect your electrical system by tailoring performance to match your vehicle and battery setup.


Start Battery Recovery

A flat start battery won’t stop your adventure. The BCDC Alpha50 can recover a flat start battery with a single button press, getting your vehicle ready to start again quickly and safely. Once your auxiliary battery is full, the Alpha50 automatically diverts excess solar power to top up your start battery — so no energy goes to waste.


Simplified Installation

With a pushbutton setup, screw terminals, and no soldering required, the Alpha50 is designed to make installation as easy as possible. Paired with REDARC’s range of wiring kits and mounting brackets, it’s simple to achieve a clean, professional install.


Built Tough for Australia

Designed, tested, and manufactured in Australia, the Alpha50 is engineered for harsh touring conditions. With IP67/69K dust and water protection, it’s built to outlast and outperform, even in extreme heat, corrugations, and wet environments.

Before use on March 15 two days later March 17 engine light still on
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I read the specs on this product and it was guaranteed to cleanse as well as turn engine light off in vehicle. I received it March 14.2026 and used it on March 15.2026 I took a picture on Sunday before I entered it into the gas tank engine light was on at that time. Today is March 17.2026 and engine light is still on. The truck was driven for one hour on the 15th 45 minutes on the 16th and 50 minutes on 17 March. Still the engine light is on. Got home parked the vehicle took a picture again to show engine light is still on product guaranteed it was shut it off, but unfortunately product does not work.

It works!
Size: 1 Count (Pack of 1)
My 2005 Jetta failed the inspection and my mechanic said (after clearing the engine light) that I should drive the car for 20 min highway and 20 local. We've tried that the whole day but out of three lights on his device only 1 went away. Next day the light engine came back. After not being happy with the explanation offered by him (a family friend) that I should keep driving it until we get lucky I went online and found CRC 05063. Followed the instruction (one bottle on full tank of gas). Before my tank was under 3/4, engine light went off!! At half tank I went and did the inspection - IT PASSED! I am really impressed! Update August 2015! I have been using this product for 2-3 years now and if it is not working for you please read. In July I have used the first bottle and took my 2005 Jetta for inspection. It failed. Ordered a second bottle and it failed again. My mechanic said keep driving. Did 200 miles in one day and nothing. Decided to take matters in my own hands and ordered Autel MaxiScan MS300 ($18, it allows you to read and delete codes). There were two faults - EVAP and 2nd something about Oxygen. Went online and this is the first time I heard about driving cycles. These are steps that you have to follow so that your car's computer can start measuring all the parameters needed for the test. Driving cycles are not exact science but I tried to follow the instructions as much as I could and after just 20 minutes (10min city and 10min highway) ALL the parameters were set and I passed the emission test with flying colors! So, just before you give a comment about CRC like "tried and didn't work" be aware that there are other things you have to take into account.

This product never fails (no pun intended), I have been using this for the last 10 years my car has never failed a smog test. I highly recommend this and that you use it correctly. You will not be disappointed.
