Features to know about

High-Amperage Power

When you're miles from camp and running everything from fridges to inverters, 100 amps of charging means you don't have to shut down early. And you can forget slow charging and constant "Are we topped up yet?" checks as you watch the battery meter like a hawk. The BCDC Alpha 100 R packs 100 amps of charging muscle into a single, all-in-one unit, which is twice the output of the 50A model. This charger is engineered for builds with bigger battery banks or for anyone who doesn't have time to wait for a full charge. It's ideal for powering your RV, overlanding rig, or work vehicle.

Smarter Charging, Wherever You Roam

You can stop second-guessing if your gear will stay powered through the night or on your journey. This charger pulls power from your alternator, solar, or battery, and automatically picks the best input to keep your batteries topped off while you're on the move or at camp. Even when you're hunkered down during a surprise storm or off-grid for days, you can count on a steady charge from Redarc.

Control at Your Fingertips

Pair the Alpha 100 R with Redarcs RedVision system or app for live battery info, system diagnostics, and over-the-air updates. Check charge status, manage recovery mode, or control your setup remotely, all from your touchscreen or phone.

Built to Take a Beating

Made in Austrailia, Redarc is known for rugged reliability, and the BCDC Alpha 100 R is no exception. It's vibration tested, water-resistant, and made to survive dusty trails, bumpy roads, and wild weather. Install it, forget about it, and focus on your trip.

No More Dead Batteries

Have you ever come back to your truck after a long hike, turn the key, and.nothing? With the Alpha 100 R, your backup plan is built in. The built-in recovery feature lets you use your fully charged auxiliary battery to bring your starter back to life. All you have to do is open your app, press a button, and you'll be back on the road within 15 minutes.
