Always Ready, Wherever You Go
Stay powered up on every journey with the REDARC BCDC Alpha25 DC-DC charger. Delivering 25 amps of efficient charging, it draws energy from your vehicle’s alternator or solar panels to keep both your start and auxiliary batteries fully charged. Its built-in Green Power Priority™ system automatically favours solar input, reducing alternator strain and helping improve fuel efficiency.

Real-Time Power Monitoring
Take full control of your system through Bluetooth and the RedVision mobile app. With live status updates and adjustable input current limits, you can customise performance to suit your setup and safeguard your vehicle’s electrical components.

Start Battery Recovery Made Easy
With the push of a button, you can bring a flat start battery back to life in as little as 15 minutes—getting you back on the road fast. And when your auxiliary battery is topped up, any leftover solar power is intelligently redirected to recharge your start battery.

Quick and Hassle-Free Install
Designed for convenience, the BCDC Alpha features a user-friendly push-button interface and screw-type terminals for straightforward wiring—no soldering required. Pair it with available mounting brackets and wiring kits to streamline the installation process even further.
