REDARC BCDC Alpha25 12V 25A DC to DC Battery Charger

Keep your start and secondary batteries charged no matter where the track takes you. The BCDC Alpha25 delivers 25A of smart DC to DC charging from your vehicle's alternator or solar, with Green Power Priority™ built in to favour solar input first — easing the load on your alternator and saving fuel along the way.

Never Get Stranded With a Flat Start Battery Again

Tired of second-guessing your battery setup or getting caught out with a dead start battery in the middle of nowhere? The BCDC Alpha25 gives you the power and control to keep both batteries topped up and ready to go, wherever your adventure takes you.

Smart Charging, Full Control

This DC to DC charger doesn't just charge — it thinks. Configurable input current limits let you tailor charging to your system and protect your electrical setup, while Bluetooth® connectivity and the RedVision app give you real-time monitoring and control of your charge status, right from your phone.

Recover a Flat Start Battery in Minutes

Flat start battery? No drama. Recover it with the push of a button in as little as 15 minutes, getting you safely back on the road. Excess solar power isn't wasted either — it's automatically directed to top up your start battery once your secondary battery is full.
