REDARC BCDC Alpha25 12V 25A DC Battery Charger

Charge smarter. Go further.

The REDARC BCDC Alpha25 is a rugged, compact DC-DC battery charger built for life on the road. Designed to keep your start and secondary batteries topped up from both your vehicle’s alternator and solar, it delivers efficient 25A charging—whether you’re parked up in the bush or cruising the highway.

Thanks to REDARC’s Green Power Priority, the Alpha25 automatically favours solar input when available, saving fuel and reducing strain on your alternator. Plus, with Bluetooth connectivity, you can monitor charge status in real time using the RedVision smartphone app.

Flat start battery? No worries. A built-in pushbutton recovery function lets you jump your start battery in minutes. And when your secondary battery is full, the Alpha25 puts that leftover solar power to work by topping up the starter too.

Made for the engine bay, the Alpha25 is sealed tough with IP67/69K protection, giving you reliable performance in dust, water, and heat. Installation is simple with pushbutton setup, screw terminals, and no complex wiring. Pair it with REDARC wiring kits and brackets for a fast, tidy fit.
