The REDARC BCDC Alpha25 (BCDC12025B) is a 25A dual-input in-vehicle battery charger built for serious Australian adventurers who demand reliable, intelligent power management on every trip. Pulling up to 25A from your alternator or harvesting up to 500W from a solar array — or both simultaneously — the Alpha25 keeps your auxiliary battery fully charged whether you're driving outback tracks or camped off-grid. Its IP67 and IP69K dual rating delivers genuine dust and high-pressure water protection, so it's equally at home under the bonnet of a 4WD or mounted in a caravan battery bay. An adjustable input current limit means you can dial back alternator draw to protect modern variable-voltage and Euro 6 alternators, preserving your vehicle's electrical health across long hauls.

Designed specifically for the demands of Australian caravan, RV, motorhome, and 4WD touring, the BCDC Alpha25 charges every common battery chemistry — AGM, gel, calcium, standard lead-acid, and lithium LiFePO4 (including heated lithium at sub-zero temperatures). The built-in Bluetooth module pairs with REDARC's RedVision app so you can monitor charging status, adjust settings, and push over-the-air firmware updates without touching the unit. A push-button start-battery recovery mode rescues a flat cranking battery using stored auxiliary power, a genuine lifesaver on remote tracks. Future-proof, versatile, and engineered in Australia, the Alpha25 is the dual battery charger that grows with your setup.
