The REDARC BCDC Alpha50 Battery Charger (BCDC12050B) is a rugged, Australian-designed 12V 50A DC-to-DC charger built to keep your secondary battery fully charged on every adventure. Drawing power from your vehicle's alternator or a solar array of up to 750W, it features REDARC's exclusive Green Power Priority™ technology, which automatically prioritises solar input to minimise load on the alternator and save fuel — a genuine advantage for long-range touring across Australia. With IP67/69K dust and moisture protection and an operating range of -40°C to 85°C, it's engineered to handle the harshest outback, coastal, and high-country conditions without missing a beat.

The BCDC Alpha50 is the go-to dual battery charger for serious caravanners, 4WD tourers, and motorhome owners who demand reliable power at every campsite. It's the only DC-DC charger that can both charge and recover your start battery — in as little as 15 minutes at the push of a button — so you'll never be left stranded on a remote track or a free-camp far from civilisation. Compatible with AGM, Gel, Calcium, Standard Lead Acid, and Lithium (LiFePO4 including heated) batteries up to 300Ah, the Alpha50 fits seamlessly into new and existing 12V setups in caravans, camper trailers, RVs, and 4WD vehicles. Real-time monitoring via Bluetooth and the RedVision app, combined with over-the-air firmware updates, ensures your power management stays current for years to come.
