REDARC BCDC1250D: The Ultimate Aussie 4WD DC-DC Battery Charger
Designed for tough Aussie conditions, the REDARC BCDC1250D is a 12V, 50A In-vehicle DC-DC battery charger that keeps your auxiliary battery fully charged—whether you're driving or parked up using portable solar panels.
This latest version of REDARC’s award-winning BCDC Dual range features Smart Start technology and delivers the highest charging output in the range. It’s built to handle high-demand setups, making it perfect for 4WDers running fridges, lights, winches, and other power-hungry accessories off-grid.
Equipped with Maximum Power Point Tracking (MPPT) solar regulation, it charges from both solar and your alternator simultaneously. Thanks to Green Power Priority™, it automatically selects solar first reducing strain on your alternator and saving fuel.
Designed to work with 12V and 24V vehicle systems, the BCDC1250D is compatible with both standard and variable/smart alternators. It suits AGM, Gel, Lead Acid, Calcium, and LiFePO4 batteries, making it an essential addition for serious touring, overlanding, and remote travel.
For battery banks over 200Ah, the BCDC1250D is the go-to choice. If you’re running 75-200Ah, REDARC recommends the BCDC1225D instead.
