The REDARC BCDC1250D Classic DC to DC Battery Charger delivers a robust 50A output at 750W, engineered to maximise the performance and lifespan of your auxiliary battery on the road. Featuring REDARC's signature Green Power Priority technology, the BCDC1250D intelligently charges from solar first — reducing alternator load and drawing on vehicle power only when solar input is insufficient. With a wide input voltage range of 9–32V, it's fully compatible with modern 12V and 24V vehicles running standard, variable-voltage, and smart alternators, making it one of the most versatile DC-DC chargers available for Australian touring setups.

Purpose-built for Australian caravan, camping, and 4WD adventures, the BCDC1250D handles the demands of extended off-road travel and remote touring where reliable auxiliary power is non-negotiable. Whether you're running a dual-battery system in a 4WD, powering the fridge and lighting in a caravan or camper trailer, or keeping a lithium house battery topped up in a motorhome or RV, this charger delivers consistent, four-stage charging across all common battery chemistries — AGM, GEL, lead acid, calcium, and LiFePO4. Its compact 165 × 120 × 37 mm profile and under-bonnet installation rating make it ideal for tight vehicle fitments across a wide range of rigs.
