The REDARC BCDC1250D In-vehicle Battery Charger is a powerful 12V 50A DC to DC charger, representing the latest evolution of the award-winning BCDC Dual series, and incorporating REDARC's innovative Smart Start technology.

Distinguished by a striking red line along its profile, this dual battery charger stands out as the most robust in REDARC's BCDC lineup, boasting a formidable 50-amp charging output. Specifically designed for higher current demands, it introduces an additional charging stage called SoftStart, engineered to handle even the most demanding applications.

Equipped with a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1250D is adept at harnessing power from both solar panels and the vehicle's alternator simultaneously. Moreover, its built-in 'Green Power Priority' ensures that it prioritizes solar charging, alleviating the load on the alternator.

This versatile unit seamlessly adapts to both 12 and 24-volt vehicle systems and functions flawlessly with both standard and variable/smart alternators. Its compatibility extends to a wide range of battery types commonly used in automotive and recreational vehicles, including AGM, Gel, standard lead-acid, Calcium, and LiFePO4 batteries.

As a general guideline, the BCDC1250D is best suited for battery banks exceeding 200AH. For smaller battery sizes ranging from 75 to 200AH, REDARC recommends considering the BCDC1225D.

Proven and Tested

 The BCDC's award-winning technology has undergone rigorous independent verification and testing to guarantee optimal battery life, consistently charging your battery to a verified 100%.* Please note, larger battery banks with substantial capacity may necessitate several charging cycles for full replenishment.

Manufactured in Australia and meticulously tested to withstand our unique environmental conditions, this DC to DC battery charger is ready for the most extreme challenges. It can operate flawlessly in scorching temperatures of up to 80°C and tackle demanding deep water crossings, as seen at Cape York. Be it water, dust, or vibration, this charger remains impervious to these elements.

When venturing into the rugged bush and prioritizing a safe return, you can have full confidence in REDARC's reliability and durability.
