The REDARC BCDC1250D In-vehicle Battery Charger is a 12V 50A In-vehicle DC to DC battery charger. It is the latest variant of the award-winning BCDC Dual range and features REDARC's Smart Start technology.

Styled with a red line running down its back tells you there's something different about this dual battery charger. A 50-amp charging output makes it the most powerful in REDARC's BCDC range.

The BCDC1250D has been developed to provide a higher current output, it features an additional charging stage known as SoftStart which has been engineered to handle more demanding applications.

Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1250D will charge from both solar and the alternator simultaneously. And, with built-in 'Green Power Priority' it will select solar charging first, meaning less load on the alternator.

Suitable for 12 or 24-volt vehicle systems, the unit will also work with either standard or variable/smart alternators.

It is compatible with all common types of batteries used in automotive and recreational vehicles such as AGM, Gel, standard lead acid, Calcium and LiFeP04.

As a guide, the BCDC1250D is used for battery bank sizes over 200AH. For smaller batteries of 75-200AH REDARC recommends the BCDC1225D.

Proven and Tested

The award-winning technology in the BCDC has been independently verified and tested to ensure battery life is maximised, charging your battery to a proven 100%.

Built in Australia and tested for our unique conditions, the DC to DC battery charger will work in the extreme heat of the Simpson Desert, up to 80°C and can handle deep water crossings at Cape York - water, dust and vibration are no match for this charger.
