Product overview

The BCDC Alpha50 delivers 50A of DC-to-DC and solar charging with Green Power Priority, prioritising solar input over alternator charging to reduce fuel consumption and alternator load. Flat start battery recovery takes as little as 15 minutes via pushbutton, and excess solar automatically tops up the start battery once the secondary battery is full. Configurable input current limits protect the vehicle's alternator. IP67/69K dust and moisture protection and a -40°C to 85°C operating temperature range make the BCDC Alpha50 suitable for engine bay installation and harsh environments. Screw terminal connections and pushbutton interface simplify installation. The RedVision Bluetooth app provides real-time charge status and remote control from a smartphone. Over-the-air updates keep firmware current. Australian designed, tested, and manufactured.

Frequently asked questions

What is the difference between the BCDC Alpha50 and the BCDC Alpha50 R? The BCDC Alpha50 carries IP67/69K protection, is engine bay suitable, and has an operating range of -40°C to 85°C. The BCDC Alpha50 R is not engine bay suitable, has an operating range of -20°C to 60°C, and includes a Smart Battery Monitor for distinguishing charge current from load current. Both deliver 50A and share Green Power Priority and RedVision Bluetooth connectivity.

Is the BCDC Alpha50 suitable for engine bay installation? Yes. The BCDC Alpha50 is suitable for engine bay installation, supported by its IP67/69K protection rating and -40°C to 85°C operating temperature range.

Can the BCDC Alpha50 charge lithium batteries? Yes. The BCDC Alpha50 is compatible with standard lithium (LiFePO4) and heated lithium, as well as AGM, gel, calcium, and standard lead acid batteries.

Is the BCDC Alpha50 suitable for hybrid or electric vehicles? Yes. The adjustable input current limit protects vehicle alternators with low surplus current, making the BCDC Alpha50 suitable for hybrid and electric vehicles as well as vehicles with small DC converters.

What does IP67/69K mean on the BCDC Alpha50? IP67 means the unit is fully dust-tight and protected against temporary submersion in water up to 1 metre. IP69K adds protection against high-pressure, high-temperature water jets. Together they make the BCDC Alpha50 suitable for harsh and wet installation environments including the engine bay.
