Product overview

The BCDC Alpha25 delivers 25A of DC-to-DC and solar charging with Green Power Priority, prioritising solar input over alternator charging to reduce fuel consumption and alternator load. The pushbutton interface allows flat start battery recovery in as little as 15 minutes, and excess solar automatically tops up the start battery once the secondary battery is full. Configurable input current limits give full control over alternator protection. IP67/69K dust and moisture protection makes the BCDC Alpha25 the most robust option in the Alpha range, with engine bay suitability and an operating temperature range of -40°C to 85°C for demanding installation environments. Screw terminal connections and pushbutton interface simplify installation. The RedVision Bluetooth app provides real-time charge status, state of charge, and remote control from a smartphone. Compatible with the TVMS Rogue and TVMS Prime for full RedVision integration. Australian designed, tested, and manufactured.

Frequently asked questions

What is the difference between the BCDC Alpha25 and the BCDC Alpha50 R? The BCDC Alpha25 delivers 25A, carries IP67/69K protection, is engine bay suitable, and has an operating range of -40°C to 85°C. The BCDC Alpha50 R delivers 50A, includes a Smart Battery Monitor, is not engine bay suitable, and has an operating range of -20°C to 60°C. Both share Green Power Priority, RedVision Bluetooth connectivity, and over-the-air updates.

Is the BCDC Alpha25 suitable for engine bay installation? Yes. The BCDC Alpha25 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 Alpha25 charge lithium batteries? Yes. The BCDC Alpha25 is compatible with standard lithium (LiFePO4) and heated lithium, as well as AGM, gel, calcium, and standard lead acid batteries.

Is the BCDC Alpha25 suitable for hybrid or electric vehicles? Yes. The adjustable input current limit protects vehicle alternators with low surplus current, making the BCDC Alpha25 suitable for hybrid and electric vehicles as well as vehicles with small DC converters.

What does IP67/69K mean on the BCDC Alpha25? 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 Alpha25 suitable for harsh and wet installation environments including the engine bay.
