The Redarc BCDC Alpha50 R is a 12V 50A DC-DC battery charger and manager for caravans, camper trailers, and 4WDs. It charges from DC (alternator) and solar simultaneously, features built-in Green Power Priority that prioritises solar to minimise alternator load, and includes a Smart Battery Monitor. Pushbutton interface and screw connections for easy installation. Remote monitoring and control via the RedVision Bluetooth app. 164mm x 146mm x 44mm, 0.96kg. Not suitable for engine bay installation. 2-year warranty.

Product overview

The BCDC Alpha50 R functions as a true battery manager rather than a standard DC charger. It adjusts its charge mode in real time to match the battery's needs, extending battery lifespan and maximising charging efficiency. Green Power Priority minimises alternator load by prioritising solar input first, reducing fuel consumption. When paired with the included Smart Battery Monitor, the BCDC Alpha50 R can distinguish between current delivered to the battery and current consumed by system loads. If the charge current is set below maximum, the charger directs unused current to supply system loads directly, reducing reliance on the battery. The BCDC Alpha50 R can also recover a flat start battery in as little as 15 minutes with a pushbutton press or via the smartphone app. Excess solar capacity automatically tops up the start battery once the secondary battery is full. Pushbutton interface and screw terminal connections simplify installation. Over-the-air updates keep the charger's firmware current. Compatible with the TVMS Rogue and TVMS Prime for full RedVision integration.

Features and benefits

50A charging from DC and solar simultaneously.

Green Power Priority: Prioritises solar input over alternator charging to minimise alternator load and reduce fuel consumption.

Smart Battery Monitor included: Distinguishes between charge current to the battery and current supplied directly to system loads.

Direct load supply from unused charge current: When charge current is set below maximum, unused current supplies system loads directly, reducing battery demand and extending battery lifespan.

Charges all common automotive battery types: Including standard and heated lithium (LiFePO4), AGM, gel, calcium, and flooded.

Flat start battery recovery: Recovers a flat start battery in as little as 15 minutes via pushbutton or smartphone app.

Solar to start battery top-up: Excess solar automatically charges the start battery once the secondary battery is full.

Pushbutton interface and screw terminal connections: No soldering or complex wiring required.

Remote monitoring and control via RedVision Bluetooth app: State of charge percentage, time remaining, and charger performance on your mobile device.

Limits input current: Protects vehicle alternators, making it suitable for hybrid and electric vehicles with low surplus current or small DC converters.

Over-the-air updates: Firmware kept current without returning the unit.

Compatible with TVMS Rogue and TVMS Prime for full RedVision system integration.

Not suitable for engine bay installation.

2-year warranty.

Frequently asked questions

What is the difference between the BCDC Alpha50 R and the BCDC Alpha100 R? The BCDC Alpha50 R delivers 50A of charge current and measures 164mm x 146mm x 44mm at 0.96kg. The BCDC Alpha100 R delivers 100A and measures 385mm x 146mm x 50mm at 2.2kg. Both share the same Green Power Priority, Smart Battery Monitor, RedVision Bluetooth connectivity, and over-the-air update capability.

What is Green Power Priority on the BCDC Alpha50 R? Green Power Priority prioritises solar input over alternator charging. When solar power is available, the charger draws from solar first to minimise alternator load and reduce fuel consumption.

Can the BCDC Alpha50 R charge lithium batteries? Yes. The BCDC Alpha50 R charges all common automotive battery types including standard and heated lithium (LiFePO4), as well as AGM, gel, calcium, and flooded batteries.

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

Can the BCDC Alpha50 R be installed in the engine bay? No. The BCDC Alpha50 R is not suitable for engine bay installation.
