The Redarc BCDC ALPHA25 12V 25A DC-DC Battery Charger is an advanced and rugged charging solution, ideal for both off-grid explorers and daily drivers who need reliable power for their auxiliary battery. Built with innovative features, this charger not only powers your adventures but also safeguards your battery’s health, making it perfect for extended travel, camping, and utility setups.

Key Features and Benefits of the Redarc BCDC12025B

• Dual Input Charging: The Redarc BCDC12025B supports both vehicle alternator and solar panel inputs, allowing it to utilise solar power whenever available. This dual input capability prioritises solar energy to reduce strain on your vehicle’s alternator, extending alternator life and optimising fuel efficiency.
   
• Smart Alternator Compatibility: This charger is compatible with modern smart alternators, which can vary their output voltage based on driving conditions. With built-in technology to adapt to these voltage fluctuations, the BCDC12025B ensures consistent charging, even with the advanced alternator setups found in newer vehicles.
   
• Efficient Solar Charging with MPPT and Start Battery Top-Up:
  The Redarc BCDC12025B includes an advanced Maximum Power Point Tracking (MPPT) regulator, which optimises solar charging by constantly adjusting the voltage to maximise power output. When your auxiliary battery is fully charged, the BCDC12025B goes a step further by diverting excess solar power to the start battery, keeping it topped up and ready to go. This feature helps reduce strain on your alternator, saves fuel, and ensures that both your auxiliary and start batteries stay charged, giving you reliable power for extended off-grid adventures.
   
• Start Battery Recovery for Peace of Mind:
  The Redarc BCDC12025B offers a unique Start Battery Recovery feature, providing an essential backup in case your start battery goes flat. With the press of a button or through the RedVision app, the charger can use the auxiliary battery to deliver a quick charge to the start battery, bringing it to a sufficient level to safely restart your vehicle. This process is more controlled than a traditional jump start, helping to protect both batteries from potential damage. The Start Battery Recovery feature provides additional security, ensuring that you won’t be left stranded, even in remote locations.
   
• Wide Battery Compatibility:
  The BCDC12025B supports multiple battery types, including AGM, Gel, Standard Lead Acid, Calcium, and Lithium (LiFePO4). This flexibility means users can confidently charge different battery types, with each receiving a tailored charging profile. The versatility of the BCDC12025B makes it ideal for a range of applications, whether you're charging a standard lead-acid battery for daily use or a high-performance lithium battery for extended trips.
   
• Durable and Rugged Design:
  Built to withstand harsh conditions, the BCDC12025B has an IP67 rating, ensuring protection against dust, moisture, and extreme temperatures. This makes it reliable for rugged outdoor environments and engine bay installations. Whether you’re navigating off-road trails or facing tough weather conditions, the BCDC12025B’s design ensures that your power system remains dependable and consistent.
   
• Intelligent Charging Profiles for Battery Longevity:
  The BCDC12025B intelligently manages charging stages—Boost, Absorption, and Float—designed to maximise battery health. In the Boost stage, it quickly charges the battery; in Absorption, it holds a steady voltage to ensure the battery reaches full capacity; and in Float, it maintains a minimal charge to counteract natural discharge. This automated charging process helps extend battery life by preventing overcharging and maintaining optimal battery health over time.
   
• Built-In Safety Features:
  Safety is a core aspect of the BCDC12025B. Redarc has equipped the charger with multiple protective features, including overcharge, over-temperature, and reverse polarity protection. These safeguards prevent damage to the charger and battery, providing peace of mind whether you’re on the road or parked at a campsite.
   
• Compact and Lightweight Design:
  Despite its powerful performance, the BCDC12025B maintains a compact size, measuring only 164mm in length, 146mm in width, and 44mm in height, with a weight of just 925g. This design makes it easy to fit into tight spaces within your vehicle, adding to its versatility and suitability for a wide range of setups.
   
• Easy Monitoring with Bluetooth Connectivity:
  With Bluetooth compatibility, the BCDC12025B can be monitored using the RedVision Configurator App. The app allows users to check the charge status, battery temperature, and system performance in real-time, providing instant insight into your power system. This feature simplifies power management and ensures you’re always aware of your battery’s condition, even from a distance.
   
• Optimised for Hybrid Vehicles:
  The BCDC12025B includes configurable input current limits, which allow users to adjust the charger’s draw from the alternator. This feature is particularly useful for hybrid vehicles, as it aligns with the unique power requirements of these systems, making the BCDC12025B an excellent option for modern, fuel-efficient vehicles.
