The REDARC BCDC1225D is an advanced dual-input, in-vehicle DC-DC battery charger that delivers professional-grade power management for auxiliary battery systems in 4x4s, RVs, camper vans, trailers, and marine applications. This 25-amp continuous output charger is designed to charge secondary battery banks to 100% state of charge while on the move, utilizing power from both your vehicle's alternator and solar panels simultaneously.
Dual Input Charging Technology:
- MPPT Solar Regulator: Built-in Maximum Power Point Tracking extracts maximum efficiency from solar panels, whether roof-mounted or portable
- Green Power Priority: Automatically prioritizes solar input when available, reducing load on your vehicle's alternator and electrical system
- Simultaneous Charging: Accepts DC power from vehicle (9-32V range) and solar input at the same time for faster, more efficient charging
- 375W Output Power: Delivers consistent 25A charging current to quickly replenish battery banks
Universal Battery Compatibility:
Features selectable multi-stage charging profiles optimized for AGM, Gel, Standard Lead Acid, Calcium Content, and LiFePO4 (Lithium) batteries. The microprocessor-controlled charging algorithm ensures each battery type receives the precise voltage and current profile for optimal performance and longevity. Suitable for battery bank sizes of 75-200Ah in most applications.
Built for Extreme Conditions:
- Fully sealed, potted electronics resist water, dust, and vibration
- Operating temperature range: -10°C to 80°C (14°F to 176°F)
- Proven in deep water crossings and harsh off-road environments
- Fan-free cooling design eliminates moving parts for enhanced reliability
- IP-rated protection against environmental infiltration
Smart Vehicle Integration:
Compatible with both 12V and 24V vehicle electrical systems. Works seamlessly with standard alternators and modern variable-voltage/smart alternators found in newer vehicles. The wide 9-32V input voltage range compensates for voltage drop over long cable runs, ensuring optimal charging even in large vehicles or trailers.
