Renogy 12V 20A DC to DC Battery Charger

Renogy 12V 20A DC-DC Battery Charger allows you to charge your 12V auxiliary battery from the starter battery in your RV. The supported auxiliary battery types include deep-cycle gel-sealed lead acid batteries (GEL), flooded lead-acid batteries (FLD), sealed lead-acid batteries (SLD/AGM) or lithium iron phosphate batteries (LI). In addition, the battery charger provides a user-defined battery mode that allows for more battery setting flexibility. 

This second-generation charger delivers an unparalleled driving charge experience, enhanced by smart control technology. Compatible with both smart and traditional generators, it maximizes energy efficiency while protecting your vehicle’s batteries. With advanced electronic protections and up to 94% charging efficiency, this charger ensures reliable performance on the road. The intelligent charging logic optimizes the charging process, and with remote monitoring via the DC Home app (free of charge) or Renogy ONE Core (sold separately), you can effortlessly monitor your battery system’s status. 

Key Features:

• Advanced High-Temperature Performance. Effortlessly converts between 12V systems with over 90% efficiency for boosting and 94% for voltage reduction, offering a dual charging solution adaptable to various DIY configurations.
• Alternator Running Detection . Features an advanced alternator running detection system, which effectively monitors the alternator’s status to prevent overdischarge of the starter battery. This ensures that the starter battery remains adequately charged and ready for vehicle ignition.
• Optimized Battery Health. Enables or disables lithium battery activation based on battery status via the DC Home app, extending battery lifespan.
• Extremely Compact and Lightweight. Compact and light enough to be mounted in engine compartment and side storeroom, allowing for a more spacious and comfortable living space.
• Smart Control for Simplicity and Efficiency. The included BT-2 Bluetooth module allows for seamless remote monitoring of the battery charger through the DC Home app on your smartphone, providing real-time insights into the charging process and enabling you to track performance over time and make informed decisions for optimal battery management.
