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:
