Versatile and robust, it's compatible with AGM, flooded, gel, and lithium batteries, featuring automatic voltage adaptation, comprehensive protections against overcharge, reverse polarity, and overheating, plus support for both traditional and smart alternators. A built-in temperature sensor ensures precise charging (sensor sold separately), while the DIP switch allows easy customization for different battery types.

Compact yet powerful, it measures 12.2 x 6.9 x 2.7 inches and weighs just 5.3 lbs (2.4 kg), making installation straightforward in tight spaces. Certified CE and RoHS, the Renogy 60A charger keeps your system reliable on the move—priced at $209.99.
