Meet the ProMariner ProSport HD 20 Gen4, a rugged 12/24V, two-bank battery charger designed for boats, RVs, and demanding battery banks. With Gen4 microprocessor control, it charges quickly, protects batteries, and thrives in harsh environments.
-
Output and Banks: 20A total output across 2 independent banks for 12V/24V systems with 120V AC input.
-
Gen4 Smart Control: Microprocessor-based control delivers fast, precise charging with advanced battery protection.
-
Smart Power Distribution: 100% of available charging amps are allocated efficiently by dynamically distributing unused amps to any one or multiple batteries as needed.
-
Advanced Cooling: Tri-surface heat sink design (upper, lower, rear) ensures optimal cooling while delivering true rated current in both charge modes.
-
5-Stage Charging: Analyze, charge, condition, auto-maintain, and monthly reconditioning during storage to fully charge and extend battery life.
-
Energy Efficient Operation: Auto-maintain activates only when needed, reducing AC power consumption and keeping batteries ready without waste.
