Dual Pro SS3HF Sportsman Series Hi-Frequency 3-Bank 30A Marine Battery Charger

The Dual Pro SS3HF Sportsman Series High Frequency is a fully automatic, 3-bank on-board battery charger delivering 30 amps total — 10 amps per bank — with true independent outputs that maintain full power to each bank simultaneously. Building on Dual Pro's decades-long legacy in marine charging, the SS3HF brings the Sportsman Series into its next generation with a significantly lighter and more compact form factor compared to the original transformer-based SS3.
