Dual Pro SS4 40A Four-Bank Sportsman Charger

Four batteries call for a charger that can manage each bank rather than relying on a single shared charging lead. The Dual Pro SS4 Sportsman Series supplies 40 amps total through four 10-amp outputs. It is designed for onboard charging in fresh- and saltwater boating applications. The Sportsman series emphasizes a smaller and lighter format than the heavier Professional Series models.

The charger uses independent automatic multistage charging outputs and provides a battery maintenance mode. Its microprocessor-controlled system includes LED charge indications and diagnostic codes. This model is described for wet-cell and AGM batteries; suitability for other chemistries should not be assumed. Temperature compensation and reverse-polarity protection are among the documented charging features.

Waterproof construction makes the SS4 suitable for a permanent marine mounting location. It comes with five-foot DC charge cables and a three-foot AC power cord. It is also described as ignition protected and meeting ISO 8846 marine requirements. Browse our marine battery charging equipment to compare other bank arrangements.
