Dual Pro Battery Chargers

Why Dual Pro Stands Apart in Battery Charging

Dual Pro, the flagship charger brand of PRO Charging Systems, has been setting the standard in battery chargers since 1989. Engineered and assembled in Nashville, Tennessee, Dual Pro chargers are widely recognized across the boating, recreational, and industrial worlds for their durability, intelligent charging technology, and long service life. Today, the brand is trusted by over 50 boat manufacturers and is the preferred charger of professional anglers competing on the B.A.S.S. and FLW tournament circuits.

A Product Line Built for Every Application

What truly differentiates Dual Pro in the battery charger category is the breadth and specificity of its product series. Each line is purpose-built for a distinct use case, so whether you're maintaining a weekend fishing boat or powering industrial equipment, there's a purpose-matched solution.

• RealPRO® Series: Designed for boaters who demand a truly waterproof onboard charger, the RealPRO is available in 1-, 2-, 3-, and 4-bank configurations. Compact and fully automatic, it's engineered to handle harsh marine environments while keeping trolling motor and starting batteries ready for action.
• Sportsman Series: Bridging the gap between entry-level and high-output charging, the Sportsman Series offers 10 amps per bank in 1- to 4-bank models. It features zero spark technology, fully automatic multi-stage charging, temperature compensation, and is rated for both fresh and saltwater use. Models are available for Wet Cell, AGM, and Lithium batteries.
• Professional Series: Dual Pro's flagship marine line, delivering 15 amps per bank in configurations up to 4 banks (60 amps total). The Professional Series features AUTOPROFILE technology, which automatically detects whether a battery is Lithium, AGM, or flooded lead-acid and adjusts the charging profile accordingly — no manual switching required. PROVolt™ models serve traditional Wet Cell and AGM applications with intuitive multi-stage charging.
• Eagle Performance Series: Built for golf carts, low-speed vehicles, scissor lifts, and industrial equipment, the Eagle Series combines heavy-duty transformer reliability with microprocessor control, temperature compensation, and a 3-year warranty. It supports 12V through 48V systems.

Technology That Protects Your Batteries

Across all series, Dual Pro chargers share a core set of intelligent features that make them more than just a power source. Each bank operates with an independent microprocessor and isolated output, meaning batteries of different sizes or states of charge can be connected simultaneously without interference. Delta Volt technology charges batteries faster to a full 100% state of charge with no risk of overcharging, while multi-stage charging algorithms condition and maintain batteries over time to maximize cycle life. Every model includes reverse polarity protection, short circuit protection, and ignition protection meeting U.S. Coast Guard standards.

For installations where flexibility matters, each output lead is extendable via available extension kits, and the fully potted, waterproof, vibration-proof construction means these chargers can be permanently mounted aboard vessels without concern for the elements. The result is a charger that owners regularly keep in service for decades — a testament to build quality that few competitors can match.
