The Dual Pro RealPRO Series Battery Charger (RS2) is a premium, multi-purpose battery charging system engineered for boats, RVs, trucks, and off-grid power systems. With support for 12V and 24V battery banks, and the ability to charge 2 to 6 separate batteries, this versatile charger delivers a total of up to 12 amps of charging power while intelligently maintaining battery health and extending service life.
Designed for demanding marine environments and rugged mobile applications, the RealPRO RS2 combines smart charging technology with robust construction to keep your deep-cycle, starting, and auxiliary batteries fully charged and ready. Whether docked, parked, or on the road, this charger ensures reliable power management so you’re never left without energy when you need it most.
The RS2 features two independent 6-amp banks, providing a total output of 12 amps. This configuration is highly versatile:
24V Systems: Connect one bank to each of your two 12V trolling motor batteries in a series for a perfect 24V charge.
Dual 12V Systems: Charge your starting battery and your house/trolling battery simultaneously, ensuring both are topped off and ready for a full day on the water.
The RealPRO series utilizes a sophisticated multi-stage charging profile that goes beyond simple "trickle" charging.
Safe Charging: The system monitors the battery's state and adjusts current to prevent overcharging, which extends the overall life of your batteries.
Deep Recovery: It is designed to "wake up" and recover batteries that have been deeply discharged (down to 2.0 volts), a common issue when electronics are left on accidentally.
Marine chargers live in one of the harshest environments on earth. The RS2 is engineered to survive it:
100% Waterproof: The unit is fully potted and submersible, meaning it is impervious to salt spray, humidity, and direct water contact.
Ignition Protected: Meets USCG and ABYC standards, ensuring it is safe for use in gasoline-powered boat engine compartments.
Independent Banks: Because each bank is isolated, if one battery in your bank fails or has a weak cell, the charger will still properly charge the other battery.

Note: This charger is optimized for Flooded Lead Acid and AGM batteries. For Lithium (LiFePO4) applications, please verify your battery manufacturer's charging requirements.
"To ensure the longevity of your RS2, mount it in a location with adequate ventilation, even though it is waterproof. Heat is the enemy of any electrical component. Additionally, always check the inline fuses on the charging leads if a bank appears 'dead'—vibration from running in rough water can sometimes loosen these connections."
The Dual Pro RealPRO Series Battery Charger – RS2 is perfect for:
Marine vessels: Boats with multiple batteries for engines, house loads, trolling motors, and accessories
Recreational vehicles: RVs with chassis and coach battery systems
Off-road rigs and campers: Vehicles requiring reliable multi-bank charging
Work trucks and fleets: Vehicles with start and auxiliary power circuits
Backup power systems: Charging multiple battery banks in off-grid or standby applications
The RealPRO series combines intelligent charging algorithms with user-friendly operation and rugged durability. By automatically adjusting charging stages based on battery condition, the RS2 helps maximize battery life, improve performance, and reduce maintenance needs. Whether you’re powering electronics, refrigeration, lighting, or engines, this charger keeps your battery banks ready and optimized.
