RecPro 55 Amp RV Power Converter & Battery Charger — 12VDC Output, 4-Stage Charging for Lead & Lithium

The RecPro 55 Amp RV Power Converter & Battery Charger converts 120VAC shore power into stable 12VDC and delivers four-stage charging to maintain both lead and lithium RV batteries.

This compact converter/charger is designed for RV owners who need dependable onboard power management while plugged into shore power. It supplies continuous 12VDC to lights and appliances and simultaneously charges your RV battery using an intelligent four-stage algorithm that adapts to battery type. Built to fit common RV electrical bays, the unit balances everyday loads with battery health features so systems run efficiently when you’re parked or preparing for transit.

How does this unit keep my RV systems running while plugged in?

The RecPro 55 Amp converter provides a steady 12VDC output whenever your RV is connected to 120VAC shore power, so lights, fans, and low-voltage appliances remain powered without draining the battery. The converter isolates and stabilizes voltage to protect sensitive electronics from fluctuations.

• 55 amp continuous 12VDC output for multiple circuits
• Maintains voltage under typical RV loads like lighting and water pumps
• Protects devices by conditioning incoming AC to stable DC

Will it charge my battery type and how does the 4-stage charging work?

The built-in four-stage charger supports both lead-acid and lithium batteries by automatically cycling through bulk, absorption, float, and equalization/maintenance phases as appropriate. This approach optimizes charge speed and extends useful battery life by preventing overcharge and minimizing long-term sulfation or imbalance.

• Bulk stage supplies high current for rapid charging
• Absorption stage reduces current as voltage approaches full charge
• Float stage maintains full charge without overcharging
• Maintenance/equalization balances cells when needed

What installation and connection features should I expect?

RecPro designed the 55 Amp unit for straightforward mounting in common RV electrical compartments with clearly labeled AC and DC terminals. The converter includes protected wiring points and a compact footprint to make retrofit or replacement simpler for DIYers and technicians alike.

• Standard mounting flange and screw locations for easy replacement
• Labeled AC input and DC output terminals for clear connections
• Thermal protection and ventilation paths to manage heat

How does this model compare to other RecPro capacities?

The 55 Amp option sits mid-range among RecPro converters, offering more charging and system power than 35A or 45A units while being smaller and lighter than 75A and 100A models. Choose 55A if you have moderate onboard loads and a typical single-battery or dual-battery setup that needs reliable charging when shore power is available.

• Better suited than 35A/45A for heavier lighting and accessory loads
• Less bulky and lower cost than 75A/100A for smaller RVs
• Balances charging capability and compact installation needs

Who is this product for: The RecPro 55 Amp RV Power Converter & Battery Charger is aimed at RV owners and fleet managers who need dependable shore-power conversion and smart charging for either lead-acid or lithium house batteries. It fits owners of mid-size travel trailers, fifth-wheels, and motorhomes who want an easy-to-install, four-stage charging solution that supports everyday onboard systems without upgrading to a heavy-duty commercial converter. If you run multiple lights, pumps, and small appliances while boondocking part-time or parked at campgrounds, this model provides a practical balance of continuous DC power and battery maintenance features to keep your electrical system stable and ready.
