High-Capacity 3-Bank Charging Performance

With a total output of 50 amps across three independently managed banks, the ProNautic 1250P is ideal for larger battery banks, lithium upgrades, and boats running multiple DC loads simultaneously.

Each bank is continuously monitored and adjusted, ensuring optimal charging whether powering starting batteries, house banks, or auxiliary systems.

Distributed-On-Demandâ„¢ Technology

Distributed-On-Demandâ„¢ Technology automatically senses battery demand and intelligently distributes available charging current. The charger can direct up to full output to a single depleted bank or balance power across multiple banks as conditions change.

This adaptive approach reduces charging time while improving efficiency and battery longevity.

ProMar Digital Charging Performance with 12 Selectable Profiles

This Promariner marine battery charger features up to twelve digitally controlled, precision four-stage charging profiles, including Charge, Condition, Auto-Maintain, and Recondition modes.

Battery chemistry support includes:

  • LiFePO4 lithium
  • Flooded lead-acid
  • AGM
  • GEL

The charger is factory-set for sealed batteries, with easy selection for other chemistries to match your system.

Global AC Input with Power Factor Correction

The ProNautic 1250P supports auto-ranging global AC input from 100–240V at 50/60Hz. Integrated Power Factor Correction reduces harmonic distortion and improves overall efficiency, allowing more usable AC power onboard while drawing less from shore power or generators.

Conservation Energy Saver Mode

Once batteries are fully charged and conditioned, the charger automatically enters Conservation Energy Saver Mode. In this mode, it monitors battery status and only supplies power when needed, reducing AC consumption and lowering long-term operating costs while maintaining a full state of charge.

Intelligent Diagnostics and Battery Health Protection

Advanced digital intelligence provides:

  • Self-test diagnostics
  • Real-time system voltage and amperage monitoring
  • Discreet fault indication
  • Automatic battery health reconditioning after extended Auto-Maintain periods

This proactive management helps identify issues early and extend battery service life.

Quiet Operation with Advanced Cooling Design

Automatic fan speed control ensures quiet operation under varying loads. The front-exhaust cooling design prevents airflow restriction and promotes efficient thermal management without excessive noise.

Temperature Compensation and Built-In Safety

The ProNautic 1250P includes automatic temperature compensation and ships with a remote temperature probe. Ignition protection, current limiting, and compliance with Marine ULc 1236, CE, CTick, FCC Class B, and CEC standards make it suitable for demanding marine environments.

Optional Remote Control and Display

For enhanced system visibility, the charger supports the optional ProMariner 63100 Remote Control and Display. This accessory enables remote monitoring of charging status, diagnostics, and system performance from a convenient location onboard.

Built for Long-Term Marine Reliability

Specifications:

  • System Voltage: 12V
  • Output: 50A total / 3 banks
  • Weight: 7.76 lbs
  • Dry-mount installation
  • 5-Year Warranty

As a flagship Promariner charger, the ProNautic 1250P is engineered for boat owners who require maximum charging capacity without compromising efficiency, safety, or control.
