Simple, Smart & Reliable Power Management

Microprocessor in-built: monitor voltage, current, and temperature.

BAYWATT 12V 200A Dual Battery Isolator Relay (also known as a Split Charge Relay), a cost-effective solution for managing dual batteries in your boat. This essential component offers a reliable and straightforward approach to onboard power distribution:

  • 🔌 Preserves Starting Power: Protects your primary battery from accidental discharge by secondary electrical systems, ensuring your engine always starts.
  • 🔋 Extends Battery Life: Prevents over-depletion of your secondary battery, maximizing its lifespan for longer enjoyment of onboard electronics.
  • Surge Protection: Shields your electrical system from damaging voltage spikes caused by sudden power fluctuations.
  • 🛠️ Easy Installation: Clear instructions and a user-friendly design simplify the installation process.
  • 📊 Reliable Performance: Built with high-quality materials for extended service life in harsh marine environments.

The BAYWATT 12V 200A Dual Battery Isolator Relay is a crucial component for anyone looking to maintain a dual battery system effectively, providing peace of mind and reliable power management for various applications.

How it Works:

The BAYWATT 12V 200A Dual Battery Isolator Relay operates like an electronic switch, controlled by a low voltage signal. Here's a simplified breakdown:

  1. Engine Off: The relay is inactive, isolating the starter battery from the secondary battery.
  2. Engine On: A low voltage signal (typically from the ignition or alternator) activates the relay.
  3. Power Flow: The relay connects the starter battery and secondary battery, allowing the alternator to charge both batteries simultaneously.
  4. Engine Off: The relay deactivates, isolating the batteries again.

Smart Battery Isolator (VSR) vs. Dual Battery Isolator Relay

Both the BAYWATT 12V 200A Dual Battery Isolator Relay and a Smart Battery Isolator (VSR) are designed to manage dual battery systems, but they operate differently and offer unique benefits:

  • Dual Battery Isolator Relay: This device functions as a simple on/off switch activated by a low voltage signal. It is highly reliable and straightforward, making it a cost-effective solution for basic dual battery management needs.
  • Smart Battery Isolator (VSR): A VSR (Voltage Sensitive Relay) automatically senses the voltage levels of the batteries. When the primary battery reaches a certain voltage, indicating that it is fully charged, the VSR connects the secondary battery to the charging system. This provides a more advanced and efficient way to ensure both batteries are optimally charged without manual intervention.

We Recommend:

  • 💰 For cost-effectiveness and simplicity: The 12V 200A Dual Battery Isolator Relay is a reliable choice.
  • ⚙️ For advanced features and compatibility: Upgrade to a Smart Battery Isolator (VSR) Ref BI12140
