An affordable solution to manage dual batteries on your boat. This essential component provides a reliable and straightforward approach to onboard power distribution:
Protects your main battery from accidental discharge by secondary systems, ensuring your engine always starts.
Prevents excessive drain on your auxiliary battery, maximizing lifespan for onboard electronics.
Safeguards your electrical system against damaging power surges caused by sudden fluctuations.
Clear instructions and a user-friendly design simplify the installation process.
Built with high-quality materials for extended life in harsh marine environments.
The BAYWATT Dual Battery Isolator Relay 12V 200A is a crucial component for anyone looking to efficiently maintain a dual battery system, offering peace of mind and reliable power management for various marine applications.
The BAYWATT Dual Battery Isolator Relay 12V 200A acts as an electronic switch controlled by a low-voltage signal. Here’s a simplified breakdown:
The relay is inactive, isolating the starter battery from the auxiliary battery.
A low-voltage signal (typically from the ignition or alternator) activates the relay.
The relay connects the starter and auxiliary battery, allowing the alternator to charge both simultaneously.
The relay deactivates, isolating the batteries again.
The BAYWATT Dual Battery Isolator Relay 12V 200A and a Smart Battery Isolator (VSR) are both designed to manage dual battery systems, but they operate differently and provide unique advantages:
This device functions as a simple on/off switch triggered by a low-voltage signal. It is highly reliable and straightforward, making it a cost-effective solution for basic dual battery management needs.
A VSR (Voltage Sensitive Relay) automatically senses the battery voltage levels. When the main battery reaches a certain threshold, indicating full charge, the VSR connects the auxiliary battery to the charging system. This provides a more advanced and efficient way to ensure both batteries are optimally charged without manual intervention. Recommended product: Ref BI12140
💰 Cost-effectiveness & simplicity: the 12V 200A Dual Battery Isolator Relay is a reliable choice.
