Voltage Sensitive Relay
Ensure reliable and efficient battery management on your boat with our Voltage Sensitive Relay. Designed to simultaneously charge two batteries from a single alternator, this smart relay protects your starter battery and onboard electronics while simplifying your electrical system.
- Automatically connects both batteries for charging once the starter battery reaches 13.7 V (12V system) or 27 V (24V system)
- Separates batteries when engine is off and voltage drops below 12.8 V (12V) or 25.2 V (24V) to prevent unwanted discharge
- Protects starter battery from draining due to onboard electrical loads
- Eliminates voltage drop for efficient charging performance
- No current draw in standby mode, preserving battery life
- Easy installation with no need to alter alternator wiring
- Automatic voltage selection for both 12V and 24V systems
