VEVOR 12 V dual battery isolator relay (VSR) kit – a reliable solution for boat and motorboat electrical systems when separate engine starting (starter) and auxiliary batteries are used. This kit allows both batteries to be charged efficiently while the engine is running, while also protecting the starter battery from discharge. This kit allows both batteries to be charged efficiently while the engine is running, while protecting the starter battery from discharging.
A voltage-sensitive relay automatically connects the batteries when the charging voltage rises to ~13.3 V and disconnects them when the voltage drops to ~12.8 V. This ensures that the engine starter battery is always ready to start, even when electrical equipment is in use. ~12.8 V. This ensures that the engine starter battery is always ready to start, even when electrical equipment is using power while the vehicle is stationary. The kit includes all the essential installation components.
The kit includes all the essential mounting components. They allow the system to be quickly and conveniently integrated into the boat's electrical circuit. The shock-resistant housing and IP65 protection class ensure reliable operation in wet, dusty, and vibration-prone environments.
