60A Voltage Sensitive Relay - 12V Split Charge, Camper & Motorhome VSR

60A Voltage Sensitive Relay (VSR) — a high quality 12V voltage sensitive relay designed for split charging dual battery systems in campers, camper vans, motorhomes, caravans and marine applications. This relay automatically connects and disconnects a secondary battery based on system voltage, allowing safe charging of an auxiliary battery without risking discharge of the main starter battery.

When the charging voltage rises, the relay engages to charge the second battery. When voltage drops, it disconnects automatically, protecting the primary battery at all times. A built-in red LED indicator provides clear operational status.
