BS-200 12V 200A Dual Battery Isolator

Premium Smart Voltage Sensitive Relay (VSR)

The BS-200 Smart Battery Isolator is the ultimate solution for managing dual battery systems in high-demand environments. Designed for 12V DC systems, this microprocessor-controlled relay automatically manages the charging of your auxiliary battery from the vehicleโ€™s alternator while ensuring your primary starting battery is never depleted. When your engine is running and the starting battery reaches 13.3V, the BS-200 engages to charge both batteries. When the engine is off and voltage drops below 12.8V, it instantly isolates them to safeguard your engine's ability to restart.

RELIABILITY: Engineered with a heavy-duty 200A continuous rating and IP65 waterproofing to handle harsh marine and off-road environments.
