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 vehicle’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.
