Voltage relay, unique and sensitive mode offering flexibility to the sports car maintenance driver

Key Features: 1. The dimensions are compatible with the BF43x series of heavy-duty modular fuse boxes and battery switches, matching common products on the market. 2. Once the primary starter battery is sufficiently charged, it will also begin charging the secondary battery. 3. Surface or panel mounting options provide installation flexibility. 4. No voltage drop compared to battery isolation diodes (0.6V). 5. It features a robust fiberglass-reinforced nylon housing. Specifications: Features: The size is compatible with the BF43x series of heavy-duty modular fuse boxes and battery switches, matching common products on the market. Once the primary starter battery is sufficiently charged, it will also begin charging the secondary battery. A voltage-sensitive relay (VSR) is the best way to ensure you can always jump-start your dual-battery vehicle. Surface or panel mounting options provide installation flexibility. No voltage drop compared to battery isolation diodes (0.6V). It has a solid fiberglass-reinforced nylon casing. Specifications: Condition: Brand New Material: Nylon Color: Black Size: 7 * 7 * 6 cm / 2.8 * 2.8 * 2.4 inches Rated Voltage: 12V DC Combined/Open Voltage: 13.3V/12.8V DC Continuous Rated Current: 125A Intermittent Rated Current: 140A Power Consumption: 10mA (Standby) / 330mA (Active) / 0mA (Storage Mode) Certification: CE IP67 Package Weight: Approx. 234g Functional Features: Once the engine is off, the left-hand battery discharges to the upper left charging device, and the VSR disconnects when the battery voltage drops below 12.8V. The good starter battery will not discharge to the device. When the battery on your left isn't charging, it's dead. At least there's a small battery on the right that can start the engine.
