200A Universal Dual Battery Isolator VSR for Car RV ATV UTV Camper Truck Boat 12V-24V

1. Flexible Design: LED display, real-time monitoring of two battery voltages. If the engine cannot be started with the main battery, simply press the emergency button to activate the auxiliary battery to start the engine. 2. Intelligent Isolation Connection: Supports automatic connection voltage (5-second delay) 13.5V-16V (12V operating voltage), 27V-32V (24V operating voltage) and automatic disconnection voltage (5-second delay) 12.5V; overvoltage protection 16V/32V. 3. Reliable to Use: The 200A dual battery isolator ensures the main battery is always charged and ready to start the vehicle. It's like having two separate power sources for each battery and a single alternator. 4. Wide Application: With its small design, the voltage-sensitive relay can be widely used in various vehicles such as 12V and 24V cars, trucks, RVs, ATVs, UTVs, boats, vans, SUVs, caravans, and camping applications. 5. Easy Installation: The dual battery isolator is easy to use; only a power cord is required. It features pure copper terminals for easy connection and four mounting holes for easy installation. Specification: Item Type: Dual Battery Isolator Material: ABS + Copper + Metal Operating Voltage: 12V-24V Rated Current: 200A Application Introduction: Some vehicles typically require auxiliary batteries to power various devices. However, the auxiliary battery cannot be directly connected in parallel with the vehicle's original battery. Power outages can drain the original car battery, making it difficult to start the vehicle. On the other hand, when two batteries are charged together, the circuit is heavily loaded. Therefore, a battery isolator is necessary. A battery isolator, also called a split charge relay, uses the vehicle's power to charge the auxiliary battery and prevents the starter battery from being drained by the device when the engine is off. The auxiliary battery isolator will only allow the additional battery to charge at the rate the alternator can handle. Applicable models: dual battery systems such as cars, RVs, ATVs, UTVs, campers, trucks, boats, etc., to solve the problem of the main and auxiliary batteries discharging. Package list: 1 x dual battery isolator, 16 accessories, 1 manual
