Foocles Dual Battery Isolator Feature Box
Always put the starter battery at the front of the charge queue to prevent starting issues.
Isolate the starter and auxiliary batteries to prevent mutual deep discharge and extend their lifespan.
Suitable for lead-acid, AGM, gel, and lithium-ion batteries in 12V or 24V system configurations.
Robust, weatherproof casing designed to endure marine, off-road, and outdoor use.
Built-in LED lights provide instant visual confirmation of relay operation and charging status.
When alternator output voltage increases, the battery is automatically tied in; when it drops, it disconnects.
Application of Dual Battery Isolator
Foocles dual battery isolator is widely used in RVs, off-road vehicles, forklifts, marine vessels, emergency backup power systems, and off-grid energy management applications to guarantee uninterrupted power and keep the starter battery fully charged.
By leveraging smart voltage monitoring and rapid MOSFET switching, this isolator secures vital starting power and enables auxiliary batteries to independently power loads, significantly enhancing safety and convenience across automotive, boat, and backup applications.
Energy-Efficient MOSFET Technology
Using an integrated MCU/voltage comparator, Foocles dual battery isolator watches both battery voltages in real time. Once the generator voltage exceeds about 13.3 V, the MOSFET is turned fully on; below 12.8 V, it shuts off immediately, with zero dwell in the lossy region. So you can select an efficiency dual battery isolator for your application.
Rugged & Durable Material of Dual Battery Isolator
Foocles dual battery isolator is engineered from top-quality plastic that is shockproof and dustproof, ensuring peak strength, durability and years of reliable operation.
All cable components in our smart battery isolator kit are crafted from premium copper conforming to international standards, this guarantees the safety and reliability of your battery system.
After installation, Foocles dual battery isolator will automatically control the circuit based on voltage levels. For example, when you turn off your car, it will disconnect; when you start the engine, it will connect and charge the batteries. If you really want to manually control the switch, you can choose the FLS761 Voltage Sensing Relay (VSR).
When you go on an RV trip, you always need an auxiliary battery to power extra lights, a winch, a cab heater, and other devices. Dual battery isolator will keeps you from being “dead battery” stranded.
You can imagine the starter and auxiliary batteries are connected in parallel. The dual battery isolator is then installed on the positive line between the two batteries, with its negative terminal tied to the auxiliary battery’s negative post.
