Smart Dual Battery Isolator Kit for RV, UTV, ATV, Truck, Boat

Our smart battery isolator, the 【DUAL BATTERY ISOLATOR KIT】, ensures balanced charging between two batteries, giving priority to the starting battery to prevent failures. Power flows to the auxiliary battery when the starting battery reaches full capacity at 13.3V, and the isolator cuts off current when the starting battery drops to 12.8V. The Dual Battery Kit with Voltage Sensitive Relay ensures that the primary battery is always charged and ready to start the vehicle.

The 【WIDELY APPLICATION】 of our Universal Dual Battery Isolator 12V Kit makes it the perfect versatile solution for all your automotive power needs, compatible with ATVs, boats, cars, mini-vans, trucks, RVs, and yachts, powering up your ride.

Featuring waterproof, dustproof, and vibration-proof properties, the 【BUILT TO LAST】 12V Dual Battery Isolator Kit is built to endure the most extreme weather conditions and terrains, delivering reliable protection for your power system.
