SMART START DUAL ISOLATOR

The Smart Start Dual Isolator automatically manages the charging of two batteries in your vehicle, ensuring your main battery is always protected. It allows your auxiliary battery to charge while driving and isolates it when the engine is off to prevent drain. Built for durability, it performs reliably in tough off-road, marine, and commercial environments. Ideal for dual battery setups in 4x4s, caravans, and work vehicles.
