National Luna 12v Split Charger System

The National Luna 12V Split Charger System provides everything needed for a dual-battery installation: intelligent battery isolator, controller, cables, fuses, and battery terminals. This makes installing a second battery simple and safe, without interfering with the vehicle’s electrical systems. The intelligent battery isolator automatically detects when the main battery is fully charged and safely connects the auxiliary battery. The system prevents overloading, reverse polarity, and short circuits, protecting both the batteries and the alternator. The controller continuously displays the voltage of both the main and auxiliary batteries and alerts the user to low voltage or missing batteries. Additional features, such as timer override and LED alarms, offer optimal control and convenience, even in demanding applications like winches or solar panel setups. For added ease, a comprehensive instruction manual is included, guiding you step by step through the installation process.
