National Luna Battery Management Systems

 A flat battery is at best an inconvenience, at worst it could be a matter of life and death. Almost all emergency, utility and expedition vehicles have dual battery systems comprising a starter battery, auxiliary (2nd) battery and a management system.

The National Luna battery management system automatically prioritizes the charge from alternator to the starter battery when the engine is running and isolates the starter battery from discharge when the engine is switched off.

This means that appliances and accessories such as fridges, lighting and camera chargers that will be used when the engine is switched off do not discharge the starter battery preventing the vehicle from starting.

The Intelligent solenoid has been designed to be a compact, automatic, parallel split-charge isolator for 4x4 vehicles. It features intelligent control electronics and a low-loss, high-current solenoid rated for extreme environments.

Installing the Intelligent solenoid is simple as it piggy-backs off the vehicle's main battery without any ignition "tapping", ensuring that existing vehicle wiring is not tampered with.

National Luna dual-battery isolators work on a parallel charging principal, ensuring that there is minimal impact on your vehicle's charging system and electrical wiring.
