The National Luna 12V Split Charger System is a complete turn key Dual Battery System. This kit includes an Intelligent Solenoid, one Dual Battery Controller, and all the necessary materials for installation. Please note that the battery and tray are not included.
The National Luna 12V Split Charger System allows you to maintain two or more batteries in your vehicle. The Intelligent Solenoid manages the charging of both batteries when the vehicle is running, and isolates them when the vehicle is off. This is all automatic. With the Dual Battery Controller, you are also able to monitor the status of the batteries and manually override the connection.
Wiring the dual battery system is simple because you do not need to modify your existing electrical system.
