Overland Journal "Editors Choice", 2008 Dual Battery System Comparison

Why use a Dual Battery System?
Losing power to your vehicle is a common concern. With all the latest equipment drawing on your battery system, you need to consider your electrical supply and how to manage it. Winches, lighting, laptops, GPS, fridges, and the like all demand a lot from your battery. A good solution is a dual battery system that can manage the load you put on it. National Luna Battery Management Systems are time tested, proven vehicle energy control equipment. From the harsh demands of Africa, National Luna offers a complete line of monitoring and control options. 

National Luna Portable Power Pack is a removable, compact battery box with built-in split-charge isolator, ideal for modern vehicles that cannot accommodate a second battery in the engine compartment. The design of the Portable Power Pack allows it to be used as a standby power pack for 12-volt appliances.

The Portable Power Pack features fused accessory plugs, a polarized high-power plug and built-in battery monitor with low-battery and over-charge warnings. The built-in plugs can be used for low-power accessories such as refrigerators, pumps, compressors, lights and other 12-volt electronic devices. The high-current input-output can be used for higher power requirements such as invertors or battery chargers. The built-in split-charge isolator is fully automatic and does not require additional hardware in the application vehicle.

The Dual Battery Controller Plugs into port provided in the portable power pack. Mounts on dash board or other accessible location to show charge and storage status plus allow over-ride if Aux battery is needed for starting purposes.  Sold separately.
