The National Luna Dual Battery Monitor is the ideal solution for monitoring two lead-acid batteries in a single system, such as those used in 4x4 vehicles and motorhomes. The digital technology of these monitors allows for precise tracking of the non-linear characteristics of lead-acid batteries.
A special feature of this model is the independent negative potential, which allows the use in vehicles with 24V systems. The dual battery monitors can be used either independently or in combination with any dual battery system.
The Dual Battery Controller is specifically designed to work with National Luna Split Charge Systems (Intelligent Relay or Portable Power Pack). This model allows the user to bypass the built-in timer of the split charge system, which is particularly useful when winching or jump starting when the main battery is too weak.
