National Luna Dual Battery Monitors are ideal for monitoring 2 lead-acid batteries in a single installation such as dual-battery systems in 4x4's and campers. The digital technology used in the dual monitors allows the non-linear characteristics of lead-acid batteries to be accurately followed.
A feature of one of the National Luna dual battery monitors is the independent negative - allowing this particular model to be used in vehicles with 24V systems. Dual battery monitors can be used independently, or in combination with any dual-battery system.
The Dual battery controller is specifically designed to be combined with the National Luna split-charge systems (Intelligent Solenoid or Portable Power Pack). This model allows the user to over-ride the split-charge system's built-in timer, useful for winching or start assistance when the main battery is too low.
