DOL_NLBMS - Natinal Luna, Single Battery Monitor 

National Luna has developed single battery monitors which can be used in just about any 12-volt application. The monitors use digital technology and a simple-to-understand 14-stage colour display.

Great for monitoring your Caravan or Camper Trailer battery

The National Luna single battery monitors can be used for any installation that requires careful monitoring of lead-acid battery condition. These monitors use digital technology for increased accuracy and feature low-voltage and over-charge warnings.

The single monitor is available with or without audible alarms. Models with audible alarms have a mute option as well as display on/off option. A brand-new recessed version of the single monitor is available which is flush-mounting and can be used for permanent installations such as caravans, trailers, solar installations and boats
