BM-2 Compact is designed especially for applications where space is at a premium. It fully monitors performance of 12 volt lead acid battery systems with capacities of up to 999 Amp hours. The package is supplied complete with a precision 200 AMP shunt and a prefabricated cable assembly to enable simple DIY installation. The unit continuously monitors voltage current (charge or discharge) number of amp/hours (charge or discharge) the batteries state of charge and the time to charge or discharge. This information leads to more efficient use of the battery which can enhance battery life and reduce the risk of failure.

The minimum information required to monitor the state of charge of a battery is the terminal voltage and the charge/discharge current. The Nasa Clipper BM-2 Battery Monitor measures both these parameters and computes the state of charge using a complex well proven algorithm.

A simple and intuitive display shows the service battery voltage charge/discharge current state of charge and time to charge/discharge. Nasa Clipper BM-2 Baterry Monitor also warns the user when the charge level is too low so that load can be shed or charging commenced to protect the battery. A resettable Amp Hour counter is provided for checking the efficiency of the charging system or keeping a track of power consumption and a second input lets the user monitor the voltage of the starter batter. The simple display format does not mean the internal software is unsophisticated. In fact two separate algorithms are used. One based on integrating amp hours over the charge and discharge cycle the second based on an adaptive internal mathematical battery model.

A unique feature of the Nasa Clipper BM-2 Battery Monitor is its ability to use information from both algorithms during the charge/discharge cycles to continually update its performance. This means that unlike many other systems that rely solely on amp hour integration the Nasa BM-2 Battery Monitor never needs to be re-synchronised with the battery. The algorithm includes Peukert's equation to ensure accuracy over a wide range of load currents.
The Nasa Clipper BM-2 Battery Monitor does all this whist consuming a meagre one and a half milliamps. Nasa Clipper BM-2 is a true battery monitor easy to install and excellent value for money.
