Compact battery monitor, just 124 x 62mm x 23mm!

Caravans, mobile homes, RV’s, small boats and renewable power installations can all benefit from the BM-2 Compact. It is able to monitor the performance of any 12 Volt lead-acid battery system with a capacity of up to 600 amp-hours. The BM-2 Compact is supplied with a precision 200 Amp shunt and prefabricated cables to enable simple DIY installation.

The unit continually monitors the voltage, the current (charge or discharge) and calculates the state of charge together with the time remaining to charge or discharge the battery.

This information can lead to more efficient use of the battery enhancing its life and reducing the risk of failure.

The operation is very simple. One screen displays the voltage, current (charge or discharge) and a bar graph showing the remaining capacity. A flashing alarm is also included to warn if the capacity is getting too low. A second screen shows the remaining time available at the current charge/discharge rate together with the remaining capacity in both analog and digital format.

The BM-2 Compact consumes a miserly 1.5mA!
