Based on the highly successful BM-1 marine battery monitor, Nasa's BM-1 Compact is especially designed for applications where space is at a premium. Coming in at just 124 x 62mm x 23mm, small boats, caravans, mobile homes, RV's and renewable power installations can all benefit from the BM-1 Compact. The battery monitor is capable of monitoring the performance of any 12V lead acid battery system with a capacity up to 600 AmpHours. BM-1 continually monitors the voltage, 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 a more efficient use of the battery, enhancing its life and reducing the risk of failure.
Operation is very simple. One screen displays the voltage, current (charge or discharge) and a bar graph shows the remaining capacity. Furthermore, a flashing alarm is 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. BM1 compact does all of this whilst consuming a meagre one and a half milliamps.
