The unit continuously monitors voltage, current (charge or discharge), numbers of amp hours, the battery 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 BM-1 compact is designed to monitor the performance of a 12 volt lead acid battery system with capacities of up to 600 Amp hours. It is supplied complete with a precision 100 Amp shunt and a prefabricated cable assembly 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 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 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-1 Compact consumes a miserly 1.5mA!
BM-1 Compact is used in various vehicles by the Ministry of Defence.
