The capacity remaining in the batteries depends on the ampere-hours consumed, the discharge current, the temperature and the age of the batteries. A complex software algorithm is required to calculate all these variables. The BMV700H Smart displays voltage, current and amp-hours, as well as charge status, remaining run time, and power consumption in watts.
All electrical connections are installed to the shunt. It connects to the monitor using a standard RJ12 telephone cable. The kit includes 10 meters of RJ12 cable and a battery power cable with fuse. No other components are required.
A quick installation menu and a detailed settings menu with accompanying text help with various settings. It can be monitored from any Bluetooth device - smartphone, tablet, computer, etc.
This battery monitor is only used for grounded negative systems. The display is not galvanically isolated from the shunt.
