VICTRON BMV-702 Battery Monitor

The BMV-702 is a high precision battery monitor. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery.

The installation process is straightforward, involving connecting the provided shunt in the negative battery cable, mounting the monitor in a 52mm diameter hole, and connecting the necessary wires. For those who prefer surface mounting, an optional wall enclosure is available for a more customized setup
