Page 6: Introduction
2.1. The battery monitor The BMV-700H is a battery monitor. It measures battery voltage and current. Based on these measurements, it calculates the battery's state of charge and the time to go. It also keeps track of historical data, such as deepest discharge, average discharge and the number of charge and discharge cycles. - Page 7 Manual - BMV-700H • GX Device, such as a Cerbo GX - for system and/or remote monitoring. • VE.Direct cable - to connect the battery monitor to a GX device. • VE.Direct to USB interface - to connect to the battery monitor via USB to a GX device or to the VictronConnect app.
