BMV-702 9 - 90 VDC, Black, Victron Energy

BMV-702 is a highly accurate battery monitoring device. The main function of the device is to calculate the power consumption and state of charge of the battery. The consumption in ampere-hours is calculated by integrating the current flow into or out of the battery.

MIDPOINT BLOOD PRESSURE MONITORING (BMV-702 ONLY)
This feature, which is often used in the industry to monitor large and expensive battery banks, is now for the first time available at a low cost to monitor any battery bank. A battery bank consists of a string of cells connected in series.

The middle voltage is the voltage halfway along the string. Ideally, the middle voltage would be exactly half of the total voltage. In practice, however, deviations will be observed, which depend on many factors, such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacitances and many others.

Large or increasing deviation of the median voltage indicates improper battery care or a failed battery or cell. Corrective action after a mid-voltage alarm can prevent serious damage to an expensive battery. Refer to the BMV manual for more information.
