The BMV-702 is our newest 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.

Battery ‘fuel gauge’, time-to-go indicator, and much more
The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and
the age of the battery. Complex software algorithms are needed to take all these variables into account.
Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series
also displays state of charge, time to go, and power consumption in Watts.
The BMV-702 features an additional input which can be programmed to measure the voltage (of a second
battery), temperature or midpoint voltage (see below).
Easy to install
All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to the
monitor with a standard RJ12 telephone cable. Included: RJ 12 cable (10 m) and battery cable with fuse (2 m);
no other components needed.
Also included are a separate front bezel for a square or round display appearance, a securing ring for the rear
mounting and screws for the front mounting.
Easy to program
A quick install menu and a detailed setup menu with scrolling texts assist the user when going through the
various settings. Please consult the manual for details.
New: midpoint voltage monitoring (BMV-702 only)
This feature, which is often used in industry to monitor large and expensive battery banks, is now for the first
time made available at a low cost, to monitor any battery bank.
A battery bank consists of a string of series connected cells. The midpoint voltage is the voltage halfway along
the string. Ideally, the midpoint voltage would be exactly half of the total voltage. In practice, however,
deviations will be seen, that depend on many factors such as a different state of charge for new batteries or
cells, different temperatures, internal leakage currents, capacities and much more.
Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or
cell. Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery.
Please consult the BMV manual for more information.
