Battery Monitor
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), battery temperature or midpoint voltage (see below).
Battery voltage, current, power, ampere-hours consumed and state of charge
Programmable relay, to turn off non critical loads or to run a generator when needed
Low current consumption: 2,9Ah per month (4mA) @12V and 2,2Ah per month (3mA) @24V

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 (with your smartphone!)
A quick install menu and a detailed setup menu with scrolling texts assist the user when going through the various settings.Alternatively, choose the fast and easy solution: download the smartphone app (Bluetooth Smart dongle needed)
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.
BMV-700HS: 60 to 385 VDC voltage range
No additional parts needed. Note: suitable for systems with grounded minus only (battery monitor is not isolated from shunt).
Other battery monitoring options
- VE.Net Battery Controller
- High voltage VE.Net Battery Controller: 70 to 350 VDC
- Lynx Shunt VE.Net
- Lynx Shunt VE.Can
More about midpoint voltage
One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual, section 5.2, for more information. We recommend our (BMS012201000) to maximize service life of seriesconnected batteries.
BMV-702 additional features
Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings.
