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), battery temperature or midpoint voltage (see
below).
Bluetooth Smart
Use the Bluetooth Smart dongle to monitor your batteries on Apple or Android
smartphones, tablets, macbooks and other devices.
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-702 additional
features
Additional input to measure voltage (of a second battery), temperature or
midpoint voltage, and corresponding alarm and relay settings.

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 Battery Balancer (BMS012201000) to maximize
service life of series-connected
batteries.
