The BMV-702 is a 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.

Models:6.5 – 95V

Midpoint voltage monitoring 
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.

Standard features
– Battery voltage, current, power, ampere-hours consumed and state of charge
– Remaining time at the current rate of discharge
– Programmable visual and audible alarm
– Programmable relay, to turn off non critical loads or to run a generator when needed
– 500 Amp quick connect shunt and connection kit
– Shunt selection capability up to 10.000 Amps
– VE.Direct communication port
– Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health
– Wide input voltage range: 6,5 – 95V
– High current measurement resolution: 10 mA (0,01A)
– Low current consumption: 2,9Ah per month (4mA) @12V and 2,2Ah per month (3mA) @ 24V

BMV-702 additional features
Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and
corresponding alarm and relay settings.

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 a Battery Balancer  to maximize service life of series-connected batteries.
