2.5.1 Starter battery monitoring
In addition to the comprehensive monitoring of the main battery
system, the BMV-602S also provides basic monitoring of a second
battery. This is useful for systems such as those with a separate
starter battery. Unless otherwise indicated, all values and settings
described in this manual refer to the main battery system.
2.5.2 Use of alternative shunts
The BMV is supplied with a 500 A / 50 mV shunt. For most
applications, this should be suitable; however the BMV can be
configured to work with a wide range of different shunts. Shunts of up
to 9999 A, and/or 100 mV can be used.
2.5.3 Automatic detection of nominal system voltage
The BMV will automatically adjust itself to to the nominal voltage of the
battery.
During charging, the BMV measures the battery voltage, and uses this
to estimate the nominal voltage. The following table shows how the
nominal voltage is determined, and how the charged voltage
parameter Vc (see section 3.4.1) is adjusted as a result.

2.5.4 Interface options
To display BMV data on a computer: see the BMV Data Link RS232
with software.
There are several other options for communication. Please download
"Data communication with Victron Energy products" from our website
(Support and downloads White papers) for more information.
If you need the communication protocol to integrate the BMV into your
system, please contact your Victron dealer, or email
sales@victronenergy.com.
