This is the latest version of the BMV Amp Hour Meter, now called the BMV702. It replaces the BMV602 that went before it by adding some new features (see below) It keeps track of current flowing in and out of a battery bank and uses a sophisticated algorithm to read out the state of charge of the battery in Percentage Remaining and Amp Hours Remaining. It also displays Volts and Amps, time to go, and Consumed Energy and keeps track of Historic Data including Battery Efficiency, Average Discharge, Deepest Discharge, Number of Cycles, Overvoltage, and Undervoltage Alarms.
Victron Energy BMV 702 battery monitor Monitors volts, amps, amp hours and time to go for a single battery bank. See our article: All about amp hour meters Reads voltage (only) for a second bank. Included shunt measures up to 500 Amps For use with DC systems from 12 to 90 volts Visual and audible alarms and programmable alarm 10 metre cable, connectors and fuse included. We can special order shorter cables for a small charge but it will delay your order. Special order cables come in 0.3m, 0.9m, 1.8m, 3m, and 5m Removeable bezel allows round or square face for display
Ease of Operation and Setup: By changing the way the buttons and menu works, operation is now easier. The use of scrolling text for the setup and history menus, simplifies matters. Now, you need no longer remember the meaning of H1, H2, H3 etc. The BMV-700 Series will first let the name of the chosen item scroll by, and then show you the value. For the more familiar user, the scrolling text can be skipped by pressing one of the buttons.
Improved Information: The read-out now includes Watts in addition to the basic information of Volts, Amps, Amp Hours, State of Charge and Time To Go. A SOC bar is also included in the bottom right of the read-out as you can see in my photo above. At the top left of the screen, in text, the display also shows which value you are monitoring. There are two new historical values also: total kWh discharged and kWh charged. Now there is also a new instant Watts read-out.
Increased Options: The BMV-602 had just one function for the secondary voltage: starter battery voltage. Now the BMV-702 has a choice of one of three things it can do with the second input:
1. measure starter voltage
2. measure mid-voltage (and give a warning if the battery string is getting out of balance)
3. measure the battery temperature
Note, this last one requires a temperature sensor accessory, which has to be purchased separately.
These modes also come with their own readouts and additional history values
• Improved LCD Read-Out
• Simpler Operation and Setup
• Retention of History Data
• SOC Indicator Bar
• Calculates Watts
• Computes kWh Charged and Discharged
• Temperature Monitoring (BMV-702)
• Mid String Voltage Monitoring (BMV-702)
• Auxiliary/Starter Battery Monitoring
• VE.Direct Communications Port
• Relay Invert Function
Clearer LCD Read-Out: The segments are bolder and larger, utilizing two LEDs for the backlight instead of one. By using a different LCD technology, this has increased the contrast. Whilst the changes are subtle, they make a tangible difference. The backlight now has the choice of an always on function, if desired, for low light conditions.
Retention of History Data: The memory of the history data is no longer lost with a loss of power to the monitor. The BMV-600 would lose all history data (H1 to H16) in such an instance. This is no longer the case with the BMV-700.
Integration with other Victron Products: Using the free Victron Remote Management (VRM) website portal, integrated system information via a Color Control GX can display your current system status and energy flow. The site is accessible via a web browser or by using the free iPhone and Android apps.

Other Improvements: The data connection on the back is now a proper socket, instead of a pin-header and can only be fitted one way. The new communications protocol is called the VE.Direct protocol which improves on the old BMV or text protocol, allowing the advanced ability to change settings, such as the programmable relay switching on and off. Note. All future small form factor Victron Products that are too small for a VE.Can Communications Port will use the new VE.Direct Communications Port, as now fitted to the BMV-700 series and MPPT 70/15 and 75/50.

If you add the Victron Energy Bluetooth Dongle you can read the information on your iPhone or Android device
If you need to locate the shunt in an exposed place where it might get knocked I recommend the Blue Sea 2719 as a housing for the shunt
