Description

BMV-702 is Available in grey and black, please choose from the dropdown.

We are very much in love with these gauges having installed and used them ourselves. Below is the information from the manufacturer Victron but if you do have any questions about these gauges then please do get in touch. They are very different to a normal gauge in that there is barely anything actually going into the gauge itself, just an RJ12 plug (similar to your phone at home) and no need for any dash wiring at all as all the wiring is done at the battery where you install the shunt part of the product.

One thing to note is that the shunt installs inline with the negative side of the battery you want the most information from (usually the aux) so you need to make sure that you either have an aux terminal on the negative of the battery or a battery terminal clamp with a stud to fit cables to. You will need to make a small patch of earth cable where this wires inline also, we can make these to order.

We’ve included some photos of the gauge fitted to one of our Defenders in the side fascia of the double din kit we sell, please note that in order to fit the gauge here you have to do some filing to the ring of the gauge, this isn’t hard but if not the gauge sits outside the fascia (picture also shown).

If you do not have a double din kit then you can fit anywhere you have a 52mm gauge mount or anywhere you can drill a 52mm hole, the depth of the gauge is very very shallow and we can supply mounting fascia’s to fit these in our cubby box subwoofer enclosures, just get in touch.

Anyway….

 

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.

Standard features

– 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: 9,5 – 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.
