The BMV-702 is Victron's new high precision multi-function battery monitor with a host of useful features. It essentially acts as a battery 'fuel gauge' for anyone needing to keep a check on the performance of their battery or battery bank and can monitor the voltage of a 2nd battery. The information displayed by the BMV-702 includes voltage, current draw, Ah consumed, % charge level, 'time-to-go' and it features a programmable alarm and in-built relay to trigger external equipment under an alarm condition (note: information displayed for 2nd battery is voltage only).

Installation is easy and all required connection cables are supplied. The shunt is fitted in-line with the leisure/house battery's negative cable, the starter/auxiliary battery's negative cable is connected to the shunt's output and fused +ve supplies are taken  from each battery into the shunt's 2 inputs. Once the battery monitor is panel-mounted in a suitable location (with or without the supplied square bezel) it is connected to the shunt's PCB using a single RJ12 data/power cable and programmed using the on-board menu.

As an alternative to monitoring the voltage of a 2nd battery  the BMV-702 shunt's 2nd/auxiliary input can be used for the following:

  • Temperature monitoring of a single battery/bank using an optional temperature sensor. Battery capacity reduces as temperature increases so the sensor measurement can be fed into the monitor to adjust displayed capacity based on temperature.
  • Mid-point voltage monitoring of one bank of batteries connected in series (or banks of series-connected batteries joined in parallel). This allows detection of a bad cell or a bad battery which can potentially destroy the other connected batteries by over-charging. The voltages either side of the mid-point are compared and the deviation displayed in % and V, with a programmable alarm providing a warning that the deviation is too great.

Suitable for use in caravans, motorhomes, campervans, boats, expedition, industrial and commercial vehicles.
