Victron Precision Battery Monitor BMV-700S 9-90Vdc with 500A
shunt

The BMV-700 is our newest 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.

  • Highest resolution: 10mA (0,01A) with 500A shunt.
  • Lowest current consumption: 1mA.
  • Easiest to wire: the BMV-700 comes with shunt, 10 meter RJ 12 UTP cable and 2 meter battery cable with fuse. No other components needed.
  • Easiest to install: separate front bezel for square or round appearance; ring for rear mounting and screws for front mounting.

The monitor display comes with both a round and square bezel, and fits a 52mm (2-1/16") hole. The shunt attaches between the battery and the ground connections, and a provided network cable connects the two. A fused wire (included) connects the shunt assembly to the positive battery terminal for voltage sensing.

The displays are:

Battery voltage: this readout is useful to make a rough estimation of the battery’s state-of-charge. Excessive voltage drops for a charged battery when under heavy load can also indicate that battery capacity is insufficient.

Starter battery voltage (BMV-702 only): this readout is useful to make a rough estimation of the starter battery’s state-of-charge.

Current: this represents the actual current flowing in to or out of the battery. A discharge current is indicated as a negative value (current flowing out of the battery). If for example a DC to AC inverter draws 5 A from the battery, it will be displayed as –5.0 A.

Power: power drawn fromthe battery in watts.

Consumed Amp-Hours: this displays the cumulative Ah consumed from the battery. A fully charged battery sets this readout to 0.0 Ah (synchronised system). If a current of 12 A is drawn from the battery for a period of 3hours, this readout will show –36.0 Ah.

State-of-charge: this is the best way to monitor the actual state of the battery. This readout represents the current amount of energy left in the battery. A fully charged battery will be indicated by a value of 100.0%. A fully discharged battery will be indicated by a value of 0.0%.

Time-to-go: this is an estimation of how long the battery can support the present load until it needs recharging.

Found this to be extremely usefull in knowing exactly what has come in (charged) and what has gone out (Amps drawn/consummed by the system/load).
