<p><strong>VICTRON ENERGY BAM030712200</strong>, is a battery monitor (fuel gauge) in black for battery, remaining time and much more with built-in Bluetooth. The battery's remaining capacity depends on the number of amp-hours consumed, discharge current, temperature, and battery age. Complex software algorithms are needed to take all these variables into account. In addition to the basic display options such as voltage, current, and amp-hours consumed, the BMV-700 series also shows state of charge, remaining time, and power consumption in watts.</p><p>The BMV-702 has an extra input that can be programmed to measure voltage (in a second battery), temperature, or mid-point voltage. To measure the current to and from the battery, a shunt is mounted between the battery's negative terminal and the loads or charger. The battery monitor has built-in Bluetooth, and you can check the battery's status via a smartphone, tablet, or laptop. All charger settings can be made with the VictronConnect app.</p><p><strong>Please note that you need a short negative cable between the outgoing negative terminal of the battery bank and the inside of the shunt; if you need to supplement with one, they are available under this link:&nbsp;</strong><a href="https://digital-skipper.se/tillverkare/oceanflex/fortent-kabel-fardigpressad"><strong>Pre-crimped tinned cable</strong></a></p><p><strong>Easy to install</strong><br>All electrical connections go to a quick-connect PCB on the current shunt. The shunt is connected to the monitor with a standard RJ12 telephone cable. Included: RJ12 cable (10 m) and battery cable with fuse (2 m), no other components are needed. Also included is a separate front bezel for a square or round display; a retaining ring for rear mounting and screws for front mounting.</p><p><strong>Very low power consumption from the battery</strong><br>Power consumption: 0.7 Ah per month (1 mA) @12 V and 0.6 Ah per month (0.8 mA) @ 24 V. Lithium-ion batteries, in particular, lose virtually all capacity when discharged to shutdown due to low voltage. After shutdown due to low voltage, a lithium-ion battery has a capacity reserve of approximately 1 Ah per 100 Ah of battery capacity remaining. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of, for example, 10 mA can damage a 200 Ah battery if the system is left in a discharged state for longer than 8 days.</p><p><strong>Features</strong></p><ul><li>Battery voltage, current, amp-hours, consumption, and state of charge</li><li>Remaining time at current discharge rate</li><li>Programmable visual and audible alarms</li><li>Programmable relay, to shut off non-critical loads or to run a generator when needed</li><li>500 amp quick-connect shunt and connection kit</li><li>Shunt with capacity up to 10,000 amp as an option</li><li>VE.Direct communication port</li><li>Stores a large number of historical events that can be used to evaluate consumption patterns and battery health</li><li>Wide voltage range 6.5 Ț"70 V</li><li>Current measurement with high-resolution rendering. 10 mA (0.01A)&nbsp;</li><li>"Extra" input for measuring voltage (of a second battery), temperatures or mid-point voltage and corresponding alarm and relay settings</li></ul><p><br></p><p><span class="fr-video fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="//www.youtube.com/embed/2vA-EjSSBVA?wmode=opaque" frameborder="0" allowfullscreen=""></iframe></span><br></p><p><strong>Good product-related links:</strong></p><ul><li><a href="https://www.victronenergy.se/panel-systems-remote-monitoring/bmv-712-smart" rel="noopener noreferrer" target="_blank">Manufacturer's product page</a></li><li><a href="https://www.victronenergy.se/upload/documents/Datasheet-BMV-712-Smart-SE.pdf" rel="noopener noreferrer" target="_blank">Datasheet</a></li><li><a href="https://www.victronenergy.se/upload/documents/Manual-BMV-700-700H-702-712-EN-NL-FR-DE-ES-SE.pdf" rel="noopener noreferrer" target="_blank">Manual&nbsp;</a></li></ul>
