Features Digital Yacht’s BM100 battery monitoring system allows highly accurate DC voltage, current, and capacity measurements, enabling reliable monitoring of your boat’s battery and electrical system. Core to the system is the SmartShunt. It measures battery voltage and current. Based on these measurements, it intelligently calculates the battery’s state of charge and the time to depletion for the remaining charge. It also keeps track of historical data, such as the deepest discharge and average discharge current, as well as the number of charge and discharge cycles. The smart shunt can also monitor the voltage of a 2nd battery, typically dedicated to engine starting. The product is a collaboration between Victron Energy and Digital Yacht. The system utilizes Victron’s proprietary VE.Direct data connectivity as a source for the NMEA 2000 data. The BM100 is part of a wider group of products now introduced by Digital Yacht that bring NMEA 2000 connectivity to Victron systems using the VE.Direct interface. Victron solar panel controllers (MPPTs) and battery monitors can now also interconnect to NMEA 2000 via the veKonvert interface. Monitoring the battery with the BM100 will give important feedback to the user so that remedial measures can be taken when necessary. Doing this will extend battery life. There’s also an optional battery temperature sensor available. The BM100 can also integrate with Digital Yacht’s other NMEA 2000 and wireless instruments, which offer hybrid NMEA 2000 and wireless display options. NMEA 2000 Interface The system features an NMEA 2000 interface, so your navigation multi-function display or plotter can display all key parameters.

Smart Battery Monitor - BMV-712 - Grey - Bluetooth Capable Features: Bluetooth inside With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth being implemented in most other Victron Energy products, wireless communication between products will simplify system installation and enhance performance.  Download the Victron Bluetooth app Use a smartphone or other Bluetooth enabled device to - customize settings, - monitor all important data on single screen, - view historical data, and to - update the software when new features become available.  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 rear mounting and screws for front mounting.  Midpoint voltage monitoring One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual, section 5.2, for more information. We recommend our Battery Balancer (BMS012201000) to maximize service life of series-connected lead-acid batteries.  Very low current draw from the battery Current consumption: 0,7Ah per month (1mA) @12V and 0,6Ah per month (0,8mA) @ 24V Especially Li-ion batteries have virtually no capacity left when discharged until low voltage shutdown. After shutdown due to low cell voltage, the capacity reserve of a Li-ion battery is approximately 1Ah per 100Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10mA for example may damage a 200Ah battery if the system is left in discharged state during more than 8 days.  Bi-stable alarm relay Prevents increased current draw in case of an alarm.  Other features - Battery voltage, current, power, ampere-hours consumed and state of charge - Remaining time at the current rate of discharge - Programmable visual and audible alarm - Programmable relay, to turn off non critical loads or to run a generator when needed - 500 Amp quick connect shunt and connection kit - 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: 6,5 – 70V - High current measurement resolution: 10 mA (0,01A) Warranty Info WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.

Compact battery monitor, just 124 x 62mm x 23mm! Based on the highly successful BM-1 marine battery monitor, the BM-1 Compact is especially designed for applications where space is at a premium. Caravans, mobile homes, RV's, small boats and renewable power installations can all benefit from the BM-1 Compact. It is able to monitor the performance of any 12 Volt lead acid battery system with a capacity up to 600 AmpHours. The BM-1 Compact is supplied with a precision 100 Amp shunt and prefabricated cables to enable simple DIY installation. The unit continually monitors the voltage, the current (charge or discharge) and calculates the state of charge together with the time remaining to charge or discharge the battery. This information can lead to a more efficient use of the battery enhancing its life and reducing the risk of failure. Operation is very simple. One screen displays the voltage, current (charge or discharge) and a bar graph showing the remaining capacity. A flashing alarm is also included to warn if the capacity is getting too low. A second screen shows the remaining time available at the current charge/discharge rate together with the remaining capacity in both analog and digital format. The BM1 Compact consumes a miserly 1.5mA!This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.

BM-1 LI Battery Monitor for 12V Lithium The BM-1 battery monitor is designed to monitor performance of 12 volt lead acid battery systems, including AGM and GEL types with capacities of up to 600 Amp hours. It is supplied complete with a precision 100 AMP shunt and a prefabricated cable assembly to enable simple DIY installation. The unit continuously monitors voltage, current (charge or discharge), number of amp/hours (charge or discharge), the batteries state of charge and the time to charge or discharge. It also monitors the voltage of the engine strat battery. This information leads to more efficient use of the battery, which can enhance battery life and reduce the risk of failure. Features: Fully monitors domestic battery/bank Monitors voltage of engine start battery Specifications: Supply Voltage BM-1  12V 8 – 16 Volts DC BM-1  24V 16 – 32 Volts DC Supply current 1.5 milliamps Battery capacities 5 – 600 AMP Hour Load current 100 AMPS Maximum Charge current 100 AMPS Maximum Shunt Standard 50 millivolt @ 100 AMP Cables Supplied: 100 AMP shunt link to M8 Ring terminal. 5 Metre from display unit to battery – fused and fitted with ring terminals for shunt, fuse holder and M8 ring terminal to battery. Display unit Standard 110mm square Clipper case. High contrast LCD, backlit for night viewing. Minimum voltage visual alarm Simple operation – 4 keys to select backlight, Volt/Amp/State of Charge screen, AMP hours or Time to run. How Does It Work? A simple and intuitive display shows the service battery voltage, charge/discharge current, state of charge, and time to charge/discharge. The instrument also warns the user when the charge level is too low so that load can be shed or charging commenced to protect the battery. A resettable Amp Hour counter is provided for checking the efficiency of the charging system or keeping a track of power consumption and a second input lets the user monitor the voltage of the starter battery. The simple display format does not mean the internal software is unsophisticated. In fact two separate algorithms are used. One based on integrating amp hours over the charge and discharge cycle, the second based on an adaptive internal mathematical battery model. A unique feature of the BM1+ is its ability to use information from both algorithms, during the charge/discharge cycles, to continually update its performance. This means that, unlike many other systems that rely solely on amp hour integration, the NASA BM1+ never needs to be re-synchronised with the battery. The algorithm includes Peukert's equation to ensure accuracy over a wide range of load currents. The BM1+ does all this whist consuming a meagre one and a half milliamps. It is a true battery monitor, easy to install and excellent value for money. This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
