Ardent Smart Battery Monitor with Bluetooth (Make Your Battery Bluetooth)

BM21 Smart Battery Monitor with Bluetooth Monitoring

The BM21 is the latest high precision battery monitor that monitors voltage and current of a single battery bank and calculates power, state-of-charge and time-to-go. It also features an additional voltage input that can be used to measure an auxiliary or starter battery voltage, midpoint voltage or temperature with the optional temperature sensor. Data can be transferred to smartphones or computers with the inbuilt bluetooth module and external alarms can be triggered with the relay contact.

Installation is simply a case of connecting the supplied shunt in the negative battery cable, mounting the monitor or use the included stand and connecting the wires.

• BMV - SMART READY DEVICE

  With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth being implemented in most other Energy products, wireless communication between products will simplify system installation and enhance performance.

• ELECTRONIC PROTECTION 

  High-precision voltage measurements are taken and displayed in real-time through the use of a field-installed sense wire. BM21 battery monitor is well-suited for lithium, LiFePO4, Lead-aid and nickel-metal hydride batteries.

• COMPLETE VOLTAGE FUNCTIONALITY 

  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 wiring diagram for more information. We recommend our Battery Balancer to maximize service life of series-connected deep cycle batteries.

• EASY TO USE

  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.
