BM21 Smart Battery Monitor
The BM21 Smart Battery Monitor is a high-precision meter that allows you to check the status of your battery via your smartphone with the smart battery monitor app.
Through the use of a 75A/150A/500A current shunt, the battery monitor measures the discharge or recharge currents and calculates the Ampere-hours (Ah) going in and out of the battery.
High-precision voltage measurements are taken and displayed in real-time through the use of a field-installed sense wire. BM21 Smart battery monitor is well-suited for lithium, lithium Ion,
lead-acid and nickel-metal hydride batteries.
