Battery Monitor | Bluetooth – Round 500A
The BM21-500 Smart battery monitor is a high-precision meter that allows you to check the status of your battery via the display or your Smartphone with the smart battery monitor App.
Through the use of a 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. BM21-500 battery monitor is compatible with all types of batteries, especially lithium, LiFePO4 batteries.
