For different types of batteries, different voltages, new and old batteries, in order to better and easier to understand the use of the battery state and remaining capacity information, we developed these advanced battery monitors. Combined with complex software algorithms, we collect and calculate the voltage and current of a battery and display it with simple numbers and icons. Compared with other similar products on the market, LI-BM500 has the following advantages: Easy to program
Clear display interface and operation interface, combined with four physical buttons, easily set capacity, maximum voltage, minimum voltage, capacity alert to meet different needs.
Meanwhile, download the Android or IOS APP to do fast and easy settings.
Easy to install
Clear installed diagram, clear at a glance. The installation card with the monitor makes the installation hole position simple and clear.
Wireless, smart and simple
With the Bluetooth connection, to monitor the battery information on Android or IOS APP.


LI-BM500 smart battery monitor is designed for different kinds of batteries, to measure and monitor battery capacity, voltage, current and working time remaining. Color LCD screen combined with shunt is much easier to set up and use. Multiple parameters can be set to fully meet diverse usage needs. Android and IOS APP make it more convenient to know battery information.
