Features: Can real-time display voltages, real-time current, real-time power, remaining capacity, use-time of a variety of physical parameters. The instrument uses 2.4-inch color LCD- as the display, displaying comprehensive data, clear, easy to observe. Detection of charging- and discharging users can easily detect bidirectional current, without changing the wiring direction. Using copper- shunt to collect current, safe, convenient and accurate. This instrument is very suitable for applications that require monitoring of output voltages and current, as well as battery charging- and discharging.
