2.4 Inch Wireless Voltage Meter Ammeter Voltmeter Coulometer Battery Power Detector Battery Capacity Tester Real-time Battery Monitor

Features:
Wireless transmission of data to avoids interference caused by complex wiring between the display and the detection module.
The Hall sensor is used to realize non-contact detection of current, without breaking the line, safer, reliable and convenient.
Voltage, current, power, temperature, capacity, percentage of remaining capacity, and running time are displayed at the same time.
Reserve interface for charging and discharging double relays, 5 relay working modes can realize automatic disconnection and automatic closing of charge and discharge.
With charge overvoltage, discharge undervoltage, charge overcurrent, discharge overcurrent protections, over temperature protections function, low temperature protections function, with buzzeralarm prompt function.
With power-off memory function, it can record the number of AH and WH before power-off.
When charging, the percentage progress bar is switched to the color running water light display, and the display screen shows the breathing light flashing effect, which enhances the prompt.
With voltage, current, temperature waveform curve display function.
Chinese and English language selection, two display colors can be switched, suitable for different customer needs.
