Features Useful Battery Monitor: The car battery tester can measure voltage, current, power, charge and discharge capacity, watt hour, time and other parameters. You can also set it for overvoltage protection, undervoltage protection, overcurrent protection. Premium Design: Battery monitor shortcut keys are made of silicone material, which not only simplifies operation steps, but also feels comfortable. Acrylic panel design can effectively protecting the screen, easy to clean, dustproof and better light. Built in Buzzer: When a certain value of battery monitor exceeds the preset protection limit value, it will start the protection, and the alarm sound will sound and alarm, it will disconnect the circuit through the relay to protecting the instrument. Real Time Monitoring: Automatically recognize and monitor current in charge or discharge, in real time, which will largely improve the overall safety. Applicable Scenario: Voltage tester has 2.4in color display to show current function menu, parameter setting and measurement data, display information is comprehensive and user friendly, clear to see charging and discharging. Whether its ternary lithium batteries or lithium iron phosphate, or other types of batteries, as long as the battery voltage is within the measured range, all will work.
