Digital Multimeter Charge-Discharge Battery Tester DC 0-90V 0-20A Volt Amp Meter

Features: 
1.MULTIMETER: this multifunctional meter can measure DC voltage, current, power, charging capacity, time, and other physical quantities at the same time; can be directly used, no need shunt. 
2.MEASURE RANGE: Digital multimeter can messure voltage range DC 0-90V, current range 0-20A, power range 0-9.99KW, capacity range 0-999Ah, time range 0-99.9 hours. 
3.LCD COLOR DISPLAY: the voltage current power panel gauge adopts 1.8 inch LCD color screen, can be seen even under sunlight; LCD display will automatically turn off after two minutes if current less than 50mA, pressing any key can turn off, or it will wake up automatically when the current is greater than 50mA. 
4.DATA STORE: The battery tester can automatically save the parameters when the display power off; if the monitor module also needs to power off, press OK button can save the parameters. 
5.BIDIRECTIONAL DETECTION: it's bidirectional, can detect and display current of charging and discharging. Note: it can not detect current of two directions at the same time.
