Accurate measurement: In order to improve the accuracy of voltage measurement,Battery capacity testers circuit is specially designed for DC bias. When the terminal is not connected at all, it will display a small voltage, which does not affect the actual measurement.
Size:Discharge testers board size is 5x3.4 cm/1.97x1.34 inch, small, easy to carry and store.
Power supply voltage:Battery capacity meters power supply voltage: DC4.5-6V (micro USB interface), working current: less than 70mA. Supported current: no more than 3.000A resolution 0.001A.
Discharge voltage:Battery meter testers discharge voltage: 1.00V-15.00V, resolution 0.01V. Termination voltage range: 0.5-11.0V.
Battery capacity:Battery meters battery capacity range: 9999Ah (1Ah=1000mAh). When the value is large, it is switched by the decimal point shift. When it is lower than 10Ah, it is displayed as X.XXX, and when it reaches 10Ah, it is displayed as XX.XX..
