 HW-586 Battery Capacity Tester Board Module Digital Display 18650 Lithium Lead-Acid Battery Resistance Discharge Meter
Specification:
Power supply voltage: DC 4.5-6V (micro USB interface)
Working current: no more than 70mA
Discharge voltage: 1.00V-15.00V, resolution 0.01V
Termination voltage range: 0.5-11.0V
Support through current: up to 3.000A, resolution 0.001A
Maximum error of voltage measurement: 1%+0.02V
Maximum error of current measurement: 1.5%+-0.008A
Maximum battery capacity range: 9999Ah (1Ah=1000mAh) The larger value is switched by shifting the decimal point. When it is lower than 10Ah, it is displayed as X.XXX, when it reaches 10Ah, it is displayed as XX.XX, and so on.
Note: In order to improve the voltage measurement accuracy, this circuit is specially designed for DC bias. When the terminal is not connected, a very small voltage will be displayed, which does not affect the actual measurement. If you short-circuit the input terminal (absolutely 0V), it will 0 is displayed.
