Module parameters:
Power supply voltage: DC4.5-6V (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: maximum 3.000A resolution 0.001A
Voltage measurement maximum error: 1%+0.02V
Maximum error of current measurement: 1.5%+-0.008A
The maximum battery capacity range: 9999Ah (1Ah=1000mAh) The larger value 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, and so on
