GEREE 1.5V-12V Battery Capacity Meter Discharge Tester for 18650 Battery Li-ion Lithium Lead-acid Battery
[Product Information]
Lead-acid Battery voltage: DC4.5-6V (micro USB interface) ; Working current: less than 70mA. Supported by current: the maximum 3.000A resolution 0.001A.
The discharge voltage: 1.00V-15.00V resolution 0.01V ; Termination voltage range: 0.5-11.0V.
The maximum measurement error voltage: 1%+0.03V ; The maximum measurement error of current: 2%+-0.010A.
Note: this circuit in order to improve the voltage measurement accuracy, specially designed DC bias.when the terminal is what all don't pick will display a small voltage, does not affect the actual measurement.if you are short connected with the input terminal (absolute 0V) will display 0. To understand the principle can consult the superposition theorem in electrical engineering.
