Li-ion Lithium Lead Acid Battery Capacity Meter Discharge Tester Analyzer

Specification: Power supply voltage: DC4.5-6V (micro USB connector) Operating current: Less than 70mA Discharge voltage: 1.00V-15.00V, 0.01V resolution Termination voltage range: 0.5-11.0V Supported current: Maximum 3.000A, 0.001A resolution Maximum voltage measurement error: 1% 0.02V Maximum current measurement error: 1.5% ± 0.008A Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value is switched by shifting the decimal point, when it is less than 10Ah will display X.XXX, up to 10Ah or more will display XX.XX, and so on. Board size: 50 x 37mm Finished size: 50 x 37 x 17mm (L x W x H maximum position size, contains copper foot height) Board net weight: 28g (including pillars) Resistor weight: about 27g (including cable) How to use: 1. The test battery should be fully charged. 2. Connect the battery positive to positive input, negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the positive output and negative output, power on the tester with micro USB power supply (not available desktop or laptop USB powered), then the battery voltage display.
