ZB2L3 Battery Capacity Tester External Load Discharge Type Module 1.2-12V 18650 Battery Available Note: Using the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety! Please install the 50W aluminum resistance (has been soldered half part of high temperature line) to a metal plate to use! This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal connects nothing will display a small voltage, but does not affect the actual measurement, if you are shorting the input terminal (absolute 0V) will display 0. If you want to know the principle, you can check the superposition theorem of electrical engineering.
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.
