Taidacent 2PCS ZB2L3 Battery Capacity Tester Circuit External Load 1.2-12V Lithium Battery 18650 Equal Capacity Test Battery Capacity Meter Discharge Tester

Specification: 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 current through: maximum 3.000A resolution 0.001A Maximum voltage measurement error: 1% + 0.02V Maximum current measurement error: 1.2%+-0.002A The highest 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 is above 10Ah, it is displayed as XX.XX, and so on. Board size: 50mmX37mm Finished product size: 50mmX37mmX17mm (length X width X height maximum position size, including copper foot height) Board and accessories weight: single board 28g (including copper column), two 5W ceramic resistor 9g, 50W resistance about 27g (including line) Note: In order to improve the voltage measurement accuracy, this circuit specially designed the DC offset. When the terminal is not connected, it will display a small voltage, which does not affect the actual measurement. If you short-circuit the input terminal (absolute 0V), it will display 0. . If you want to understand the principle, you can check the superposition theorem in electrical engineering. During the use of resistance discharge, the resistance load will be severely heated, please pay attention to safety! 50W aluminum shell resistor (has been welded a high temperature wire), please install it on the metal plate!
