HW-586 Battery Capacity Tester Board Module Digital Display 18650 Lithium Lead-Acid Battery Resistance Discharge Meter
Specification:
Power supply voltage: DC 4.5-6V (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: up to 3.000A, resolution 0.001A
Maximum error of voltage measurement: 1%+0.02V
Maximum error of current measurement: 1.5%+-0.008A
Maximum battery capacity range: 9999Ah (1Ah=1000mAh) The larger value is switched by shifting the decimal point. When it is lower than 10Ah, it is displayed as X.XXX, when it reaches 10Ah, it is displayed as XX.XX, and so on.
Note: In order to improve the voltage measurement accuracy, this circuit is specially designed for DC bias. When the terminal is not connected, a very small voltage will be displayed, which does not affect the actual measurement. If you short-circuit the input terminal (absolutely 0V), it will 0 is displayed.

Instruction:
1. The battery under test should be fully charged first.
2. Connect the positive pole of the battery under test to the positive input, and the negative pole to the negative input. Do not reverse the connection (reverse connection with load may damage the circuit)! Connect the load to the positive output and negative output, and power the tester's micro USB (not available for desktop or laptop USB), and the battery voltage is displayed at this time.
3. To start the test directly, you only need to press the "OK" button. The tester can automatically set a suitable termination voltage according to the full charge voltage of the battery, and it will flash for 3 times before starting the test. If you need to manually set the end voltage, you only need to press the "+" or "-" button to modify the battery voltage display state. The end voltage display starts with P, and the back represents the voltage value with a resolution of 0.1V. After setting, press "OK" "start testing.
4. After the test starts, the tester will turn on the electronic switch that controls the load, and the test process data display will be displayed in turn among the discharge capacity (Ah), the current discharge current (A) and the battery voltage (V). When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, the display data stays on the capacity (Ah) and flashes quickly with the corresponding indicator. The displayed capacity at this time is the actual discharge capacity of the battery, press it once "OK" can stop the flashing and make the data display stably, press the "OK" button again to restore to the just-
