ZB2L3 DC 4.5-6V Battery Capacity Tester Module Li-ion Battery Discharge Analyzer
1. Support DC4.5-6V input range and accurately test the capacity of various small battery types.
2. High-precision digital display design, easy to use and more intuitive observation.
3. Electronic load function, simulates real usage scenarios, and the test results are more reliable.
4. Equipped with Type C interface, compatible with mainstream equipment, simple and convenient connection.
5. Small and portable design, suitable for laboratory, DIY and outdoor testing scenarios.
Power supply voltage: DC4.5-6V (micro USB/Type C)
Operating current: no more than 70mA
Discharge voltage: 1.00V-17.00V Resolution 0.01V
Termination voltage range: 0.5-14.5V
Supported pass current: no more than 3.500A resolution 0.001A
Voltage measurement error: less than 1% + 0.02V
Current measurement error: less than 1.2% +-0.002A
Battery capacity range: 9999Ah (1Ah=1000mAh) When the value is large, it is switched by decimal shift. 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.
1. The battery under test should be fully charged first;
2. Connect the positive electrode of the battery under test to the positive input, and the negative electrode to the negative input, and cannot be connected in reverse (connecting the reverse load with the load may damage the circuit)! Connect the load to the output positive electrode and the output negative electrode to the tester USB-pass working power supply (not powered by 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 formulate the appropriate termination voltage according to the full charge voltage of the battery, and it will flash and display 3 times before starting the test. It is necessary to manually formulate the termination voltage. Only press the "+" or "-" buttons in the battery voltage display state to modify it. The termination voltage is displayed at the beginning of P, and the subsequent voltage represents the voltage value, with a resolution of 0.1V. After setting, press "OK" to start the test;
4. After the test starts, the tester will turn on the electronic switch that controls the load. The test process data display will be displayed between the discharge capacity (Ah), the current discharge current (A) and the battery voltage (V). The display content can be quickly switched through the "OK" button. When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, display data stays on the capacity (Ah) and flashes quickly with the corresponding indicator light. At this time, the displayed capacity is the actual discharge capacity of the battery. Press "OK" to terminate the flashing and let the data display stabilize. Press the "OK" button again to restore to the power-on state, and you can replace the battery. Test the next section;
Supplement: During the test, you can exit the current test by pressing the button "+" and retain the discharged data. The tester returns to the voltage display state. At this time, the "+" and "-" buttons are allowed to modify the termination voltage and press "OK" to continue starting the test; or you can exit the current test by pressing the "-" button and clear the discharged data.
When the power is not supplied, keep holding the "OK" button and turn on the USB power. The tester enters the function settings. There are two settings in total. Use the "+" and "-" button to modify and "OK" button to enter the next item and save and exit:
Setting item 1: The automatic voltage recognition function "AUon"/"AUoF" means to enable/deactivate. After deactivate, please manually set the termination voltage, and the value set will be automatically saved together;
Setting item 2: The automatic wheel display function "ALon"/"ALoF" means to enable/deactivate. After deactivate, the displayed content will not be automatically switched during the test, and can only be switched manually.
Err1: Battery voltage is higher than 15V
Err2: The battery voltage is lower than the set termination voltage
Err3: The battery cannot withstand the load discharge current or the internal resistance of the line is too large
Err4: The current is too high (current exceeds 3.1A)
Err5: Improper use or wiring error has caused the equipment to burn and cannot be used (current sampling or control switch MOS burned)
1. If the battery is connected in the reverse direction, when the load is turned on and the load current is large (about >0.8A), the circuit switch tube may be damaged;
2. The factory has been calibrated and tested one by one, and the design has a secondary calibration function;
3. In order to improve the voltage measurement accuracy, this circuit specially designed a DC bias. When the terminal is connected without any connection, a very small voltage will be displayed, which will not affect the actual measurement. If you short-circuit the input terminal (at this time, 0V will be necessary). If you want to understand the principle, you can check the superposition theorem in electrical engineering.
