DC5V Battery Internal Resistance Tester with LCD Display for Lithium Battery Capacity

DC5V Battery Internal Resistance Tester Battery Capacity Tester 1.77in LCD Display Internal Resistance Capacity Voltage Current Power for Lithium Battery Capacity Tester

DC5V Battery Internal Resistance Tester with LCD Display for Lithium Battery Capacity

Scope of Application: This battery capacity tester is mainly used for test the capacity of 18650 battery, check for better using experience! LCD Display: The 1.77in screen displays internal resistance, capacity, voltage, current, power and other information at the same time. Modes Adjustable: Preset automatic and charging and discharging modes, and select corresponding modes after starting. Data Reset: The power off, mode switch will make the data capacity, energy and time data automatically reset. Working Instructions: Some components will produce local high temperature during charging and discharging during use. Please ensure that the use environment is open and of cover. It is better to increase fan heat dissipation. In order to ensure that the battery clamp is firm, the 18650 battery tester is more suitable for flat head battery measurement. DIY Transformation: Firstly, add 21700 battery holder. Then, connect the battery outside the extension cable or crocodile clip for testing. Specification Item Type: Battery Internal Resistance Tester Material: PCB Screen Size: Approx. 1.77in / 4.5cm Working Power Supply: DC5V power supply or 18650 battery x 2 (shipped without battery) Applicable Battery: Suitable for all batteries that meet the requirements of stopping disvoltage of 2.5-3.5V and starting from 2.8V to 4.2V Power Supply Interface: Type C interface, power supply line self prepared (C port mobile phone line) System Language: Chinese (default), English Test Quantity: 1 way charging and discharging measurement (only right battery position) Internal Resistance Measurement: Support, use DC two wire method to test internal resistance Charging Function: Support, automatic cut off charging when fully charged (lithium iron battery charging is not supported) DisFunction: Support, automatically stop when conditions are met, and the discurrent is not adjustable Automatic Charging and Discharging: Support. The battery is fully charged at the end of automatic mode Cyclic Charging and Discharging: Support, 1 to 9 cycles adjustable (only supported in automatic mode) Status Prompt: Support Stop DisVoltage: 2.5V, 2.6V, 2.7V, 2.8V, 2.9V, 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 11 adjustable gears DisCurrent: Two circuit resistance, maximum current of about 1A, non adjustable, independent transformation not supported Charging Voltage: Controlled by a special battery charging chip, with a maximum of about 1A and a full voltage of 4.2V Power Off Saving: Only save the set parameters, not the measurement data Package List 1 x Battery Internal Resistance Tester How to Use Language Switching: The factory default Chinese interface allows you to switch the language interface freely. Press and hold the "Menu" key and turn on the machine. Release the "Menu" key 3 seconds after the screen backlight is lit, and wait for 10 seconds to shut down and restart! Test the internal resistance: load the tested battery on the right battery holder after starting the machine, wait for 10 seconds, and display the battery voltage and internal resistance test results 1. Install 18650 battery of power supply and 18650 battery to be tested; 2. Connect Type C power interface to 5V power supply with Type C data cable. The external power supply charges the battery in the CHG state. If only the DSG needs to be discharged, it can be suspended; 3. Select a mode. The default mode is automatic. 4. Click the "Start" button to start the program; 5. When the waiting process is over, the status indicator stops. Note 1. Lithium iron battery charging is not supported. 2. When using the extension wire to connect the test battery externally, the line resistance affects the internal resistance measurement, and the internal resistance test results have no reference value. After the transformation, only one battery can be tested at a time, and multiple batteries cannot be tested at the same time. The charging and discharging elements are matched with the software algorithm, and the modification of adding disresistance is not supported.
