Battery Internal Resistance Tester 1.77in LCD Display Modes Adjustable 18650 Lithium Battery Capacity Tester DC5V

Feature: 1. Scope of Application: This battery capacity tester is mainly used for test the capacity of 18650 battery, check for better using experience! 2. LCD Display: The 1.77in screen displays internal resistance, capacity, voltage, current, power and other information at the same time. 3. Modes Adjustable: Preset automatic and charging and discharging modes, and select corresponding modes after starting. 4. Data Reset: The power off, mode switch will make the data capacity, energy and time data automatically reset. 5. Working Instructions: Some components will produce local high temperature during charging and discharging during use. Please ensure that the use environment is open and free 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. 6. 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) 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 phosphate battery charging is not supported) Discharge Function: Support, automatically stop when conditions are met, and the discharge current 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 Discharge Current: Two circuit resistance, maximum current of about 1A, non adjustable, independent transformation not supported Power Off Saving: Only save the set parameters, not the measurement data. Package List: 1 x Battery Internal Resistance Tester Note: 1. Lithium iron phosphate 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 discharge resistance is not supported.
