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.

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.
