18650 Lithium Battery Capacity and Internal Resistance Tester, Cycle Charge Capacity Analyzer/Capacity Measurement/Internal Resistance Measurement, Type C Power Interface

Warning: Keep the product away from children's toys and other items to prevent accidental ingestion or choking by children. This product supports single-channel internal resistance and capacitance measurement; it supports charging and up to 9 charge/discharge cycles in automatic mode. It can be used not only to charge the battery but also to measure the battery's internal resistance and capacitance. Most importantly, it can be used to distribute battery capacity and perform cycles.
Features: Digital Display: The 1.77-inch digital display clearly shows real-time voltage, real-time current, real-time power, stored capacity, stored energy, status indicator, operating mode, discharge cutoff voltage, number of cycles, internal battery resistance, and accumulated time. Multifunctional Design: It can not only be used to charge the battery, but also to measure the battery's internal resistance and capacity. Most importantly, it can be used to distribute battery capacity and perform cycle counting. Three Operating Modes: Automatic preset, three charging and discharging modes. Select the corresponding mode, and the program will run automatically. The discharge current can be switched for ease of use. Charging Function: External 5V power supply, maximum current 1A via the charging chip during charging. The charging process will record the capacity and energy level during charging. (Not suitable for charging LiFePO4 batteries.)
Internal Resistance Test: The product uses a 2-wire DC method to test the internal resistance of the battery, with high accuracy when the battery is fully charged.
Capacity Test: The capacity test is performed by resistance discharge. The results only show the capacity measured between the start of battery discharge during the test phase and the trigger's stop. The cumulative capacity, energy, and time are recorded during the discharge process.
Battery capacity division and operating cycle: The battery capacity division and operating cycle is a process of charging, discharging, and recharging. The stop voltage must not be less than 2.8V during use; otherwise, it cannot be charged, and the program cannot function correctly.
Data Clear Function: Automatically resets capacity, energy, and time data when the device is turned off and the mode is changed.
Language Switching: Dual-language design; the default language is Chinese, but you can freely change it according to your preference.
