This product supports single channel internal resistance and capacity measurement; supports charging and up to 9 charging-and-discharging cycles in automatic mode. It not only can be used to charging battery, but also can be used to measure the battery internal resistance and capacity. And more important, it can be used to dispense battery capacity and run cycles.
Features:
Digital Display: 1.77inch digital display, clearly display the real time voltage, real time current, real time power, accumulated capacity, accumulated energy, status indication, operating mode, stop discharge voltage, number of cycles, battery internal resistance and accumulated time.
Multifunctional Design: It not only can be used to charging battery, but also can be used to measure the battery internal resistance and capacity. And more important, it can be used to dispense battery capacity and run cycles.
Three Working Modes Design: Preset automatic, charging and discharging three modes, select the corresponding mode, the program automatically run, the discharge current can be switched for ease of use.
Charging Function: External 5V power supplys, maximum 1A current through the charging chip when charging, and the charging process will record the capacity and energy amount charging time. (Not suitable for charging LiFePO4 batteries.)
Internal Resistance Test: The product uses the direct current 2-wire method to test the internal resistance of the battery, with high accuracy when the battery is fully charged.
Capacity Test: The capacity test is carried out by resistance discharge, and the results are only the capacity measured between the starts of the battery discharge during the test phase and the trigger stops. The cumulative capacity, energy and time are recorded during the discharge process.
Battery Capacity Division and Running Cycle: The battery capacity dividing and running cycle is a process of charging, discharging and recharging. The stopping voltage cannot be lower than 2.8V when in use, otherwise it cannot be charged and the program cannot run properly.
Data Clear Function: Automatic zeroing of capacity, energy and time data when switching off and switching modes.
Language Switching: Two working languages design, the factory default language is Chinese, but you can freely switch according to your preference.
