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,
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 division 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.
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.
