Working mode (need to connect to 5V power supply)
AUTO-TEST automatic mode (boot default mode)
Start ¡æ charge (charge current is less than 0.12A, trigger full charge, stop charging) ¡æ discharge (load voltage is less than 2.7V, trigger discharge complete) ¡æ charge (charge current less than 0.12A trigger full charge, stop charging) ¡æ complete stop
¨çThe capacity and energy values are not recorded during charging, only timing.
¨èRecord the capacity and energy value when discharging, the same is timing.
CHARGE (charging mode)
Start ¡æ charge (the charging current is less than 0.12A to trigger full charge and stop charging) ¡æ complete stop
¨çOnly record the charging time, not the charging capacity and energy
DISCHARGE (discharge mode)
Start ¡æ discharge (load voltage is less than 2.7V, trigger discharge is completed ¡æ complete stop)
¨çRecord the discharge capacity, energy and time.
1: Specially used to measure 18650 battery capacity
2: The integration of charging and discharging eliminates the tedious operation of disassembling and assembling the battery to replace the charging and discharging of the device
3: The size of the discharge current can be switched and it is convenient to use
4: Small size, easy to carry
5: stable performance
This product is a 18650 battery capacity tester, which is specially used to measure the capacity of 18650 batteries. The 1.77-inch TFT display can simultaneously display information such as battery internal resistance, capacity, voltage, current, power, etc.; The tedious operation of charging and discharging equipment; preset three modes of automatic, charging and discharging, after selecting the corresponding mode, start the equipment, and the program will run automatically; the size of the discharge current can be switched for convenience.
technical parameter
¨çInstall the power supply 18650 battery and the 18650 battery to be tested;
¨èUse the Type-C data cable to connect the Type-C power supply port to the 5V power supply. The external power supply is used to charge the battery in the CHG state. If you only need to discharge the DSG, you can leave it unconnected;
¨éSelect the mode, the default is AUTO automatic mode;
¨êClick the Start button to start the program;
¨ëWait for the process to end and the status indication to stop.
About power-off storage:
This product has no power-off storage function. Shutting down, restarting, and switching the working mode can cause the accumulated data to be cleared (as shown below).
