18650 battery capacity tester LCD display (with charging function) type-c port

Test voltage: ≤5V

Display mode: 128×64px LCD

Capacity range: 99999mAh

Energy range: 99999mWh

Timing range: 999:59:59

Working battery: flat head 18650 battery

Power interface: Type-C

External working power supply: 5V 1A (the power supply is self-provided, you can use the mobile phone charger). The charging mode (Charge) and automatic mode (AUTO-TEST) need to be connected to an external working power supply for normal use.

Product size: 115×81×31mm (product); 150×100×40mm (packaging),

Product weight: 110g (including packaging); net weight 74g

Safety Ts: The load resistance will release a high temperature of 60~80℃ during discharge. Keep ventilation during use, avoid close to flammable and explosive materials, and notify you to pay attention to safety and avoid burns.

Working mode (need to connect to 5V power supply)

AUTO-TEST automatic mode (boot default mode)

Start → charge (charge current is le than 0.12A, trigger full charge, stop charging) → discharge (load voltage is le than 2.7V, trigger discharge complete) → charge (charge current le than 0.12A trigger full charge, stop charging) → complete stop

①The capacity and energy values are not recorded during charging, only timing.

②Record the capacity and energy value when discharging, the same is timing.

CHARGE (charging mode)

Start → charge (the charging current is le than 0.12A to trigger full charge and stop charging) → complete stop

①Only record the charging time, not the charging capacity and energy

DISCHARGE (discharge mode)

Start → discharge (load voltage is le than 2.7V, trigger discharge is completed → complete stop)

①Record the discharge capacity, energy and time.

Note:

①As long as the discharge proce detects that the battery load voltage drops to 2.7V, it will stop discharging. After the discharging is stopped, the battery will be no-load and the voltage will rise; a single discharge proce can only detect that the voltage drops to 2.7V for the first time after the self-discharge starts and triggers the stop of the discharge. The capacity released by the first-stage battery can be simply understood as a single usable capacity, rather than the calibrated battery capacity.

② Shut down and restart; switch modes; long pre the start on and the data are cleared, and the historical data will not be saved after shutdown.

③Test①Install 18650 battery for testing, Test②test by type-c external power or ≤5V power supply, but Test① and Test② cannot be used at the same time for testing, to avoid accidents caused by overshoot of 18650 battery without protection.

④To run the charging mode, an external power supply must be connected

1: Specially used to measure 18650 battery capacity

2: The integration of charging and discharging eliminates the tedious operation of disaembling and aembling 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 equment; preset three modes of automatic, charging and discharging, after selecting the corresponding mode, start the equment, and the program will run automatically; the size of the discharge current can be switched for convenience.

technical parameter

①Install the power supply 18650 battery and the 18650 battery to be tested;

②Use 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;

③Select the mode, the default is AUTO automatic mode;

④Click the Start on to start the program;

⑤Wait for the proce 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 aculated data to be cleared (as shown below).

Charge and discharge time reference:

AUTO (automatic mode): The battery (discharged in advance) is charged ~ the default current is about 1A to discharge 1704mAh ~ it is fully charged again to trigger the program to stop, which takes 437 minutes and 23 seconds.

DSG (discharge mode): When the battery is fully charged, it uses a current of about 1A to discharge 1681mAh, which takes 118 minutes and 55 seconds.

CHG (Charging Mode): The capacity and energy are not measured during charging, only the time is recorded, which takes 164 minutes and 51 second
