About 18650 battery

The minimum discharge stop voltage of 18650 battery is generally: 2.75V. Under normal cirstances, when the voltage drops to 0.875 times the rated voltage (3.24V)

It should be charged, and then continue to use, the voltage will drop rapidly, there may be over-discharge and damage, affecting the life. (Recommended discharge termination

(The voltage is set to 3.5V)

The charging voltage is generally: 4.20V-4.3V/4.35V.

Measurement time calculation

Auming that the battery capacity is 2000mAH, the discharge current of this is about 500mAH, (2000:500=4), and the measurement time is about 4 hours

about.

list

1* module

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 (power supply is self-contained, just use a mobile phone charger.) The charging mode (Charge) and the 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 (pack),

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

Safety reminder: The load will release a high temperature of 60~80℃ during discharge. Keep ventilation when using it, avoid getting close to and explosive substances, and notify you to pay attention to safety and avoid burns.

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

AUTO-TEST automatic mode (power-on default mode)

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

①The capacity and energy value are not recorded during charging, only the time is counted.

② Record the capacity and energy value during discharge, both are timing.

CHARGE (Charge Mode)

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

①Record the discharge capacity, energy and time.

Note:

①During the discharge proce, as long as it detects that the battery load voltage drops to 2.7V, the discharge will stop. After the discharge is stopped, the battery is no-loaded, 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 start of self-discharge to trigger the stop of discharge. The capacity released by the first-stage battery can be simply understood as a single usable capacity, rather than the rated battery capacity.

② Shut down and restart; switch modes; long pre the start on to clear all data, and shutdown does not save historical data.

③Test ① install 18650 battery for testing, Test ② use type-c external or ≤5V power supply for testing, but Test ① and Test ② cannot be used for testing at the same time, to avoid accidents caused by overshoot of 18650 battery without protection.

④ To run the charging mode, an external working power supply is required.
