Comparison of internal resistance test accuracy：

The product uses the DC 2-wire method to test the internal resistance of the battery. When the battery is fully charged, the numerical accuracy is high. The test results are used for reference and comparison between the batteries d in the same batch. For those with high internal resistance accuracy requirements, please use a professional internal resistance instrument using the 4-wire AC method to test.

Test prince：

The DC impedance is that according to the physical formula R=V/I, the test equipment forces the battery to p a large constant DC current usually a large current of 10A-80A is used at present in a short time usually 2-3 seconds, measures the voltage at both ends of the battery at this time, and calates the current internal resistance of the battery according to the formula.

Capacity test accuracy reference：

The test results of five LGABB4 18650 batteries with a nominal capacity of 2600mAh in AUTO mode are as follows

How to use：

1、 Measuring internal resistance
The product uses the DC 2-wire method to test the internal resistance of the battery. When the battery is fully charged, the numerical accuracy is high. The test results are used for reference and comparison between the batteries d in the same batch. For those with high internal resistance accuracy requirements, please use a professional internal resistance instrument using the 4-wire method to test.

Test method:

Wait a few seconds after installing the battery, read the battery data, and the battery voltage and internal resistance s will be displayed. There will be a delay in data loading during battery loading and unloading, and the data will be checked after it is stable.

The circuit is disconnected when no battery is installed, and the resistance value is infinite

The circuit is formed after installing the battery, with an internal resistance of 88 m

Reminder：

*High accuracy of internal resistance measurement when the battery is fully charged
*When the voltage is insufficient, the internal resistance display may have an excessive value. Please reinstall the battery for measurement after the battery is fully charged
*The internal resistance of single battery is different, and the actual measurement results shall prevail
*There is line resistance when using the extension wire to test the battery, and the error will increase

2. Setting method：

2.1 Cli"ON/OFF/Menu" to switch menu options

2.2 Mode menu: clithe "Adjust" on to switch the mode

2.3. Stop discharge voltage: cli"Adjust" to switch the stop discharge voltage. The adjustment range is 2.5V~3.5V. The stop voltage is invalid for "CHG-charging mode".

2.4 Loop times: cli"Adjust" to set the cycle times. The cycle is only valid in "Auto". The cycle times are invalid in "CHG" and "DSG"

3. Start/Stop：

Clithe "Start stop" on to start the cargo suspension program

The program will display "STA:END" after running

4. Charge：

When charging, the charging chip and battery wilenerate heat, and there is high temperature in some parts. Pay attention to heat dissipation!!!

4.1、 Right Test ① Battery Charging

4.1.1 、Connect a DC5V power supply. The charging mode must be connected to an external 5V power supply. The right Test ① battery charging is controlled by the program, with a maximum charging current of about 1A.

4.1.2、 Adjustment mode:CHG, filling the battery to the right holder

4.1.3、Cli"Start/Stop" to run the program. The program starts. The indication status is charging. Only the time is recorded in the charging process, and capacity and energy are not measured. After charging, the program stops running. The indication status is "STA:END".

Measured charging time reference:
Charging 2157mAh, taking 3:37:35

4.2. Left battery holder charging：

4.2.1. Connected to a DC5V power supply, the charging of the left battery is not controlled by the program, but directly controlled by the hardware. The maximum charging current is about 0.5A. The red indicator light comes on when charging, and automatically turns off when fully charged, and the indicator light goes off.

5. Measuring battery capacity: the battery capacity can only be measured after the discharge is completed

When discharging, the load cement resistance wilenerate heat and high temperature, do not touch it, and enhance heat dissipation!!!

5.1 When the working battery left battery is fully charged, the discharge mode can be free of external 5V power supply. If the key fails without external power supply, please rep the working battery in time.

5.2. Adjustment mode: DSG, fill the battery to the right holder

5.3 Setting the stop discharge voltage

5.4 Cli"Start/Stop" to run the program. The program starts, indicating the status: discharge. The discharge process records the time, capacity and energy. After charging, the program stops, indicating the status: "STA:END".

The battery has a dynamic voltage drop under load. The voltage drop is the actual voltage that triers the stop

*Measured charging time reference:
When the fully charged battery is discharged to 3V, it stops, and the discharge is 1592mAh. The tion: 1: 53:10

6. Battery capacity division and running cycle: "AUTO" mode operation program：

6.1. Connected to DC5V power supply

6.2. Adjustment mode: AUTO, fill the battery to the right holder

6.3 Setting the stop discharge voltage

6.4 Setting loop times

6.5 Cli"Start/Stop" to run the program: the program starts, indicating the status: CHG represents the current running charging program, the charging process records the time, and capacity and energy are not measured; Automatically switch to discharge after charging, indicating status: DSG represents the current running discharge program, and the discharge process records time, capacity and energy; Switch to charging after discharging, indicating status: CHG, when the number of LOOP=1, the program ends after charging, indicating status: END. When the number of LOOP is greater than 1, the battery will enter the discharge mode again after charging. After entering the discharge mode, the time will be accumulated and the capacity and energy will be re measured. The charging and discharging cycle will be completed until the cycle is completed. The program is completed, the battery is fully charged, and the indication status is END.

*Measured charging time reference:

Discharged battery, automatic mode cycle test once: test capacity 2608mAh, time consumption: 9:59 : 26

*When the LOOP is ＞ 1, the capacity metering only records the discharge capacity of the last time, and the non average capacity

*The capacity, energy and time data will be reset automatically when the machine is shut down and the mode is switched
