ATORCH Voltage Digitally Controlled Adjustable Constant Current Discharge Load Aging Tester, US Plug

HK$420.00 HKD

1. Four operation modes: constant current operation; constant voltage operation; constant power operation; constant resistance operation
2. This time, a flexible input wiring port design is adopted. Users can manually connect different adapters to achieve different measurement functions to extend the functions
3. Automatically generate measurement data reports, stop voltage and time-limited discharge
4. First turn off the load switch "OFF", measure the current battery no-load voltage, and then turn on the load switch "ON" through the setting key. At this time, you can read the internal resistance parameters of the current battery. The internal resistance of this table is calculated by the formula: (no-load voltage-load voltage)/current current=battery internal resistance
5. Long press the setting key, and then short press the setting key when it flashes to switch to time-limited discharge for timing setting to obtain the effect of worry-free discharge aging. The time-limited discharge can be set to count down for any length of 1-99 hours and 59 minutes. When the set time is reached, the discharge will automatically stop. It can be used as a timer to turn off the constant current discharge aging function
Real-time display of internal and external dual temperature measurement data, three intelligent safety protections
6. Test various USB data cables/chargers. First, use a data cable to connect the corresponding interface of the load device, and then use the DC power cable and Android cable to connect to the "Micros input detection port". Then adjust the current by setting the button to detect the voltage drop of the data cable and the performance stability of the charger.
7. Test various DC power adapters, and the 2.4-inch high-definition large color screen displays data clearly.
8. The four-wire wiring method, the voltage measurement is not affected by the voltage drop of the wire, making the voltage measurement more accurate.
9. Easily test various data such as voltage/current/capacity of various lithium batteries/batteries.
10. Long-term 180W load discharge aging test, the temperature is kept at about 50-80 degrees.
11. Adopting intelligent temperature control light effect fan design, built-in large discharge tube, more powerful and more reliable, test the overall capacity of the battery, usage time, aging performance, etc.

Trustpick

18650 Lithium Battery Capacity Automatic Charge Discharge Internal Resistance Tester

HK$56.00 HKD

1. Working power supply: DC5V external power supply or 18650 battery (both need to be prepared by yourself)
2. Applicable batteries: batteries that meet the stop discharge voltage of 2.5~3.5V and 4.2V charging are applicable
3. Power supply interface: Type-C interface, power supply line is prepared by yourself (C port mobile phone line)
4. System language: Chinese, English
5. Test quantity: 1-way charging and discharging measurement (only right battery)
6. Internal resistance measurement: Support, use DC two-wire method to test internal resistance
7. Charging function: Support, 1-way program control about 1A (MAX) charging; 1-way hardware control about 0.5A (MAX) charging
8. Discharging function: Support, only 1-way supports about 1A (MAX) discharge and automatically stops when the condition is met
9. Automatic charging and discharging: Support, the battery is fully charged at the end of automatic mode (stop voltage is set to 2.8V or above)

16. Weight: 80g
17. Product size: 110×88x30mm

Test method:
Wait a few seconds after installing the battery, read the battery data, and the battery voltage and internal resistance parameters will be displayed. There will be a delay in data loading during the battery loading and unloading process. Check after the data stabilizes

About capacity test:
The discharge must be completed to measure the capacity. I have never met anyone who wants to measure the capacity just by installing the battery. Discharge takes time. You have to wait for the discharge to end automatically to have a complete capacity in the discharge stage

This product uses the DC two-wire method to test the battery internal resistance principle:
DC impedance is based on the physical formula R=V/I, the test set The battery is forced to pass a large constant DC current (currently 10A-80A is generally used) in a short period of time (usually 2-3 seconds), and the voltage at both ends of the battery is measured, and the current battery internal resistance is calculated according to the formula. The DC two-wire test internal resistance is the result of the middle line resistance, and the result is used for reference comparison between batteries tested in the same batch. Due to the influence of contact resistance and battery self-loss, the internal resistance may not be identified normally and cannot be measured. For those with high requirements for internal resistance measurement accuracy, the TS235 internal resistance tester (AC four-wire method) can be used for internal resistance testing.
