Interface & Panel Description
Panel Controls Description
  • Power switch: If the power is suddenly cut off during the test, the test data will not be saved.
  • Display screens: Display charging and discharging parameters and discharge curve.
  • Coding switches: Rotate to adjust working mode, press to set parameters.
  • Start/Stop button: Any operation in running state must be paused first.
  • Battery positive input: 1-2-3 pin through current, 4 pin voltage detection.
  • Battery negative input: 1-2-3 pin through current, 4 pin voltage detection.
Important Reminder

99% of the failures are caused by too small contact area between the battery clamp and the battery pole ear/bad contact/too large charge and discharge current/cell damage. Although the battery clamp has clamped the battery, but if the contact area is not large enough, it will lead to various failures, it is recommended that you make your own battery clamp!

Usage Instructions
Step 1 System Initialization & Parameters Setup

Start up first, and then clip the battery. Press the setting knob to enter the setting page, rotate left and right to adjust the parameters, press to determine, set the parameters correctly and save the exit.

Usage Parameter Setting Screen
Parameters to be set in charging mode:
  • Charging End voltage: Lithium titanate 2.7-2.8V, 18650/ternary/polymer 4.1-4.2V, lithium iron phosphate 3.6-3.65V (You must set this parameter correctly and reasonably).
  • Charging current: Set to 10-20% of the cell capacity. It is recommended to set a current that makes the cell heat less as much as possible.
  • Judging full current: When the charging current is less than this value, it is judged to be fully charged. Recommended settings: cell below 5Ah: 0.2A; cell of 5-50Ah: 0.5A; cell above 50Ah: 0.8A.
Parameters to be set in discharge mode:
  • Discharge End voltage: Lithium titanate 1.6-1.7V, 18650/ternary/polymer 2.75-2.8V, lithium iron phosphate 2.4-2.5V (You must set this parameter correctly and reasonably).
  • Discharge current: Set to 10-50% of the cell capacity. It is recommended to set a current that makes the cell heat less as much as possible.
Parameters to be set in cycle mode:

Charge and discharge mode parameters need to be set simultaneously.

  • Keep voltage: The cut-off voltage of the last charge in cyclic mode, can be the same as the cut-off voltage of the charge or discharge.
  • Resting time: In cycle mode, after the battery is fully filled or discharged (let the battery cool down for a period of time), usually set for 5 minutes.
  • Cycle Count: Max 5 times.
    1 time (charge-discharge-charge)
    2 times (charge-discharge-charge-discharge-charge)
    3 times (charge-discharge-charge-discharge-charge-discharge-charge)
Parameters to be set in Voltage balancing mode:
  • Discharge End voltage: Target voltage to balance the cell. This value must be higher than 10mV than the battery voltage.
  • Discharge current setting reference: Less than 10% of the cell capacity is recommended.
  • End current: It is recommended to set it to 0.01A.
Step 2 Select Mode and Start

Return to the home page, rotate the setting button to the left or right to switch to the working mode you need, press the start / stop button to enter the working state, and press again to pause.

Working Mode Selection Screen
Step 3 Test Completion & Results Retrieval

After waiting for the test to end, the result page will automatically pop up (press any button to stop the alarm sound) and record it manually test the results, and then test the next battery.

Test Result Page
Interpretation of Test Results:
  • "1" indicates the first cycle, showing the AH/WH/min of charge and discharge respectively. Press the start / stop button further to show the results and curve of each step in turn.
  • The yellow numbers represent the voltage axis, and the yellow curve represents the voltage curve.
  • Green numbers represent the current axis, and green curves represent the current curve.
  • When the battery performance is good, the voltage and current should show a relatively smooth curve.
  • When the voltage and current curve rises and falls sharply, it may indicate a pause during the test, excessive charging/discharging current, or high internal resistance indicating the battery is close to failure.

Notice: If the test result is empty, the working step was less than 2 minutes, meaning the data was not recorded.
