Description:

 (The instruction manual is an old version and is for reference only.)

1. The blue part at the top is the external discharge terminal, and there is a working indicator light for the corresponding channel at the bottom; 2. Voltage and current curve display, real-time voltage and current, DC two-wire method to measure internal resistance; 3. The U-shaped on the back is combined with the PCB board, and the fan actively dissipates heat to form a heat dissipation channel; 4. The 18650 battery holder adopts a compact design, which is suitable for measuring flat head batteries; 5. Channel type: 8 independent channels, each channel is unrelated, runs independently, and does not affect each other; 6. Channel synchronization: supports 8 channels to set synchronization, and the parameters of each channel can be set separately; 7. Cyclic charge and discharge: In automatic mode, only one cycle of charge-discharge-charge is supported, and multiple cycles are not supported.

Feature:

1. Working voltage: DC5V 10A (non-standard, power supply not included), overvoltage will burn the machine 2. Power interface: ①DC 5.5 high current interface ②5V positive and negative welding points 3. Power reverse protection: reverse protection, reverse power supply prohibited ① Automatic mode: program starts~charge with a charging stop voltage of 4.2V, the charging current is less than the stop current for 30 seconds, the first charge is completed~static (no charging or discharging)~discharge according to the stop voltage setting, the load voltage is lower than the stop voltage for 10 seconds, discharge is completed~static (no charging or discharging)~use the charging stop voltage as the charging voltage, when the charging stop voltage is set to 4.2V, the charging current is less than the stop current for 30 seconds, the program ends (when the charging stop voltage is not equal to 4.2V, the battery voltage reaches the charging stop voltage, the program ends), charging is completed, the program ends, and the automatic mode operation is completed. ②Charging mode: Program starts ~ When the charging voltage is set to 4.2V and the charging current is less than the stop current for 30 seconds, the program ends (when the charging voltage is not equal to 4.2V, the battery voltage reaches the charging voltage and the program ends) ~ Charging is completed. ③Discharging mode: Program starts ~ The load voltage is lower than the stop voltage for 10 seconds, the program ends ~ Discharging is completed ④Activation mode: Only for professionals, testers are not allowed to leave during use! Forced charging using the charging stop voltage will not stop automatically and must be ended manually. Charging current: Each channel is independent when it is below 1A, and the charging current is not adjustable. Charge termination voltage: 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V, 6 levels are adjustable Charge termination voltage: 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 3.6V, 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V, 13 levels are adjustable Termination current: 100mA, 200mA, 300mA, each level is adjustable Discharge current: Each channel can independently discharge non-constant current up to about 1A, and the discharge current is not adjustable. Discharge termination voltage: 2.0V, 2.1V, 2.2V, 2.3V, 2.4V, 2.5V, 2.6V, 2.7V, 2.8V, 2.9V, 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 3.6V, a total of 17 levels adjustable. Standing time: 1~5 minutes, adjustable level Status preview: Support 8-channel status 1-screen preview Single-channel detailed information display: Support Single-channel charge and discharge curve display: Support Internal resistance testing: DC two-wire method is used to measure internal resistance, only for the same batch sorting analogy Heat dissipation method: Active heat dissipation Overheat protection: Support Cyclic charge and discharge: Only one cycle of charge-discharge-charge is supported in automatic mode, and multiple cycles are not supported. External test: Support, external discharge can be connected through 2P terminals, and a single channel can only support one of the battery holder or external test at a time, and the battery holder and external battery cannot be used for testing at the same time. Battery reverse connection protection: With reverse connection protection function, battery reverse connection is prohibited. Packaging size: 60×112×335mm Packaging weight: 480g
