8-Channel 18650 Lithium Battery Module Auto Charge/Discharge Tester Capacity Internal Resistance Tester Feature: 1. The blue segment at the top is the external discharge terminal, and the lower end has a working indicator light for the corresponding channel 2. Voltage and current curve display, real-time voltage and current, DC two-wire method to measure internal resistance 3. The U-shaped groove 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 uses a compact battery holder, which is suitable for flat-head battery measurement 5. Channel type: 8 independent channels, each unrelated, independently running, and not affecting each other 6. Channel synchronization: Supports 8-channel setting synchronization, and can also set each channel parameter separately 7. Cyclic charge and discharge: In automatic mode, only charge-discharge-charge 1 cycle is supported, and multiple cycles are not supported

Product parameters: Working voltage: DC5V 10A (None as standard, power supply not included), overvoltage will burn the machine Power supply interface: ①: DC5.5 high current interface, ②: 5V positive and negative welding points Power supply reverse connection protection: reverse connection protection, reverse power supply prohibited ①Automatic mode: program starts~charge with 4.2V charging stop voltage, charging current is less than stop current for 30 seconds, first charge is completed~standstill (no charging and no discharge)~discharge according to stop voltage setting, load voltage is lower than stop voltage for 10 seconds, discharge is completed~standstill (no charging and no discharge)~charge with recharge voltage as stop voltage, when recharge voltage is set to 4.2V, charging current is less than stop current for 30 seconds, program ends (when recharge voltage is not equal to 4.2V, battery voltage reaches recharge voltage, program ends), recharge is completed, program ends, automatic mode operation is completed. ②Charging mode: program starts~when charging voltage is set to 4.2V, charging current is less than stop current for 30 seconds, program ends (when charging voltage is not equal to 4.2V, battery voltage reaches charging voltage, program ends)~charging is completed. ③Discharge mode: Program starts ~ load voltage is lower than stop voltage for 10 seconds, program ends ~ discharge is completed ④Activation mode: Only for professionals, testers are not allowed to leave during use! Forced charging with charge stop voltage, will not stop automatically, need to be ended manually. Charging current: Each channel is independent up to about 1A, and the charging current is not adjustable. Charging stop voltage: 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V, 6 levels are adjustable Recharge stop 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 End current: 100mA, 200mA, 300mA levels are adjustable Discharge current: Each channel is independent up to about 1A non-constant current discharge, and the discharge current is not adjustable. Discharge stop 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, 17 levels are adjustable. Standing time: 1~5 minutes level is adjustable. Status preview: Support 8-channel status 1-screen preview Single channel detail display: Support Single channel charge and discharge curve display: Support Internal resistance detection: DC two-wire method to measure internal resistance, only used for the same batch sorting analogy Heat dissipation method: Active heat dissipation Overheat protection: Support Cyclic charge and discharge: Only charge-discharge-charge 1 cycle is supported in automatic mode, and multiple cycles are not supported. External test: Support, external discharge can be connected through the 2P terminal, 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: reverse connection protection is available, reverse connection of battery is prohibited. Product size: 37×110×310mm Packaging size: 60×112×335mm
