18650 Battery Capacity Tester Module Lithium Battery Internal Resistance Tester 8-Channel Accessory

Features:External Discharge Terminal and Working Indicator: The blue segment at the upper end is the external discharge terminal, and the lower end has the working indicator of the corresponding channel.Voltage and Current Display: Voltage and current curve display, real-time voltage and current readings.DC two-wire method to measure internal resistance.Heat Dissipation: U-shaped groove at the back is combined with PCB board, and the fan actively dissipates heat to form a heat dissipation channel.Battery Holder: 18650 battery holder using a compact battery holder, suitable for flat battery measurement.Channel Type: 8 independent channels, each unrelated, independent operation, without mutual influence.Channel Synchronisation: Supports 8 channels to set up synchronisation. Also, can set up each channel parameter individually.Cycle Charging and Discharging: Only supports charging-discharging-charging 1 cycle in automatic mode, does not support multiple cycles.Specifications:Display: 2.4in LCD ScreenApplicable Battery: Can accommodate 8pcs 18650 batteries (Batteries are not included)Working Voltage: DC5V 10A (Standard bare metal, without power supply). Overvoltage will damage the machinePower Supply Interface: DC5.5 high-current interface, 5V positive and negative welding pointsPower Supply Reverse Protection: Built-in reverse protection. Reverse power supply prohibitedCharging Current: Each channel independently maximum about 1A, non-adjustableCharging Stop Voltage: 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V (6 adjustable steps)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 adjustable steps)End Current: 100mA, 200mA, 300mA (adjustable)Discharge Current: Each channel independently maximum about 1A, non-constant current discharge, non-adjustableDischarge 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 adjustable steps)Standing Time: 1~5 minutes (adjustable)Status Preview: Supports 8-channel status preview on 1 screenSingle-Channel Detail Display: SupportedSingle-Channel Charging and Discharging Curve Display: SupportedInternal Resistance Detection: DC two-wire method, only for same-batch sorting analogyHeat Dissipation Mode: Active heat dissipationOverheating Protection: SupportedCyclic Charging and Discharging: Only 1 cycle of charging-discharging-charging is supported in automatic mode. Multiple cycles are not supportedExternal Test: Supported. Can be discharged through the 2P terminal external. A single channel can only support the battery holder or external test at a time. Cannot use both simultaneously.Battery Reverse Connection Protection: Built-in reverse connection protection. Reverse connection of the battery prohibitedModes:Automatic Mode: Program starts → Charges at 4.2V until current Charging Mode: Program starts → Charges at 4.2V (or user-set voltage) until current Discharge Mode: Program starts → Discharges until load voltage Activation Mode: For professional use only. Forced charging at stop voltage. Manual termination requiredNOTE: To ensure optimal performance and safety of this product, we recommend installation and use by professionals with relevant expertise. Users may also refer to online installation tutorials for self-installation. In case of any issues, please feel free to contact the seller for support.Package Included:1 x Detector1 x Crowbar
