1Pcs Type-C 18650 Lithium Battery Capacity Tester 8 Channel MAh MWh Digital Battery Power Detector Module Internal Resistance Tester Support Automatic Charge Discharge

18650 battery holder using a compact battery holder, designed for flat battery measurement. Voltage and current curve display, real-time voltage and current, DC two-wire method to measure internal resistance, intended only for same-batch sorting comparison. 8 independent channels, each unrelated, operating independently without mutual influence. Supports synchronized setup across 8 channels, and also allows individual parameter configuration for each channel. The blue segment at the upper end serves as the external discharge terminal, while the lower end features the working indicator for the corresponding channel. The U-shaped groove at the back integrates with the PCB board, and the fan actively dissipates heat to create a heat dissipation channel. Only supports charging-discharging-charging 1 cycle in automatic mode, does not support multiple cycles. Supports external testing, allowing discharge through the 2P terminal externally; a single channel at a single time can only support either the battery holder or external testing, not both simultaneously. Working voltage: DC5V 10A (standard bare metal, without power supply), overpressure will damage the unit. Power supply reverse protection is included; reverse power supply is prohibited
