    256 Channel 5V 3/5/6A Lithium-Ion Battery Grading Machine ...
    A capacity grading machine is a specialized, automated system that evaluates, measures, and classifies lithium battery cells—cylindrical or prismatic—based on performance metrics like capacity, voltage, and internal resistance. It charges and discharges cells to ensure they are matched for uniformity in battery packs, enhancing lifespan and reliability. 
    This video demonstrates how a simple, portable battery tester compares to a more professional, expensive one:

    Key Features and Functions 
    • Modular Channels: Machines often feature 256 or more independent channels, allowing simultaneous testing of multiple cell types or batches.
    • Automatic Sorting: Cells are graded (e.g., A, B, C or specific Ah ranges) and sorted based on capacity, voltage, and internal resistance to ensure pack consistency.
    • High Accuracy: The equipment provides high precision (typically ~0.05% accuracy) and records data points, such as voltage and current, as frequently as once per second.
    • Testing Parameters: Functions include constant current/voltage charging, discharging, and recording the charge/discharge curve to analyze performance.
    • Safety Protections: Systems come equipped with protective features like over-voltage, over-current, and under-voltage protection, along with data breakpoint recovery. 
    Common Applications 
    • Cell Manufacturing: Used in production lines to sort cells after formation.
    • Battery Pack Assembly: Critical for matching cells in electric vehicles, energy storage systems, and power tools.
    • Performance Testing: Research and quality control for evaluating battery lifespan and reliability.
