Description: The YPSDZ-0550 is a high-performance capacity tester designed for evaluating lithium battery cells. With capabilities for single-cell testing and high discharge current, it is ideal for use in EV maintenance, scientific research, and educational institutions. This fourth-generation tester ensures reliability through comprehensive full-load cycle aging tests before sale. Key Features: Capacity Testing: Measures the capacity of individual cells within the 1-5V range, suitable for various lithium chemistries including ternary lithium, lithium iron phosphate, manganese/cobalt/lithium titanate, and polymer cells. High Discharge Current: Supports a maximum charge/discharge current of 50A, with minimal MOSFET constant current discharge volume. Operating Modes: Single Charge/Discharge: Quickly charge or discharge individual cells. Cycle Mode: Determines battery capacity efficiently before grouping. User-Friendly Interface: Displays charging and discharging curves without needing a computer, making it easy to assess battery quality. Protection Features: Includes safeguards against over-voltage, reverse connection, current runaway, and overheating. Calibration and Accuracy: Factory and third-party calibration, with voltage accuracy 0.1% and current accuracy 0.1%. Authorized users can perform additional calibration. Cooling and Safety: Equipped with a cooling fan that activates at 40C and protects at 80C. Ensure regular fan maintenance for optimal performance.
