Defining the DT50W-20 System Application

The DT50W-20 is defined as a professional-grade lithium cell maintenance system, distinct from standard testers by its ability to perform active charge/discharge cycling. It is engineered specifically for battery pack manufacturers to execute precise capacity grading (mAh sorting) and internal resistance (IR) matching. By processing 20 cells simultaneously with independent channel control, it ensures the voltage consistency required for high-quality battery pack assembly, significantly reducing pack imbalance issues in the field.
