Automatic 5-Grade Cylindrical Battery Sorter in Stock – Ideal for 21700, 18650, and 26650 Lithium Cell Sorting

Product Overview

The SW-FX-5 Cylindrical Battery Sorting Machine is a professional-grade automatic screening system designed for lithium battery manufacturers and pack assemblers who demand consistent quality control. It efficiently sorts finished cylindrical cells—compatible with 18650, 21700, 26650, and 32650 formats (customizable)—into 5 distinct grades based on precise measurements of both voltage and internal resistance.

With a sorting speed of ≥4,000 cells per hour, this machine significantly improves production line throughput while maintaining reliable accuracy. Voltage and internal resistance are measured to 0.001V and 0.001Ω respectively, ensuring that every cell is matched with consistency for battery pack assembly, reducing imbalance risks and improving overall pack performance.

The equipment operates on standard 220V 50Hz power with a 1000W rating, making it easy to integrate into existing workshop setups. For advanced production management, the system offers test data query and archiving, and can be seamlessly connected to your MES system for full traceability. Optional accessories including barcode scanning, coding, and automatic material collection are available to further streamline your workflow.

Whether you are scaling up production or upgrading from manual sorting, the SW-FX-5 delivers a cost-effective, reliable, and expandable solution for cylindrical cell classification.
