The Semco SI-Y BMST 1–24S (60A/120A) With Cabinet is an industrial-grade Battery Management System tester engineered for thorough validation of lithium battery protection boards used in EV, ESS, and industrial battery packs. Designed for 1–24S configurations (with expandable options up to 1–48S), the system integrates high-current testing, precision voltage control, and automated data handling in a safe, cabinet-style structure suitable for production floors and laboratories. Operating under stable AC 220V input and a wide ambient temperature range, the tester performs complete protection-function verification including overcharge, over-discharge, recovery behavior, over-current, and short-circuit response. Unique capabilities such as microsecond-level short-circuit testing, true per-string self-consumption measurement, and balancing current/voltage analysis make it especially valuable for high-quality BMS validation. Infrared barcode scanning ensures traceability, while modular high-current, voltage, and short-circuit simulation units provide accurate, repeatable results for both QC and R&D workflows.
Cell Aging Machines are designed to stabilize lithium-ion cells through controlled charge and discharge cycles, validating capacity, voltage consistency, and thermal behavior before assembly.

Battery Pack Testers perform complete electrical and safety validation, including voltage, current, insulation resistance, and protection checks.
