Fourchannel functionality Test up to four batteries simultaneously, enabling parallel performance assessment and faster decisionmaking. Independent operation Each channel runs independently, delivering accurate readings without interference, suitable for professionals and hobbyists alike. Automatic charge/discharge cycles Supports up to nine automatic charge and discharge cycles, automating testing routines and reducing manual effort. Active cooling system Includes an active fan cooling system to prevent overheating, ensuring reliable performance during extended testing sessions. Use scenarios Battery research and quality control: compare capacity, voltage stability, and cycle life across multiple cells or packs in parallel. Hobbyist and field testing: verify RC batteries or drone cells under controlled charge/discharge cycles to gauge endurance. Production QC: run batch tests on incoming or finished batteries to confirm consistent performance.
