• 20 independent channels
Each channel runs separately; no interference between channels. Supports individual control and simultaneous operation of 20 cells.
• Modular & stable design
Industrial module structure, high safety isolation, supports series battery pack direct connection without wrong‑connection damage.
• High precision & efficiency
High‑accuracy voltage & current sampling; fast active balancing to improve cell consistency and prolong battery life.
• Full compatibility
Works with ternary lithium, LiFePO4, 18650, pouch cells, square cells and large‑format cells.
• Intelligent PC software
Real‑time curve display, data recording, automatic grouping, export reports and one‑key management.
• Multiple protections
Over‑voltage, over‑current, over‑temperature, reverse connection and short‑circuit protection for safe long‑time running.
1. Cell capacity grading (C/GC testing)
Full charge → full discharge → automatic capacity calculation for sorting good/bad cells.
2. High‑efficiency balancing
Balances voltage differences between cells; improves pack performance and cycle life.
3. Programmable charge/discharge steps
CC/CV charge, CC discharge, rest, cycle (up to 5000 cycles) supported.
4. Automatic battery grouping
Group by capacity range, voltage range; indicator lights for quick identification.
5. Data analysis & export
Real‑time voltage/current/capacity curves; DCIR internal resistance comparison; export to Excel.
6. Multi‑device cascade
Connect multiple units via PC for large‑scale production testing.
