The Battery Testing System 5V 30A–5V 200A is a high-accuracy platform engineered for cell and small pack testing where low voltage and high current performance are critical. Powered by AC 220V ±10%, 50 Hz with 2127 W input power, it uses 16-bit AD/DA resolution and input impedance ≥1 MΩ for clean, precise signal acquisition. The system supports a CV output range of 0.025–5 V with ±0.1% FS accuracy and excellent stability ±0.1% FS, making it ideal for stringent R&D and production testing.

Each channel delivers 0.15–30 A with ±0.1% FS current accuracy and 150 W output power, maintaining ±0.2% FS power stability. A CV cut-off current of 0.06 A ensures accurate termination of constant-voltage charging. Fast current response time (≤20 ms) and flexible step timing up to 365×24 hours/step allow simulation of complex long-term test profiles. The system supports advanced charge/discharge modes—CC, CV, CCCV, CP, CR, pulse and DCR calculation—with rich cut-off conditions based on voltage, current, Δtime, capacity, -ΔV, ensuring precise control and protection during every test cycle. With min 100 ms data logging, 10 Hz sampling, and up to 65,535 cycles and 254 steps, it is built for deep lifecycle, performance, and reliability evaluation of lithium and other 5 V-class cells.
