How to Select the Voltage and Current Range
The voltage and current range should be selected according to the cell type, nominal voltage, capacity and charge-discharge test rate. Higher voltage models are suitable when the test process or cell design requires a wider voltage window, while current selection should match the cell capacity and test standard.
Information Needed for Quotation
- Cell type, size and capacity
- Required voltage and current range
- Channel quantity and daily testing capacity
- Charge, discharge, rest and cycle test steps
- Data report and export requirements
- Fixture type and cell holder requirement
