BST8-12 Eight-Channel Battery and Supercapacitor Analyzer with 5 mA–12 A Current Range and Up to 5 V Output, Includes Laptop Software
The BST8-12 analyzer is engineered to support comprehensive testing of various battery types and supercapacitors, addressing research and development needs such as electrode material evaluation, battery performance characterization, and small-scale battery formation. Its design accommodates current outputs from as low as 5 mA up to 12 A and voltages up to 5 V, enabling versatile testing scenarios.
Each of the eight channels operates independently with programmable constant-current and constant-voltage sources, controlled via included software on a supplied laptop. This setup allows simultaneous multi-channel testing with customizable parameters per channel, facilitating detailed lifecycle and capacity analyses.
