BST8-WA is an eight-channel battery analyzer to analyze small coin cells and cylindrical batteries from 0.005 mA to 1 mA, up to 5V, with gold-plated pins for the best connection. Each channel of the analyzer has an independent constant-current and constant-voltage source, which can be programmed and controlled by computer software. This system provides most applications in battery testing fields such as electrode materials research, battery performance test, small-scale battery formation, capability grading, battery pack testing, etc. Brand new laptops with MS Windows 11, and the latest version testing software are installed and calibrated for immediate use (Up to 20 sets of analyzers can be simultaneously controlled by one PC).
