Streamlining Versatility: Excel at every level of the battery value chain.
The BCS-900 series offers a modular, high-performance platform for battery cycling, designed to meet the needs of both research and industry. Each model provides precise current control and application-specific performance, with optional Electrochemical Impedance Spectroscopy (EIS) for advanced diagnostics.
Built on a shared architecture for consistency and seamless integration, the series includes:
BCS-905: Precision for Small Cells – Ideal for coin cells and other miniature formats, the BCS-905 delivers ±150 mA per channel and includes negative voltage capability for specialized low-voltage applications.
BCS-910: Versatility for R&D and Pilot Lines – With ±1.5 A per channel and negative voltage support, the BCS-910 is well suited for lab-scale research and pilot production environments.
BCS-915: High-Power Flexibility – Offering ±15 A per channel and scalable through parallel operation (up to ±120 A), the BCS-915 is built for demanding, high-current testing.
BCS-975R: Regenerative Performance for High-Energy Systems – Designed for large-format cells and energy-intensive systems, the BCS-975R delivers ±75 A per channel, with parallel operation enabling up to ±300 A. Its regenerative architecture allows energy recovery during discharge, enhancing efficiency in long-duration or high-power testing.
From precise low-current testing to regenerative high-power applications, the BCS-900 series gives you the flexibility to build a solution that grows with your needs—while maintaining the same reliable performance across the entire platform.
Precision, accuracy & modularity: three reasons to choose the BCS-900 battery cycler series.
Adaptable current ranges for each models of 900 series yield excellent accuracy allowing to adapt to the various current level situations to which the cell tester is confronted to with no compromise on accuracy.
Moreover, flexible voltage range possibilities are proposed. The standard models of 900 series allow to control and measure up to 10 V. BCS-905 (up to 150 mA) and BCS-910 (up to 1.5 A), targeting lower current applications and smaller cells are also available with negative voltage possibilities: BCS-905/n range from -2.5 V to 7.5 V whereas BCS-910/n from -5 V to 5 V. These models allow users to achieve tests for example such as the ones achieved on symmetrical cells.
An optional built-in FRA (Frequency Response Analyzer) is available for every BCS-900 module enabling native and fully integrated Electrochemical Impedance Spectroscopy (EIS) experiments over the frequency range of up to 10 mHz on each channel in either galvano or potentio mode. EIS measurements are as fast and precise as those obtained with our research-grade equipment – no compromise on quality has been made. With EIS, the evolution of your batteries’ parameters can be precisely determined (SOC, SOH, internal resistance Ri).

The instrument offers a fast data acquisition with a 1 ms sampling rate. Learn more about data of interest to work more efficiently.
The BCS-905-915 system is designed to allow you to simply and autonomously add modules to your system. Thanks to their modularity and compatibility, different BCS-900 modules can be combined in a single cabinet, in one of 4 sizes (6U, 12U, 24U and 38U), allowing users to build a custom-made battery cycling system that meets their exact requirements and can be easily upgraded for the future, while the BCS-975R comes complete in a 16U cabinet.
