Up to 120 A by parallelization
5 current ranges on every module
Cell tests up to 10 V and down to -5 V (/n models)
Native EIS: 10 mHz – 10 kHz

Manufacturer: Bio-Logic SAS, Seyssinet-Pariset, France · Authorized distributor for Türkiye: Entek Elektronik

Overview

The BCS-900 series is a modular battery cycling platform built from three modules (BCS-905, BCS-910, BCS-915) designed for the most demanding test and cycling applications. It offers five current ranges, high resolution, high-precision coulometry, fast bandwidth and seamless integration with external equipment.

Optional fully native EIS provides fast, high-quality impedance measurement on every channel; key parameters such as SOC, SOH and internal resistance are monitored without compromising data quality. Thanks to the embedded operating system and local redundant storage, tests do not depend on a PC; channels can be hot-plugged while tests are running.

The result is a modular platform suited to battery testing in industry, academia, quality control and certification. Supplied with the BT-Lab® Suite software.
