Item Number: BST8-20A-CDS


* denotes required field

Voltage Input
Computer Selection*

BST8-20A-CDS is a four-channel battery analyzer suitable for most applications in battery testing fields such as electrode materials research, battery performance & cycle test, small-scale battery formation, capacity grading, battery pack testing and etc. The purchase comes with a brand new laptop with Microsoft Windows with 30 days free trial Microsoft Excel and the latest version of controller software installed and calibrated for immediate use.

  • Extended testing current range from 20mA~20A, up to 5V
  • Benefits from the implementation of four independent constant-current & voltage sources, each channel can function independently without interfering each other.
  • 16bit Bipolar ADC/DAC module enables the stable and accurate voltage sampling
  • Dynamic loading protection function prevents the cell & device from damaging by the surge current
  • Advanced DCR testing function can screen out the unqualified batteries ahead of time due to the unstable metal contact 
  • Battery temperature monitoring capability

Channels & Test Modes

    Recipe Maker

  • Four independent programmable channels. Each channel can have different working modes and functions independently.
  • Working modes Include:
  • Charge: constant current charge (CC), constant voltage charge (CV), constant current constant voltage charge (CCCV), constant power charge (CP),  floating charge, 
  • Discharge: constant current discharge (CD), constant power discharge (CP), constant resistance discharge (CR)
  • Rest & cycles

Programs & Software

Real-Time Mornitoring

  • The software is included to set various working modes for evaluating cell capacity and life cycle for all types of rechargeable batteries
  • Limited threshold conditions include voltage, current, time, capacity, negative voltage slope, etc.
  • With real-time monitoring windows and integrated graph/data windows, the testing process can be observed more directly and efficiently
  • During the test, the software will provide instructions and warnings for assistance
  • MS Excel 2013 30 days free trial is pre-installed for you to output the Excel data file. (Note: Updated information on 5/21/2015)

Test Reports
and Curves for Analysis

  • Various curves can be created by software base on user definition. (Voltage-time curve, current-time curve, capacity-voltage curve, loops times-charge/discharge capacity curve, loops times-charge/ discharge efficiency curve, etc)
  • Data reports are created by software (export to Excel or .txt). User can easily compare the performance of the batteries tested in channels both visually and statistically

DCR Testability

The DCR Testing feature enables the Hybrid Pulse Power Characterization (HPPC) of the battery. Such function also provides the max/min voltage and current protection.

Temperature Measurement & Battery Clips

  • Each channel has a thermocouple for monitoring and recording the temperature of the batteries over the testing cycle.
  • 4 pairs of alligator clip battery connectors for universal connecting.

Protection and Auto-recover

If a power failure occurs during testing, the system will shut down all operating channels. Once power is recovered, the system will automatically resume those stopped channels and ensure that the test is normally conducted, so that no cases will lose any data.

Laptop Computer

  • Brand new laptop with MS Window 10, MS Excel 2013 30 days free trial is included and latest version testing software are installed and calibrated for immediate use
  • Up to 20 sets of analyzers can be simultaneously controlled by one PC
  • Notice: We strongly suggest you use an external hard drive to keep an instant backup of the collected data.


  • CE Certified
  • MET, TUV, CSA, UL certification are available upon request at extra cost


Two years limited warranty with lifetime support for the battery analyzer. (Note: MTI does not carry warranty for the Laptops. In this case service is needed for the laptops, please contact laptop manufacturer directly for warranty/non-warranty service.)
Operation Manual & Video
Application Notes 

  • If you like to run multiple battery analyzers on one Laptop, you can just buy multiple analyzers with one laptop. $300 will be deducted from the sales price if one analyzer is purchased without thbasic laptop.
  • Up to 20 battery analyzers can be controlled via one computer & software. 
  • Suitable for redox flow cell testing with cycling current up to 20Amps, please click the picture in below for details
