Accuracy you can audit
Accuracy and precision are published as two separate numbers, never blended into one, so you can verify the spec yourself instead of taking a vendor's word for it.
Independently verified
Designed and manufactured under an ISO 9001:2015-certified quality system, supported by an ISO/IEC 17025-accredited testing and calibration laboratory.
35 years of instrumentation
Founded 1991. Arbin reinvests 30% of profits into R&D, funding the precision architecture provided with every Arbin test station.
Built for any lab
Scalable channel density in a compact, air-cooled footprint, with open Python and C# API for the automation you already run.
Highlights of the LBTS-Cell Series
Four hardware decisions that separate the LBTS-Cell from a conventional cycler, and what each one changes about the data you create.
Market Leading Specifications
100 ppm precision, 24-bit resolution
See cell behavior - not tester uncertainty
Voltage and current measurement precision reaches 100 ppm (±0.01% FSR) and 200ppm (±0.02%) accuracy. 24-bit resolution provides fine control and measurement granularity across each current range.
Subtle shifts in resistance, voltage response, and coulombic efficiency remain visible and repeatable—helping you distinguish real cell behavior from measurement noise.
4 Current Ranges
auto-selecting, every channel
Provides the widest range of accurate output and measurement
Arbin was first to put multiple current ranges on a single test channel. Ranges select automatically, including during constant-voltage control, and the rated specification follows them.
Flexible Channel Paralleling
any number of channels
Group channels for more current
Any combination of sequential channels can be connected in parallel to raise the current ceiling for a single test article, rather than choosing from a fixed set of pre-wired banks. Paralleled operation reaches up to 1,200 A combined.
Built-In Safety Features
safety monitoring for every channel
Onboard computation and independent safety
Each channel computes capacity, energy, internal resistance, and efficiency in real time. Voltage, current, and temperature are all checked against safety limits independently of the test control loop.
Applications and Test Methods
Each channel operates as an independent potentiostat and galvanostat, so one chassis covers electrochemical characterization and long-run cycling at the same time.
Cell R&D and characterization
Resolve the small signals that separate one formulation from the next. Four current ranges per channel cover milliamp characterization and full-rate cycling without moving the cell.
Incoming QC and cell grading
Grade and sort incoming cells against your own pass criteria. Up to 256 channels per chassis with per-channel independence, so one failed cell never stalls a batch.
Impedance and electrochemical analysis
Every channel acts as an independent potentiostat/galvanostat. Native DCIM plus integrated Gamry EIS to 100 kHz put cycling and impedance in one time-aligned dataset.
Automated and adaptive testing
Drive the tester from your own software. ArbinCTI over TCP/IP plus Lua scripting support BMS emulation, digital twins, and adaptive fast-charge strategies.

Comparing systems?
Four hardware parameters decide whether test data is suitable to draw a conclusion from. Here is where the LBTS-Cell lands on each, and the question worth putting to every vendor on your shortlist.
| Parameter | Why it decides your data | LBTS-Cell | Ask any vendor |
|---|---|---|---|
| 해상도 | The smallest change the circuitry can detect. Too coarse and a resistance spike near end of life, or a dip in coulombic efficiency, simply is not in your data. | 24비트1 part in 16,777,216. Voltage and current alike. | How many bits? 16-bit is the common industry standard, and it is 256 times coarser. |
| 정밀도 | The noise floor. Noise obscures exactly the features dQ/dV and high-precision coulombic efficiency exist to reveal. | ±0.01% FSR100 ppm, specified separately for voltage, current, and time. | Is precision a hardware specification, or derived from averaged calculations and slow logging that hide the noise? |
| 정확성 | Whether the number is right, not merely repeatable. A tester can be precisely wrong all day. | ±0.02% FSRPublished as its own figure, never merged with precision. | Can you give accuracy and precision as two separate numbers? |
| Temperature stability | Ambient drift skews a test that runs for months. Gradual change tilts the data; sudden change steps it. | ~0.000185% / °CPatented shunt design, developed with Sandia's metrology group. | What is the temperature coefficient of your accuracy specification? |
Software and Safety
The two questions a lab asks after the specifications check out: can my team actually drive it, and what happens when a cell misbehaves.

Evaluated Side by Side Against Other Testers
“We did side-by-side comparisons of Arbin and other tester technology. Armed with this data, we moved forward with confidence using Arbin for what is critical to our electrification future [EV].”
“With Arbin, you can see minute changes in the battery and this gives researchers better predictability of when the end of life will occur in a reduced amount of time.”
“High precision measurements are not the only answer to understanding battery life, but it is a key component. Sandia National Lab brings their expertise in metrology and precision measurements and has helped Arbin as they’ve designed the new series of testers.”
R&D 100 Award — high-precision tester development
Through a three-year ARPA-E project funded by the U.S. Department of Energy, Arbin worked with Ford Motor Company, Sandia National Laboratories to develop high-precision battery testing at currents up to 200 A. The resulting architecture was subsequently extended across lower-current applications and now underpins the LBTS-Cell platform.
