Laboratory Battery Testing System
LBT-Benchtop Series
High-precision cycling and characterization for coin, cylindrical, and pouch cells from 100 µA to 10 A — four auto-switching current ranges per channel, 24-bit measurement resolution, and an independent potentiostat/galvanostat on every channel. Available as a standard benchtop chassis, or as an all-in-one system with an integrated 10 °C to 60 °C temperature chamber in the same footprint.

Accuracy you can audit
Measurement accuracy held across all voltage and current ranges, with precision published as a separate specification.
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 LBT-Benchtop Series
Four hardware decisions that separate the LBT-Benchtop 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.
Potentiostat Per Channel
Full potentiostat and galvanostat control
Electrochemical work on a benchtop chassis
Every channel functions as an independent potentiostat and galvanostat with an embedded microcontroller for real-time calculations, plus a second voltage input and a PT100 input mapped to that channel. EIS runs to 100 kHz through Gamry integration or Arbin's DCIM technique.
GITT, PITT and voltammetry run without a separate bench instrument, and one stalled cell never stops the rest.
Chamber Without a Chamber
integrated option, same footprint
Temperature control that fits on the bench
The all-in-one option adds a temperature chamber inside the chassis, controlling 10 °C to 60 °C to ±0.5 °C stability and adding only three inches of height. Cells load on interchangeable trays, and PT100 sensing per channel can drive step-level safety logic.
No walk-in chamber, no floor space, no facility infrastructure — a single-phase outlet runs either configuration.
Two Ways to Configure the Same System
The measurement hardware is identical. The only decision is whether temperature control belongs inside the chassis or in a chamber you already own.
Standard Benchtop
The measurement chassis on its own, at 16 × 17 × 13 in. Cells sit in external holders or in a chamber you already own, controlled through MITS. The widest configuration choice of the two, including the 16-channel builds and the 0 to 10 V range.
- Channels per chassis
- 8 or 16
- Voltage ranges
- −5 to 5 V, 0 to 5 V, 0 to 10 V
- Maximum current per channel
- 10 A
- Chassis size (W × D × H)
- 16 × 17 × 13 in
- Temperature control
- External chamber via MTCI, or MZTC
Best when the lab already has chambers, when a 16-channel count matters more than integrated thermal control, or when cells need to move between fixtures.
Mit integrierter Kammer
The same measurement hardware with a temperature chamber built into the chassis, three inches taller overall. Cells load on interchangeable battery trays, each with a pressure relief valve, rotary door locks and a stainless-steel chamber interior. Two configurations carry the tighter measurement rating.
- Channels per chassis
- 8
- Voltage ranges
- −5 to 5 V, 0 to 5 V
- Maximum current per channel
- 10 A
- Chassis size (W × D × H)
- 16 × 17 × 16 in
- Temperature control
- Integrated, 10 to 60 °C at ±0.5 °C
Best when temperature-dependent behaviour is the object of the test, when bench and floor space are the constraint, or when a turnkey system has to arrive ready to run.
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.

Voltage, Current, and Channel Ranges
Four current ranges come with every channel and switch automatically, including during constant-voltage control. Available channel counts depend on the configuration and on whether the integrated chamber is fitted.
| Spannungsbereich | Current Ranges per Channel | Channels — Standard Benchtop | Channels — With Integrated Chamber |
|---|---|---|---|
| −5 to 5 V | 1 A · 50 mA · 2 mA · 100 µA | 8 or 16 | 8 |
| −5 to 5 V | 5 A · 500 mA · 20 mA · 1 mA | 8 or 16 | 8 |
| 0 to 5 V | 5 A · 500 mA · 20 mA · 1 mA | 8 | 8 |
| 0 to 5 V | 10 A · 500 mA · 20 mA · 1 mA | 8 | 8 |
| 0 to 10 V | 5 A · 500 mA · 20 mA · 1 mA | 8 | K.A. |

Comparing systems?
Four hardware parameters decide whether test data is suitable to draw a conclusion from. Here is where the LBT-Benchtop lands on each, and the question worth putting to every vendor on your shortlist.
| Parameter | Why it decides your data | LBT-Benchtop | Ask any vendor |
|---|---|---|---|
| Resolution | 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. | 24-Bit1 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. |
| Präzision | 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? |
| Genauigkeit | 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? |

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.
