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 RBT-Cell Series
Four hardware decisions that separate the RBT-Cell from a conventional high-current cycler.
Regenerative Energy Recovery
up to 83% returned to the grid
Cut the energy cost of every cycle
SiC power stages return up to 83% of discharge energy to the facility grid. Channels share a common DC link within each module, so energy leaving a discharging channel is reused directly by a charging channel before anything is drawn from the mains, cutting the energy cost, and the HVAC load, of every cycle.
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), with ±0.01% FSR current accuracy and ±0.015% FSR voltage accuracy. 24-bit resolution provides fine control and measurement granularity across each current range, taken through 4-wire Kelvin connections.
Subtle shifts in resistance, voltage response, and coulombic efficiency stay visible and repeatable even at full current.
Flexible Channel Paralleling
any number of channels
Group channels for more current
Any combination of channels on a module 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 1,600 A per module.
Test a higher-current cell with the channels you already have, without a second system.
Built-In Safety Features
safety monitoring for every channel
Independent monitoring, separate from control
Each channel module runs a dedicated microcontroller for precise control plus a second, redundant microcontroller that watches voltage safety limits on its own. Protective fuses sit on the IV channel boards, and thermoswitches with variable-speed fans hold the cabinet inside thermal limits.
Device profiles set safety thresholds automatically and block a test from starting if reverse polarity is detected.
Applications and Test Methods
Up to 400 A per channel and 1,600 A paralleled, with regenerative circuitry that returns discharge energy to the grid across long high-current programs.
High-current life cycle testing
Cycle large-format cells at up to 400 A per channel for months at a time. Regenerative circuitry returns up to 83% of discharge energy back to the system and the grid.
Incoming QC and cell grading
Grade and sort incoming cells against your own pass criteria at production current. Up to 64 channels per chassis, each running its own schedule and safety limits.
Fast-charge and drive-cycle simulation
Upload drive cycles and duty profiles as time vs. current, power, or load with set points down to 10 ms. Lookup tables adjust the output against measured voltage, temperature, and state of charge.
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
One measurement specification, one software platform, across the full current span Arbin builds for cell testing — from 100 mA characterization work up to 1,600 A+ high-current cycling.
| 电压范围 | Current Ranges per Channel | Channels per Chassis |
|---|---|---|
| 0 to 6 V | 100 A / 25 A | 16, 32, 48 |
| 200 A / 50 A | 8, 16, 24 | |
| 400 A / 200 A / 50 A | 4, 8, 12 | |
| 0 to 10 V | 100 A / 25 A | 16, 32 |
| 200 A / 50 A | 8, 16 | |
| 400 A / 200 A / 50 A | 4, 8 | |

Primary 0-to-X voltage ranges are listed above, and alternative voltage windows are also available: −6 to +6 V and 2 to 6 V; −10 to +10 V and 2 to 10 V; and 2 to 20 V. Available channel counts vary by voltage window.
Comparing systems?
Four hardware parameters decide whether test data is suitable to draw a conclusion from. Here is where the RBT-Cell lands on each, and the question worth putting to every vendor on your shortlist.
| Parameter | Why it decides your data | RBT-Cell 电芯测试 | Ask any vendor |
|---|---|---|---|
| 分辨率 | 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. | 高等级、1 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. |
| 测量与控制精确度（Precision） | 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? |
| 测量和控制准确度（Accuracy） | Whether the number is right, not merely repeatable. A tester can be precisely wrong all day. | ±0.015% 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.
MITS Software

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.
