Battery cell selection & validation for pack manufacturers and OEMs
Identify the cells that meet your requirements, predict how your battery will perform and age, and understand your warranty risk before you commit.
KuryLabs brings together our own laboratory testing, intelligent modelling and four connected engineering tools, so your team can make better battery decisions without starting every cell evaluation from scratch.
Try all four tools on three lab-tested demo cells. No credit card needed.

testing laboratory behind the data
How much data is available depends on the cell reference and how far its validation has progressed.
Companies we work with at Kurybees, through laboratory testing, engineering studies and joint R&D.
Cell cost, decision speed, laboratory spend and warranty exposure. Each one is measurable, and each one moves when you choose the right cell earlier.
€0
from €0.10 saved per cell across 1,000,000 cells
Compare more cell options against your real requirements and find a lower-cost fit for a new or an existing pack. Saving just €0.10 per cell adds up to €100,000 across one million cells.
Hours
from an urgent customer request to an informed shortlist
Facing an urgent customer request? Use lab data and simulation to shortlist cells and reach an informed decision in hours, then spend your physical validation on the strongest candidates only.
Fewer tests
lab time spent only where it changes the decision
Screen more options before you commit lab time. Point your team and equipment at the tests that matter, lower your operating costs and avoid equipment you do not actually need.
Before launch
ageing and warranty exposure estimated on your own use case
Cell choice shapes pack life and warranty exposure. Simulate ageing under your use case and estimate the warranty risk before launch, then turn durability into a stronger total cost of ownership for your customer.
Our commitment
A €0.10 saving per cell across 1 million cells is €100,000. A few months saved on a development programme can be worth far more. KuryLabs is built to deliver that kind of return.
We agree upfront on how value will be measured across cell savings, time saved, testing costs and warranty risk. The goal is always to create significantly more value than the cost of using KuryLabs.
Measured together, agreed before we start
Benchmarking cells is essential work. It is also repetitive. Every new project seems to start with the same groundwork, and that groundwork occupies your laboratory and pulls your engineers away from the product itself.
KuryLabs gives your team a shared foundation of cell data, models and engineering tools. You can look at more candidates, and you can point your own testing at the decisions that actually need it.
Most teams evaluate the same handful of cells project after project. With existing data on hand, you can afford to look at alternatives you would normally skip, and some of them may offer a better balance of performance, lifetime and purchasing cost for your application.
If a characterisation has already been done, there is little reason to repeat it. Use that data and keep your own benches and engineers for the pack-specific work: integration, thermal design and final validation.
Start with an initial model, then tighten your analysis as laboratory measurements arrive. Your project advances in parallel with the testing programme instead of waiting for every result before the first decision.
Three tools, used in order, take you from the first screening pass to a validated cell decision you can export and continue with in your own engineering environment.
You start from your application, your operating profile and the constraints you cannot move.
Pack Designer works through the possible configurations and picks out the cells that actually fit your energy, power, voltage, mass and other targets.

Cells that fit
Put the shortlisted candidates side by side and look at the data that exists for each one.
Electrical performance, resistance, rate capability, thermal behaviour, ageing and measured dispersion are all there. For cells we have tested, you can open the experimental results behind every comparison.
Measured results and model-generated estimates are always labelled apart, so you know exactly what you are weighing when you make the trade-off.
What you walk away with
A cell selection backed by relevant data, and a clear picture of what still needs validating.

EstimatedRun the electrical, thermal and ageing behaviour under the profile your product will actually see.
Compare duty cycles, temperatures and charging strategies. Watch how performance drifts over time and check whether the design is likely to meet the lifetime and warranty you have promised.
Try the alternatives on screen before you commit to a physical test programme.
What you walk away with
Design choices you can defend, with a clearer view of performance, lifetime and warranty exposure.
The whole workflow in one line
KuryLabs helps you make the cell decision. It doesn't lock you into another engineering environment. Once the decision is made, take the data and continue development in your existing engineering environment.
And once the battery is in the field…
Combine accessible measurements with calibrated models to estimate state of charge, state of health and remaining useful life. Revisit your assumptions once real batteries start returning data.
The library currently holds dozens of cell references, and it keeps growing. For each one, the electrical, thermal and ageing information sits in a single place instead of being scattered across datasheets and test reports.
When we fully characterise a cell, our testing and processing workflow produces around 10,000 data points. That is what feeds the performance analysis, the model calibration and the lifetime predictions.
New references do not have to wait for a full test campaign. They can enter the platform early with a model built from manufacturer data and our own algorithms. Laboratory testing then adds real measurements over time and the model gets stronger with each batch.
Your project keeps moving while the evidence catches up.
Stage 1 of 3
An initial model built from manufacturer information and our algorithms. Good for early screening and first design exploration, but not a substitute for laboratory validation.
Stage 2 of 3
Experimental results are starting to come in. Measurements are added to the initial model as they arrive, and the scope of what has been tested is spelled out.
Stage 3 of 3
The model has been checked against laboratory measurements within the stated testing scope and operating conditions, and our engineers have judged it robust enough, based on their expertise, to be marked as validated.
Electrical, thermal and ageing validation rarely advance at the same pace, so a cell can have measured electrical results while its ageing model is still preliminary. We keep that visible, and when we say a cell is lab-validated we mean within a stated scope, not for every temperature, duty cycle or ageing condition imaginable.

This record is illustrative. Actual fields and values depend on the cell and how far its testing has gone.
Missing a reference you need? Tell us which one and we will talk through what it would take to integrate and test it.
You're not buying software. You're accessing years of laboratory work, models, data and engineering tools.
KuryLabs is built by Kurybees, an independent battery R&D company. We test cells in our own laboratory, we build the numerical models, and we sit alongside engineering teams when they need a second pair of hands.
The laboratory work covers electrical characterisation, cycling and calendar ageing, heat generation and mechanical breathing analysis. Those measurements are what the cell evaluations and the system-level simulations rest on.

cp and k (axial, radial)Industrial teams have put our approach and our models through their own scrutiny. They now use KuryLabs, our laboratory data or the engineering work we deliver alongside it to support their battery programmes.
Faster simulation is only part of the value. The rest comes from tests you no longer need to repeat, engineering hours you get back, cells you would not have found otherwise, and lifetime costs you can see early enough to act on.
On a cell-replacement project we will look at whether 10 to 30% lower cell purchasing costs are realistic while you keep the performance you need.
That is a target we investigate for your specific project, not a promise. What is achievable depends on your current cell, the technical requirements, your volumes and the commercial terms available.
The point is not to find a cheaper cell. It is to find a technically suitable alternative and then work out what it is really worth at the scale of your programme.
Gross purchasing savings
€100,000€0.10 on each of 1,000,000 cells, before qualification costs, any other incremental costs and the service fees we agree together.
These figures are illustrative. Real outcomes depend on your baseline cell and commercial conditions.
Pick the level of access that matches how you work, whether that is a first evaluation or a development programme that never really stops.

Send us your requirements, your operating profile and what you are trying to achieve. Our engineers take it from there, whether that means screening and comparing cells, running the simulations, adding tests in the laboratory or writing up technical recommendations.
You get the engineering results and the deliverables your project needs, and nobody on your side has to learn or operate another platform to get them.
We agree the scope, the deliverables and the budget before anything starts. Then we do the analysis and come back to you with the findings, the assumptions behind them and what we would recommend.
When a project qualifies, we can be paid as a share of the savings you actually make on cell purchases. The percentage is agreed before we start, so both sides know the deal.
We look for technically suitable alternatives to the cell you use today and help you through sourcing. Our remuneration comes out of the savings the project generates.
Need more lifetime, power, range or fast-charge capability? We structure remuneration around the additional value created.
We identify the cell and design changes that unlock the performance improvement you need, and our fee is tied to the measurable value those improvements deliver.
The things engineering teams usually want to know before their first evaluation.
Before any paid engagement starts, we agree with you on how value will be measured across four levers: cell purchasing savings, engineering time saved, laboratory testing costs avoided and warranty risk reduced. We track those figures together. If we cannot demonstrate at least €10 of value for every €1 you pay KuryLabs, you pay nothing. The measurement method is written down up front, so there is no debate afterwards about what counts.
