Real Test Data

Everything you need to design a pack

From raw cell data to complete bill of materials, CellBench covers the full design workflow.

Real Discharge Data

Every cell model is built from actual discharge tests at multiple currents. No manufacturer optimism -- real measurements from 0.2A to 30A.

Pack Simulation

Configure series/parallel layouts, set wiring resistance, and simulate discharge. See voltage sag, runtime, and energy delivery instantly.

Mission Profiles

Pre-built load profiles for drones, ebikes, eskate, and more. See how your pack handles real-world usage patterns, not just constant current.

Compare Side-by-Side

Put two pack configurations next to each other. Different cells, different layouts, same load -- see which one wins on weight, cost, or runtime.

Three steps to your next pack

Go from cell selection to simulated performance in minutes.

01

Pick your cells

Browse tested cells, compare discharge curves, and choose the right cell for your application. Filter by capacity, max current, weight, or chemistry.

02

Configure your pack

Set your series and parallel count, define wiring resistance, and choose a BMS. CellBench calculates voltage, capacity, weight, and cost.

03

Simulate & compare

Run discharge simulations at any current or load profile. Compare multiple configurations to find the optimal balance of weight, cost, and performance.

Built for builders

Whether you are building for range, power, or weight, CellBench helps you make the right trade-offs.

Ebike Builders

Maximize range without overbuilding. Find the sweet spot between pack weight and watt-hours for your commute.

Drone Pilots

High discharge rates and minimum weight. Simulate burst loads to make sure your pack can handle full throttle.

Eskate Riders

Balance top speed with hill-climbing torque. See how voltage sag affects your ride at different discharge rates.

DIY Powerwall

Low discharge, high capacity. Optimize for energy density and cycle life when weight does not matter.
