Early Supporter Access
Current Estimation Pro
The calculator is free — all current features are available today via the Full mode toggle. Pro is the paid tier for the advanced features listed below, currently in development. Buy now to support the project and receive your license key automatically when each feature ships.
- ✓Accuracy PackComing soonBattery aging model, temperature derating, self-discharge rate, usable depth-of-discharge, and Peukert factor — so your estimate reflects real-world degradation, not just datasheet specs.
- ✓Confidence ViewComing soonBest / typical / worst-case battery life bounds shown simultaneously. Stop reporting a single number — show the full uncertainty range to your team or customer.
- ✓Solar Pro PackComing soonLocation-based peak sun hours (10 climate zones), real-world derating cascade (temperature, soiling, cable loss, mismatch), energy balance card, seasonal analysis, and reverse sizing — find the minimum panel wattage for break-even.
- ✓Scenario CompareComing soonClone your project, tweak parameters, and compare configurations side-by-side with absolute and % deltas on battery life and average current.
- ✓AI Datasheet ExtractionPlannedPaste a part number — get run and sleep currents pre-filled automatically. Powered by LLM with a confidence score; always editable before committing.
- ✓Monte Carlo Lifetime SimulationPlannedRandomise key parameters within tolerances and run thousands of simulations. Outputs a probability distribution of battery life — ideal for reliability analysis.
