- Battery Runtime Calculator Estimate battery runtime from capacity (Ah or mAh), voltage, and constant load in watts (load-side) or amps (battery-side), with planning DoD and load-side efficiency. Runs locally in your browser.
- Battery Pack Sizing Calculator Size battery capacity (Ah) from load and runtime targets, with optional series/parallel cell geometry. Inverse of Battery Runtime (watts load-side / amps battery-side).

- Battery Pack Sizing Calculator Size battery capacity (Ah) from load and runtime targets, with optional series/parallel cell geometry. Inverse of Battery Runtime (watts load-side / amps battery-side).
- Battery Runtime Calculator Estimate battery runtime from capacity (Ah or mAh), voltage, and constant load in watts (load-side) or amps (battery-side), with planning DoD and load-side efficiency. Runs locally in your browser.
- Battery Runtime with Temperature Estimate constant-load battery runtime with a generic cold-derating heuristic about 25 °C. Extends Battery Runtime (watts load-side / amps battery-side). Planning model — not chemistry.
- Linear Battery Aging Calculator Estimate battery capacity with a simple linear cycle + calendar aging model: SOH = max(0, 1 − k_cycle·N − k_cal·t), C = C0·SOH. Default coefficients are illustrative. Runs locally in your browser.
