How to use the Battery Cost Estimator
The Formula
Total cost = Ah × V × price per Wh. Energy (Wh) equals amp-hours times voltage, so you can compare packs of different voltages fairly.
Practical Example
Divide pack price by rated Wh to get $/Wh. Lower is generally better, but consider cycle life, warranty, and BMS quality—not just upfront cost.
