A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. …

batteries

The reason I''ve allowed such overkill on the amount of energy storage in the battery is that the limitation is the C rate, the current you can get from the battery to deliver your power. You can get higher C batteries (60 C are fairly obtainable, and I''ve seen one advertised as 135C!) but they get more expensive, and the 20-40C range is probably the …
