Using capacitors instead of lead-acid batteries for an E-bike raises questions about energy storage and voltage stability. To achieve 1 Amp hour at 12V, approximately 600 Farads would be needed, considering voltage drop during discharge. Unlike batteries, which maintain voltage until nearly depleted, capacitors lose voltage significantly as they discharge. The discussion highlights the impracticality of using capacitors for this application, suggesting that a more complex setup with multiple capacitors and voltage regulation would be necessary. Overall, the consensus is that relying on capacitors for E-bike power is less feasible than traditional battery systems.
