I’m planning to make a ebike with 1.2-2kW motor with 3.3kwh battery, but the Lion battery are costly, so I decided to go with LifeP04 and supercapacitor hybrid battery bank. I am confused on making battery bank out of supercaps as they don’t have C rating, Mah, can anyone help me with this. ---

They don’t have a C rating as such. Super caps can’t deliver energy at constant voltage, so they will not be useful for this purpose. ---

But I have planned to use super caps for initial stage for acceleration and switch to LifeP04 for attaining top speed
