Serum, 62,000 Joules per second! LOL You must have done calc error, that battery pack can deliver up to 3000 Joules continuously (per second) @ ....3000 watt (apparently) 62,000 Joules per second would be around 3300 amps

An RC car would/could never use this much power, it's more instantaneous power pulses. For those that don't quite understand, the capacitors energy is directly proportional to the instantaneous voltage of the cap, not taking into account the very small voltage drop between the two terminals.

energy formula: 1/2 (CV) C - capacity in farads, V - voltage in volts

Any questions or comments welcomed
