I'm pretty sure you would need a trunk sized super capacitor bank just to have a chance to start a 12V vehicle, they need a few hundred amps for around 2-5 sec.
@@thatbillguy5211 no you won't. A car, even a large car draws no more than about 300A for 1-2seconds. To power the car's starter for 2seconds, we need: IV(t) = 300A × 12V × 2sec = 7200 -10,000joules A bank of 5-6 of these supercapacitors would give 13.5v - 16.2v, more than the needed 12v to start the car. 6x 3000F supercapacitors in series would give 16.2v 3000F. The energy it stores is: ½CV² = 0.5 × 3000 × 16.2² = 393,660 joules So unless my math is wrong - correct me, Else this should work theoretically and practically.
Give me 2 capacitors like this. I'm from Brazil and these capacitors are very expensive and I can't afford to buy them. I want to make a super Power bank
