It's called a Gravity 1000 amp car battery capacitor. 1000 amps. That's awful hard to believe. It's for sale but I can't find any information about it what-so-ever. Like: How big is it? How much does it weigh? And what is it's true capacity? (Amp/Hours)

1000amps doesn't really mean much, it's probably peak 1000amps over a tiny fraction of a second. If you want higher output, just use more batteries - it seems as it is the current battery setup is sufficient for the design.
