Replace your car battery with capacitors!




So, would you like to shed 25-30 lbs. of dead weight from your car...???


If so, check this out.

Think you need large capacitors to do the job ?


Think again...

12V BoostPack



I'm going to do this... :D

I wonder what the long term effect on his car computers will be.

If this works so well, I have to wonder if race cars and or track cars are already into this technology.

God help him if those capacitors are made in China.

Thanks red :)

Did I miss where he said what the capacitors cost in the first vid?

Capacitors have self-discharge.

Couple that with the fact that the caps don't have a lot of amp-hour capacity, and your car will undoubtedly pull a tiny trickle of current to keep your clocks and settings in order...

So unless you plan to charge the car after it sits a few hours (which will undoubtedly result in a totally dead capacitor bank), you'll need a battery.

And then you've defeated everything.

Neat idea though as a boost option. If you could get 6 seconds of cranking out of a bank of them, it would be nice to have in winter.

2000+ cranking amps for the win ;)

Edit: Also without inter-cell balancing, a single cell could (theoretically) be overcharged by the cars alternator, resulting in a nasty explosion (or just the cap venting, YMMV).

Yes, he did say. The smaller pack was built with 6 capacitors that cost, IIRC, something like $10 each. The first pack, with bigger and cheaper capacitors, I can't recall what eh said they cost (or if he said :( )

When you watch the videos, you'll see how he tests and answers these problems... the "mini-boost pack" lasts a whole weekend in one test, cranking the car after three nights without a new charge from the ALT. For longer duration, he ultimately hybridizes the "mini boost pack" with a small battery.

Really quite cool. But I would think that the benefit in weight-loss causes a problem for FE by loading on the alternator, which will have to charge the capacitors pretty often. This might be a fun way to attempt to copy Mazda's capacitor charging regenerative braking system.

Just gonna borderline disclaimer: don't believe everything you see on YouTube.

I wouldn't mind seeing further independent testing regardless.

Heh. Today my roommate mentioned someone calling a radio show and mentioning the research that he did on YouTube. The host asked "Wait, what?"
