I think it's better to think of batteries as a chemical reaction for creating (not storing) electrons, and capacitors are more of a high pressure storage of electrons directly (meaning you could...

A lot of current (and even slightly older) Mazda and Ford passenger cars use an oil/coolant heat exchanger which both cools the oil when it's up to temp as well as heating it up faster when it isn't....

I went a different route; 4s4p bank of LiFePo4 cells at 8 AH each.
This is for my daily driver/race car (daily racecar?) and weighs around 12 lbs. I went this route after looking over lead acid/cap...

Not very well. Cap banks can supply a lot of instant amperage but the voltage drops off quickly at high loads. Think about it like this: Each cap in my 500 farad cap bank (huge; they are 2.7v 3000...

Sounds like you've not sized your bank properly. I'd estimate you need a bank of 6 3k farad caps to push a reliable 700 amps through that truck long enough to get it started; from 15v down to 10v...

Well, it takes power to run the compressor, which is made by fuel, which in internal combustion engines is not 100% efficient. Thus, it will produce extra heat in the engine when running.

I'm going to be experimenting with printed cases for Raspberry Pi cameras (which are quite small) for my next daily and race car instead of using mirrors altogether.

I've been testing a Pi (Model...

It may also be significantly easier to fit the 12 pack, not to mention the additional balancing that happens if you connect them up a certain way (6 parallel banks of 2 caps connected in series)....

I think there's feedback issues with disabling the alt outright. What you might have to do is set up a small cap bank (using the 300 farad caps maybe?) to take on the role of allowing current through...

You'd want to go to a smaller pulley on the alt (if even available) if it's not putting out proper voltage at idle due to the change in the crank pulley (but that defeats the purpose).

I'd still do 6, or at least set up a balancing system that will bleed the extra voltage off (diodes would be best).

Also, I have the strangest nerd boner right now.

Edit: Keep in mind that your...

To measure the total consumption, just use the farad rating of your bank combined with start voltage and end voltage.

For instance, if you have a 100 farad bank, and the voltage when started has...

You could easily double up on the LEDs for cheap, vs purchasing a new solar panel. Also, diodes are usually a couple pennies and can be purchased in the same...

Yes I have thought about that, but I'm short on room and I doubt that the cap bank would make things significantly better, as the set of 650 caps I have will have a total capacitance of 108.3 farads,...

Actually it seems to me that when the cells are charged and maintained, they don't leak down as bad. The first time I charged them, leakdown was pretty bad. They got down to 12.62 volts in 19 hours,...

Hey folks.
