I have seen a few YouTube videos of this. Did you notice any improvements to fuel efficiency? Does it start quicker than with a lead acid?
I've been gathering up all my lead acid cores to sell to the local interstate dealer.
Considering something like this but between lacky soldering skills and diesel powerplant, I think I'm going to at least wait out the life of this battery.
Lastly,
Is this comparable to your super cap?
