Preparing for Fast Charge

Using available materials, I'm preparing for the first "pretty quick charge" test.

Using painter's tape to secure the 3000 farad capacitors to scrap plywood, I wired in an automobile starter solenoid (rated for about 300 amps).

I plan to stand about 15 feet away (and operate the entire setup on concrete) when I connect "9000 charged farads to 1000 depleted farads." It should be interesting and will probably occur Monday, May 20.

I don't think MOSFET are strong semi-conductors.

Are you sure? yes | no

Please I need full details about this fast charge or quick charge test.

Are you sure? yes | no

Perhaps I'm stating the obvious, but why risk the inrush? There are plenty of mosfets more than happy to handle this kind of current and then you could PWM it to control the charge rate.

Are you sure? yes | no

Probably get a nice beefy inductor and build a more efficient step-down regulator with current control too :>

Why risk the inrush though?
I'm guessing the tingling excitement of potential explosions? <.<

Are you sure? yes | no

So put on some Rush, and feel the rush of the inrush?

Are you sure? yes | no
