Well, my battery powered super maxed out ppa is nearing completion. I'm going to use a 12 cell AAA config, the calculator says 23.75V. Do I need a regulated switcher? Gawd, I hope not... this has been one expensive project!

I was thinking of an open frame 24V switcher, just case it up. But if I can get away with a wallwart....

A TEPS from tangent! If you read throught the TEPS project history you'll see that steps was originally developed to feed the PPA baterry board.

If you REALLY wanted to go the lazy route, an Elpac could do it, though I will leave it to you to figure out the best one for the job.

I built the exact same configuration for my PPA, and built the STEPS too. It has worked flawlessly for 4 months. I also use the STEPS to power my PIMETA and Millet HB... you should consider building one...
