Questions about A123 cells

[BrianG]

I generally don't like to get "nice" things from RadioShack because they are usually overpriced. So, I've never used that PS before - not sure if it'll do what it claims while keeping a steady and noise-free voltage.

If an adequate computer power supply won't do it for you, I've had good luck with my Aston 25A PS. Nicely built and you can tweak the voltage up a bit. I pumped mine up to 14.5v (typical vehicle voltage with enging running) so the current doesn't have to be as high for a given power requirement.
