I'd like to see if I can build one of these myself.
This is this the first Google result I got for a circuit
Is it accurate? Meaning, is it the kind of thing I'm likely to find in a commercial model? If not, is a commercial model better in any respect? In what way is the $79 dollar unit "better" than the $11 dollar unit?
Thanks so much
Joe
ETA: My strategic concern is not specifically car batteries (although I may get one eventually) but large batteries in general, like UPS and jump starters.
