Hi
I found this Battery Equal Charge Indicator circuit here
http://freecircuits.wikidot.com/
(The third circuit down the page)
I was wondering why such an elaborate circuit is used. Cant I just stick the batteries as inputs to an op amp and use the output (if they are unequal) to drive some sort of indicator?
I am sure there is some sort of explanation that eludes me. I'm a beginner. Could someone explain this to me please?
