Presently I am making one robot for which i require 12 v source. I have a 12.6V LI-ION battery pack (contains three 4.2V, 1400mAh cells in series), but the problem is I dont have the charger for it. The charge in the market costs high.
So how can I make a charger for the same which is cost effective as well as which can charge fast???
Can I use simply the voltage regulator 78xx series IC???
And what are the things taken to care while designing a charger???
If anyone has a charger circuit please post that to me on my mail ID.
