    Arduino Battery

    Thank you so much for sharing such a nice idea. I have few question in my mind. May I use TIP122 DARLINGTON TRANSISTORS in place of BS170? And I want to charge 4.2 v 1 amp/h lead acid batteries (6 batteries connected in parallel such as + to + and - to -), how to change the schematics according to my situation?
