All, I am building a small PIC based IR sender which will attach to a =20 moving object. As there is no power source it will have to be battery powered. I was =20 thinking of 3 AA batteries with an in-circuit charger. The IR LED has =20 a Vfwd of 1.5v, I can pick a PIC that will operate at 3v. So two easy questions: 2) Is there anything better than simple AA batteries? 3) Recommendations for your favourite battery charge IC, so I can go google= ..
