Hi lads, this post might sound repetitive, but my searches didn't produce any clear result, so here I am. My goal is to have an Arduino project running off a rechargeable single cell Li-Ion or Li-Poly battery, in both cases 3.7V. Planned discharge rate is a lot less than 1C so I believe both batte…

Oh, sorry, this is on the Arduino. You need a diode going from 5V to Vin on the Arduino.
