I was interested in taking either this (2x3.7v 1300mAh):http://www.adafruit.com/products/258
Or this (1x3.7v 2600mAh):http://www.adafruit.com/products/328
And charging them using this:http://www.adafruit.com/products/259
My dillema seems to be that that charge cant handle two cells and having two plugins for charge on a robot is not consumer friendly. On the other hand 3.7v is not enough to drive my project as my arduino wants 7v-12v in and my servos and sensors want 5v out from the arduino.
Power supplies are not my strong point is there a way that I can use the 2600mAh 3.7v to give my project 7v it needs?
