Battery Power

by aitneinc on Thu Jan 27, 2011 12:20 pm

Is it possible, through the use of regulators or series/parallel batteries, to use a 4.7v lithium-ion battery to power a 5VDC board? If so, what sort of circuitry would be required? Any help would be GREATLY appreciated.

Chances are:

The specifications of the board allow the 5V to be low by some amount (translation: look at the specs of the board)
The 4.7V battery actually charges to some voltage higher than 4.7V

So that means: Just hook the battery to the board.

If you really do need 5v look into a boost converter.
