How can I make a low battery indicator for a 7.4 Li ion battery? Answered
I'm hoping somebody can help show me how to make one or help me find a schematic for one as I have no Idea where to look, Google search is overwhelming and none of the results are for a similar battery (and are too complex). I really only need a circuit with one LED that lights up when the voltage drops, nothing fancy.
The battery is 7.4 V as stated and is Li ion.
