I am trying to build a battery life indicator:
I have a couple of questions about it:
1. Will it be fine if I simply hook up my 7.4v batteries to the circuit?
2. About what voltage is a 7.4v battery about to die, so that I can set it at that?
3. Which model of transistors I should use? It doesn't specify..
Thank you
