I was thinking is there a way to make it so when a battery goes below a certain voltage it switches to a backup battery. For instance, in my remote control car I want to make a modification so you can have two batteries plugged in at once. The second battery will not be supplying any power to the car until the first battery goes below, let's say, 4V.
EDIT: I've looked through the other post about battery switching circuits - They aren't really what I need.
Thanks,
