I tried to build a simple circuit that would send current through a resistor if it was no longer being drawn by the load.
I thought I could do it with a PNP transistor with the charger on the Base, the resistor on the collector, and the voltage source on the emitter. That didn't work.
Any simple circuits that you guys know about that will do what I need. I've attached a block diagram. This idea is that a stepper motor will create a 5V power source, but if the battery is charged, the 5v power source will bleed off through the resistor.
