I have a cheap solar powered battery charger. The solar panel puts out approximately 7 VDC, not sure how many watts it can handle.
The charger can be used to charge 4 AAA, AA, C, or D batteries. I have attached a basic schematic.
I want to add some sort of indication to let me know that the batteries are charged. What do you suggest I do to accomplish this?
