Thanks Harald.
I am unsure about the voltage limitations, supposedly the input voltage must be at least Nx1.9 + 1.5 being N the number of cells. Is that right? If so then I need to supply at least 4*1.9+1.5=9.1v so the cells are properly charged. Im am not sure about the upper limit, should it...
Hi.
Once I used max713 to make a charger for my cordless screwdriver, the original B&D had a "class 2" charger consisting of a single transformer outputting 5vAC. For this project I used a wall adapter to get suitable output voltage for the max713 to use. That was a while ago.
This time I...
