I have 2s life batteries (1100 and 2200 mah) that I would like to make a discharger that will drain the batteries down to 2.5 volts.( I plan to discharge each cell individually). I plan to use a light bulb for the load and when the bulb goes out, I know the battery is at 2.5 volts. I had a discharger for other batteries, but have lost the design. I have searched online for schematics to do what I want, but the schematics are not designed to discharge to 2.5v. I am very much an amature, so I really can't take an existing circuit and change the values of the components to do what I would like it to do. The circuits that I have seen are very simple with only a few parts, (zener diodes, resistors, transisdtors, etc) Would someone please help me with what I would like to do? Thanks
