Precision Battery Discharger
This is a precision battery discharger for 8.4V 7-cell Ni-Cad or Ni-MH batteries. The project made a cheap, reliable discharger circuit with an easy visual indication of the battery’s state (discharging or discharged) with less than 10$ of parts. Most parts can be found around the house or taken from broken electronic equipment - or at worst, purchased from Radio Shack.
