I race small RC cars that run on 4 AAA NiMh batteries. I am trying to build a discharger that would discharge at about 1 to 1.5amp...but in series...then shut off completely. I don't want a parasitic drain left on them. I want to bring each cell down to .9 volts and stop. I understand that afterwhich, the batteries will spring back up a bit, but that is not a problem. Currently, modern dischargers discharge each cell individually and frequently seem to discharge lower than .9 volts. Discharging a pack of 4...in series..down to 3.6 volts and then removing the load seems to be more like the way they would discharge by running in the car.
I have done this manually by using a series battery holder...3 6 volt bulbs ...and sitting watching them with a multi-meter across...and waiting till they hit 3.6 volts....a bit time consuming. I would really like to build something that would automate this system.
Thanks
