I'm looking for a charger that isn't crazy over the top full of features, but will allow me to charge, a 4 cell TX 800mAh Ni-CAD AA pack, a 5 cell 2/3A 1400mAH NIMH hump, and a 5 cell 4200mAH NiMH C hump. On a 12v power source, basically what I want is just something that will let me charge NiCAD and NiMH and not overcharge them, I don't need something ultra super fast like some crazy quad fan cooled 10 minute ultra charger.
