The setpoint is adjustable. I don't know if nicads are amenable to my charging scheme or not. You can see the detaila of the controller at Elec-trak.com in the classifieds. Or here:

Hm. 38 volts is probably too low, and you need to take NiCDs to 45 volts in order to complete charge. Most of the time they hang around 43.0 volts while charging away. Also pulse or low current charging tends to cause the batteries to gas instead of charge.

That's ok; I'm getting close to just building a BQ2004 based chip to control the charger. I'll still have the timer as a fail-safe, but it will ultimately throw a relay along with a 2004 chipset.
