With the help of ezekiel181, I have finished my new on-board chargers.

I just have to say this is simply the best, most adaptable charger circuit I have ever made.

Here is the original post. 

This unit handles a ton of cells and can be adjusted for max charge time, charge current and works with many input voltages. It also includes a "data out" that goes low during the main charge and high during trickle. I have used this output to turn my cooling fans on and off. I was also able to get the chip itself as a sample --add this to the parts I already had on hand, I really only paid for sparkfun to fabricate the PCB's I designed around this circuit.

So there you go, one bad-ass charger that can be used for a bunch of stuff. I can not recomend enought that you goto the original post and find all the technical in's and out's.
