Well thanks for the advice all. Just to let everyone know, it is now built and seems to work well. The only strange thing I have noticed is that after the batteries are charged, they seem to slowly lose some of their charge and tend to go back to being "dead" after like a day or two. I guess this just means I will have to charge them to a higher voltage to compensate. As for the issue of exploding batteries, I have pluse charged them at up to an average current of 150ma and I have seen no problems. They dont even get warm!
Pictures to come soon.
