nwmtnbkr _ Actually I think your planning to but 8 - 20ah cells not 10ah. I know someone does make them but I don't think TS does. No of course I don't mind you asking about the brass studs......but I just won't tell you. Just kidding. Actually they aren't brass their steel serated bolts that had a coating on them. But I am looking for brass, bronze or copper ones to replace them if I find something better. So far I haven't had a problem though. There is a name for them but right not I just can't think of it. But they are typically used on a car wheel to hold the wheel on. I bought a size I though would work and cut off the threaded end to size and pressed them into the plastic.
