I noticed the same things, but I wasn't sure if any of the real ground 
work had been done. I've been replacing the cells in my batteries for a 
while now because I get 40-60% more gain from home built compared to new 
batteries from the manufacturer. I'm just tired of the licensing from 
the software I was using because it limits how many eeproms you can re 
flash.
