Sorry, I can't take credit for those extra FETs. Those were added by a guy named Sam Capri in Canada many years ago, and they are beyond my expertise or knowledge. They are soldered to a custom pc board strip he made. That IQ3000 also has a custom 2-in-1 eprom with the IQ3000 and Pro-Matcher Cell Grading software by him. They are accessed by flipping the toggle switch (with the power off of course) to the left of the main pc board. The switch is just barely reachable thru one of the side vents of the faceplate cover, so its not easily flipped by accident. I've also got another IQ3000 with a 3-in-1 eprom from Sam (IQ3000/Super-IQ/Promatch softwares). Sam was the master. Sadly, I do not believe he is dealing with them anymore, as his website has been gone for probably 6-7 years.
The lipo integration was done by me on the Super, just for the hell of it (people at the track have no idea what the heck it is

)
Like you, I loved messing with the NiCad/Nimh cells, but damn lipos are unbeatable
