Hi, Lower voltages do not cause any issues with the MOSFETs as far as I have tested down to 8V (note firmware cuts out at 10V). I have run an iron off 8V for an hour when testing this for safety without any noticeable increase in temperature on the MOSFETs. Remember the tip has a resistance in the range of 9-10 ohms, so at 10V it can draw a max of 1A (but practically it draws less). The gate on the FET's is driven with the incoming dc voltage (so for my tests it was still sitting at around -6-7V at the gate) which resulted in no more heat generation than when running on the full 24V power supply. 3S is actually a usable option for small joints or in a pinch. Quite a few users use the iron at 3S cells when in the field when running it quickly off a small pack to fix a small wire that came loose. The heat-up time is still bearable for one joint on 3S. As of my current testing, I have not found any warning necessary when running the unit with the current cutoff of 10V. This will be lowered to 3V/cell in future which is why I undertook the test on two of my units before I was willing to consider the lower input cutoff. Naturally my 2 units could be lucky, but also knowing that there is a large user base using 3S without issue I doubt the majority of units differ from mine.
So my TS100 arrived.
Tip: Read the instructions there is a hint about the tip set screw. I had mine taken apart wondering why the tip would not insert! Doh! All working now.
I love the speed it heats up with. Love the fact it will display it temp as it cools down. Haven't played with many of the settings except the temp so far.
However I think I need a tip with more mass to it. The pointy tip is a bit tricky to get heat into things fast with. I gather the tips aren't cheap. I'm debating a rounded point conical or a wedge/chisel tip.

1) Does the TS-100 seller state a firmware upgrade voids the warranty? (eg: https://github.com/Ralim/ts100#ts100 )

It has a warranty?

why would you go upto 300' and shorten the life of the tip?
you only need to reach the liquid-point of the solder.
330-350 for lead-free.

That's pretty unlucky! Just a thought, check that the mains adapter output isn't 'browning out' under cold start conditions. I know you bought a good one but it's not beyond the realms of possibility.
The only other one I can think of from when you opened it up. The micro is on a socketed daughterboard. It's held in place by a rubber pad, but it's just possible that you might have dislodged it.
Oh, one more - power it up via the micro-usb connector from a PC - obviously it won't be capable of heating but if you still get noise on the display, it narrows it down to a CPU related issue.
Good to hear that you got to experience its heating performance anyway.
