IIUC it would be different for each kind of cell per the discharge curve on the datasheet where it also shows that 0% is at some voltage determined by the manufacturer, definitely higher than 2.5V. They say lithium should be at 40% for long term storage so it seems fine.

Awww, there is no spoon. Holler back when you get some 10kW Mach-Lorentz thrusters in stock.
BTW, I detected one realism: PWR LED could very well be a dummy light that comes on when Power-to-Weight Ratio is insufficient. ;)

It wasn’t PhotoShop or an invasion. RedBot only wanted to hang out. In the spotlight. Caught on tape.

Wow, that’s kind of sad. This is also why I got the cheap coffee maker with a switch and neon lamp instead of one with a bunch of buttons, not only because the extra $10 was good for buying coffee.
I was just going through this kind of rant in my head this morning, due to an overpriced screensaver that likes to “crash” to desktop with an unhelpful error message about something wrong with the 3D engine and then sit there… not restarting because as far as Windows knew, it was still running. When I was asked to set it up to run constantly for public display, the first thing I did was say “NOOOooo it’s going to throw error messages on your screen and make your place part of an ongoing bad joke” but they insisted. The next thing I did was to insist on a laptop for power saving considerations, and I found an i3 on eBay that wasn’t entirely presentable, but cheap… it turned out to be an i5 because someone goofed, so that’s neat. Then I installed Tiny7 to avoid all the helpful things that Windows would otherwise try to do or send up on the screen, to have a nice bare minimum of background tasks, and to make reboots predictably and consistently fast. When it was all set up, I disabled the wifi and left the ethernet unplugged, just in case someone was clever and malicious enough to get in, they still wouldn’t be able to deface the “sign”. I hoped, I really expected that I prevented all the Error’d sort of failures. I made a little happy bubble where stuff would Just Work and it wasn’t enough, because the main event, the centerpiece, is a piece of junk.
After it started “crashing” I installed AutoIt to run in the background, waiting for that message box in order to close it. Eventually the AutoIt scripts grew to include several other messages including the error reporting form which, again, was actually part of the screensaver program and so would block Windows from the core function, preventing screen burn. I also had to schedule the OS to reboot itself every night because occasionally the screensaver would stop animating– it actually freezes without crashing or even throwing an error and the background sound it makes just keeps on cheerfully playing. Clearly, this was not designed or tested to run for more than hours at a time.
Anyway, I am happy about AutoIt and I had practically gotten over the whole mess when it came up with a new message, just recently after a power failure:
Your settings file has been corrupted, starting with defaults
[ OK ]
No, it’s not OK. IMO, any screensaver that waits for user input, while not animating and with no timeout, is failing hard. So, in the infinite loop of the primary AutoIt script, I added a line that would overwrite the settings.txt file from a ‘master’ before launching the program. We’ll see how long that lasts.

Ah, sweet– the simple 32MHz discrete setup in this M1 is called Pierce. Thanks for the clue. I could wish it was as easy to find names for things from descriptions as it is to find descriptions from names, but now I don’t even have to hunt. +1 for oscillators because the differential pair sort of reminded me of Royer oscillators as in CCFL inverters.
